About the Notes from A.C. Bent

The following section by Bent captures the feeding behavior of the Roadrunner which is one of our most entertaining birds.

flycatcherwise - refers to the habit that flycatchers have to better hold the insects that they catch.

Notes from A.C. Bent

Sometimes, traveling in a motorcar, we come upon him perched on a fence post or telegraph pole close to the highway. Now we have opportunity to observe how slim he is, how long his legs, how noticeable his crest. But as we pass he leaps to the ground, swings off through the cactus clumps, and is gone. Once more only a glimpse! Once more only the retreat of a timid desert creature that appears to be half bird, half reptile. 

But lie in wait for the roadrunner! Watch him race across the sand, full speed, after a lizard. Watch him put out a wing, change his course, throw up his tail, change his course again, plunge headlong into a clump of cactus, and emerge, whacking his limp victim on the ground. Watch him jerk a slender snake from the grass, fling it into the air, grasp it by the head or neck, pummel it with his hard mandibles, and gulp it head first. Watch him stalk a grasshopper, slipping quietly forward, making a sudden rush with wings and tail fully spread. frightening the doomed insect into flight, then leaping 3 or 4 feet in air to snatch it flycatcherwise in his long bill. Watch the roadrunner for an hour at his daily business of catching food and you will deem him among the most amazing of all the desert's amazing creatures. Snake-killer indeed! Chaparral cock! Not by sitting quietly on fence posts, not by slipping shyly from the path, has the roadrunner earned for himself these bloodstirring names!

Notes from A.C. Bent

Nesting: Unlike the European cuckoo, both of our North American species usually build their own nests and rear their own young, though they are very poor nest builders and are often careless about laying in each other's nests or the nests of other species. Major Bendire (1895) gives the following very good account of the nesting habits of the yellow-billed cuckoo:

The Yellow-billed Cuckoo is one of the poorest nest builders known to me, and undoubtedly the slovenly manner in which it constructs its nest causes the contents of many to be accidentally destroyed, and this probably accounts to some extent for the many apparent irregularities in their nesting habits. The nests are shallow, frail platforms, composed of small rootlets, sticks, or twigs, few of these being over 4 or 5 inches in length, and among them a few dry leaves and bits of mosses; rags, etc., are occasionally mixed in, and the surface is lined with dry blossoms of the horse-chestnut and other flowering plants, the male aments or catkins of oaks, willows, etc., tufts of grasses, One and spruce needles, and mosses of different kinds. These materials are loosely placed on the top of the little platform, which is frequently so small that the extremities of the bird project on both sides, and there is scarcely any depression to keep the eggs from rolling out even in only a moderate windstorm, unless one of the parents sits on the nest, and it is therefore not a rare occurrence to find broken eggs lying under the trees or bushes in which the nests are placed. Some of these are so slightly built that the eggs can be readily seen through the bottom. An average nest measures about 5 inches in outer diameter by 1 1/2 inches in depth. They are rarely placed over 20 feet from the ground, generally from 4 to 8 feet upon horizontal limbs of oak, beech, gum, dogwood, hawthorn, mulberry, pine, cedar, fir, apple, orange, fig, and other trees. Thick bushes particularly such as are overrun with wild grape and other vines as well as hedgerows, especially those of osage orange are most frequently selected for nesting sites. The nests are ordinarily well concealed by the overhanging and surrounding foliage and while usually shy and timid at other times, the Yellow-billed Cuckoo is generally courageous and bold in the defense of its chosen home; the bird on the nest not unfrequently will raise its feathers at right angles from the body and occasionally even fly at the intruder.

Of five Massachusetts nests, on which I have notes, the lowest was only 2 feet above the ground in some bushes, and the highest was 12 feet up in a crotch near the top of an oak sapling in a swampy thicket near a brook. Owen Durfee mentions in his notes a nest 5 feet up in a juniper on the edge of a swamp. The others were at low elevations in thickets along brooks.

A. D. DuBois has sent me his notes on five Illinois nests; one of these was on the end of a branch of an apple tree, 8 feet from the ground, near a country schoolhouse; this nest contained 3 eggs of the cuckoo and a robin's egg. Another was near the end of a branch in an osage-orange hedge, 10 feet tip; still another was in an isolated clump of willows, between a field and a pasture, 6 feet from the ground.

But cuckoos do not always nest in such low situations; there are several records of their nesting well up in elm trees. Grant Foreman (1924) tells of a pair that nested on his place in Muskogee, Okla., for one or two years, high up in an elm tree; he says: "The next year after nesting in this inaccessible place, they built their nest in a little elm tree in the parking, in a low limb overhanging the curb on an asphalt street where hundreds of automobiles were passing every day, and here in this exposed, noisy place they raised a brood of young. This year they built their nest in a little hackberry tree in the parking along the side of my lot; but here also the nest was on a low limb overhanging the curb on a paved street, and the ice wagon stopped every morning directly under this nest, which was so low down that the driver might have put his hand in it."

George Finlay Simmons (1915) mentions a nest that he found near Houston, Tex., on the horizontal limb of a young pine near the edge, of some woods. He says of it: "The nest was a slight platform about eleven feet up, through which I could see with ease; it was composed of small pine twigs, about an eighth of an inch in diameter and averaging six or eight inches Iong, and was much more concave than I had expected. This shallow saucer was neatly, though quite thinly lined with a few pine needles, a small quantity of Spanish moss and several tiny buds."

George. B. Sennett (1879) says that in the Lower Rio Grande region of Texas "ebony trees near the ranch, mesquites among cactuses, thorny bushes in open chaparral, and open woodland, were favored breeding places."

Wright and Harper (1913) found a well-made nest in Okefinokee Swamp, in a tupelo tree at the margin of the Suwannee. "It was placed in a cluster of mistletoe on a horizontal branch four feet above the water, and consisted of sticks interwoven with Spanish 'moss' (Tillandsia usneoides)."

Dr. Harry C. Oberholser (1896) gives the measurements of four nests; the average height of the nests was 4 inches, and the greatest outside diameters averaged 7.63 by 6.25 inches.

Both species of North American cuckoos often lay their eggs in each other's nests. The eggs of the yellow-billed cuckoo have been found several times in nests of the robin and catbird. H. P. Attwater (1892) writes: "In 1884 I found a Dickcissel's nest which contained five eggs and one Yellow-billed Cuckoo's egg. The next year some boys brought me three Black-throated Sparrow's eggs and one Yellow-billed Cuckoo's, from the same field, which they said they found all together in one nest." J. L. Davison (1887) says: "I also found a nest of Merula migratoria, taken possession of by Coccyzus americanus before it was finished, which was filled nearly full of rootlets; and in this condition the Robin laid one egg and the Cuckoo laid two and commenced incubation, when a Mourning Dove (Zenaidura macroura) also occupied it and laid two eggs and commenced incubation with the Cuckoo. I found both birds on the nest at the same time, when I secured nest and eggs. The eggs of the Robin and Cuckoo were slightly incubated; those of the Mourning Dove were fresh."

Bendire (1895) adds the wood thrush, cedar waxwing, and cardinal to the list of birds that have been imposed upon, and says: "Such instances appear to be much rarer, however, than those in which they interlay with each other, and the majority of these may well be due to accident, their own nest having possibly been capsized, and it compelled the bird to deposit its egg elsewhere. Such instances do occur at times with species that can not possibly be charged with parasitic tendencies." Marcia B. Clay (1929) thus describes the cuckoo's method of gathering twigs for her nest:

Flying into an adjacent apple tree containing a considerable quantity of dead material, the Cuckoo landed on a limb, selected a dead twig, and grasping it in her bill bent it back and forth until it snapped from the limb, whereupon she flew with it to her nesting-site in the next tree, arranged this twig and quickly returned for another. As she tugged at a stubborn twig, her back was arched and very long tail curved under or waved about If a twig resisted too well her attack, the bird desisted at once and tried another. Always she worked rapidly with great energy, attacking a twig as soon as she landed in the tree, never carrying more than one twig at a time, holding It squarely at right angles to her bill and flying rapidly with long tail streaming.

The Cuckoo's concentration in the work, coupled with her indifference to observers, was remarkable. Not once did she descend to the ground for material. Not once did she gather material in the tree in which her nest was located. With two exceptions the twigs were all gathered from the same tree. Working thus off and on for an hour or two at a time, the bird completed the nest. The third night the Cuckoo was sitting on the nest at dusk, but after two days she deserted.

About the Notes from A.C. Bent

Notes from A.C. Bent

This Central and South American species was added to our fauna by George B. Sennett (1879), who secured a fine male on May 19, 1878, near Lomita, Tex., while it was "flying about the low bushes in open chaparral. It was very shy, flying in and about the bushes, and was shot on the wing." The only one I have ever seen did not seem at all shy. I was sitting down, quietly watching some Texas sparrows that were hopping around on the ground near me, in some thick brush bordering a resaca near Brownsville, Tex., when one of these curious birds appeared. It seemed more curious than shy, as it moved about slowly in the bushes, looking me over; it remained in my vicinity for some time and I could have shot it easily. It is said to show a preference for thick underbrush in the vicinity of water, or for lightly wooded swamps.

In his proposed work on the birds of the Caribbean lowlands, Alexander F. Skutch devotes two long and very interesting chapters to the home life of the groove-billed ani. He has kindly placed at my disposal his unpublished manuscript and allowed me to quote freely from it. As to its haunts, he writes: "The variety of the habitat of the anis is enormous and their only restriction seems to be that they do not tolerate the forest and are never seen there. They are birds of open country but seem nearly indifferent to its type. In the inhabited districts of the humid coastal regions they are one of the most conspicuous species. Their favorite haunts are bushy pastures, orchards, the lighter second growth, and even lawns and clearings about the native huts. Marshland is as acceptable to them as a well-drained hillside, and they are numerous in such extensive stands of sawgrass as that surrounding the Toloa Lagoon in Honduras, although it is probable that they do not venture far from some outstanding hummock or ridge which supports a few low bushes in which they can roost and nest, in the semidesert regions of the interior, where their associates of the coast lands, if present at all, are as a rule rare and restricted to the moist thickets along the rivers, they are among the most numerous of birds, and live among scattered cacti and acacias as successfully as amid the rankest vegetation of the districts watered by 12 feet of rainfall in the year. In altitude they range upward to 5,000 feet, but are not nearly so numerous in the elevated districts as in the lowlands."

About the Notes from A.C. Bent

The following Bent selection points out a problem that has been around for a long time: the competition between humans and non-human animals for the same food.

In the second paragraph there is an example of anthropomorphism, which is the attributing to non-human animals, the emotions and motivation of humans. To characterize the rattle sound of the kingfisher as laughter towards a hawk that had chased it has no zoological support.

Notes from A.C. Bent

Enemies: The most serious enemies of the kingfisher are the selfish fisherman, who wants all the fish for himself and begrudges the poor bird an honest living, and the proprietor of a trout hatchery, who is unwilling to go to the trouble and expense of screening his pools to protect his fish. The former shoots every kingfisher he can with misguided satisfaction; the latter either shoots or traps any that visit his pools. A small, unbaited, steel trap is set and fastened to the top of a stake or post near the bird's favorite fishing pool; if the trap is so set that the pan is at the highest point, the bird is almost sure to alight on it and is caught. Hundreds of kingfishers are caught and killed in this way along private trout streams, or about trout hatcheries, every year.

The natural enemies of the kingfisher are of no great menace to its welfare. The Cooper's and the sharp-shinned hawks often pursue it, perhaps largely for sport; under the accounts of these two hawks, in a previous volume, will be found references to these attacks and the successful attempts of the kingfisher to escape by diving; it even seems as if the kingfisher enjoyed the sport, judged by its derisive "laughter" at the defeat of the hawk.

About the Notes from A.C. Bent

Notes from A.C. Bent

Food: The food mentioned by Mr. Skutch (MS.) consisted of small minnows. Mr. Simmons (1925) says that this kingfisher is a "business-like little fisherman, perching atop a stick or stake in the water or on a low branch overhanging low water"; it "frequently flies back and forth over the water, hunting for small fish." It's often driven off feeding-grounds by the larger Belted Kingfisher, with which it is sometimes found."

Enemies: The first set of eggs that Mr. Skutch found failed to hatch, as they were destroyed by ants. He writes (MS.): "Opening the burrow, I found it swarming with myriads of small, amber 'fire ants,' a scourge to man and beast alike. Invading the nest, they had worried the birds until they fidgeted on their eggs and cracked them; then they had worked into the cracks and begun to eat the embryos. I had cleaned them out the previous evening, but all to no avail. The nest was completely ruined. That same morning they had attacked and killed three young woodpeckers in their nest in a dead stub standing a few paces from the kingfishers' burrow. In the humid coastal regions, ants are one of the principal enemies, if not actually the chief enemy, of nesting birds. I have found more eggs and nestlings destroyed by them than by all other known agents combined."

Behavior: F. H. Fowler (1903) writes:

On June 9, 1892, my father and I accompanied Dr. A. K. Fisher to Garden Canyon seven miles south of the post. We reached the canyon and were riding up the narrow trail bordered with pines and live oaks, when suddenly a beautiful male trogan flew across the path just ahead of us, and perched on a live oak bush on the other side of the small stream which flows through the canyon. The Doctor tried to approach it, but the noise caused by his passage through the thick brush and over the sliding rocks on the hill side alarmed the bird, which from the first had seemed a trifle uneasy, and it was soon lost to view among the trees down the canyon.

About the Notes from A.C. Bent

Notes from A.C. Bent

Food: Referring to the food of Lewis's woodpecker, Major Bendire (1895) writes:

In summer its food consists mainly of insects of different kinds, such as grasshoppers, large black crickets, ants, beetles, flies, larva of different kinds, as well as of berries, like wild strawberries and raspberries, service berries and salmon berries, acorns, pine seeds, and juniper berries, while in cultivated districts cherries and other small fruits enter into its daily bill of fare. Here, when common, it may occasionally do some little damage in the orchards, but this is fully compensated by the noxious insects it destroys at the same time. In localities where grasshoppers are abundant they live on these pests almost exclusively while they last. Mr. Shelly W. Denton tells me he noticed this Woodpecker gathering numbers of May flies (Ephemera) and sticking them in crevices of pines, generally in trees in which it nested, evidently putting them away for future use, as they lasted but a few days. It is an expert flycatcher, and has an extremely keen vision, sallying forth frequently after some small insect when this is perhaps fully 100 feet from its perch.

On this latter subject, Mr. Rathbun writes to me:

Lewis's woodpecker is an expert at catching insects on the wing. When in this act, its perch is some vantage spot such as the top of a dead tree or a bare limb in the open. Here it sits motionless, except to turn its head from side to side on the lookout for its prey; and when this is seen, the bird glides from its resting place to make a capture. On one occasion for more than an hour, we watched a pair of these woodpeckers seize flying insects, and in that length of time not less than 35 were taken. Through our field glasses we kept a close watch on the birds and soon learned from their actions when an insect was sighted, thus it was easy for us to anticipate its capture, and in not a single instance was a failure made by either of the birds. Once, a light puff of air changed the course of the insect just at the time it was about to be taken, but the woodpecker made a quick turn upward at the same time, dropped its legs straight down, and neatly made the take. When busy catching insects on the wing, this bird leaves its perch by easy wing beats or a long, slow, graceful glide; then, after its prey is caught, rises in its flight and, quickly wheeling, returns to its lookout station.

But, as if not content with hunting insects after the manner of a flycatcher, sometimes this bird mingles with the swallows as they hawk over the ground. On one occasion in summer, as we came to a very open pasture, we noticed numbers of barn and cliff swallows in flight over it after insects, and in company with them was a pair of Lewis's woodpeckers. Back and forth over the meadow flew these dark birds, busy in an attempt to catch flying insects, and their actions as they flew were in marked contrast to those of the graceful swallows. Although we watched the woodpeckers for more than half an hour, throughout that time neither one alighted; and when we left the place both still coursed busily above the field.

About one-third of the food of Lewis's woodpecker consists of acorns. It shares with the California woodpecker the interesting habit of storing acorns, though its method of storing them is quite different, for it seldom, if ever, makes the neat round holes to fit the acorns, so characteristic of the other species; and its stores of acorns are never so extensive, so systematic, or so conspicuous as those of the California woodpecker. Charles W. Michael (1926) writes:

Recently we watched a Lewis Woodpecker making trips back and forth between a Kellogg oak and his home tree, a cottonwood. He was busy storing away his winter supply of acorns. Occasionally he picked a fallen acorn from the ground; more often he flew into the lesser branches of the oak, and hanging like a great black chickadee he plucked the acorn from the cup. With crow-like fiappings, his broad wings carried him back to the dead cottonwood with his prize In his bill. Alighting somewhat below the summit of his tree he would, by a series of flight jumps, come to a certain shattered stub where a fissure formed a vise. Into this he would wedge the acorn.

With the acorn held firmly In place he would set about cutting away the hull, and strong strokes of his bill would soon split away the shell and expose the kernel. But he was not satisfied in merely making the kernel accessible, he must go on with his pounding until he had broken It into several pieces, and then with a piece in his bill he would dive into the air like a gymnast, drop twenty or thirty feet and come with an upward swoop to perch on the trunk of the same tree. A few hitching movements would bring him to a deep crack that opened Into the heart of the tree. Here he would carefully poke away, for future reference, his morsel. Usually the acorn was cut into four parts, involving four such trips, and on the last trip to the vise he would take the empty hull In his bill, and with a jerk of his head, toss it into the air. An examination of the ground beneath the tree disclosed hundreds of empty acorn shells. Holding a watch on the Lewis Woodpecker, we found that he made five trips in five minutes and stored five acorns.

J. Eugene Law (1929) has published another illuminating paper on this subject, which is well worth reading; he describes in considerable detail the woodpeckers' methods in storing the meats of acorns in cracks in poles and indulges in some speculation as to the causes and purposes involved in the habit.

Herbert Brown (1902) found Lewis's woodpeckers quite destructive to pomegranates and quinces, near Tucson, Ariz. On September 30 he counted ten in the pomegranate groves; "they were mostly feeding on pomegranate fruit. They first cut a hole through the hard skin of the fruit and then extract the pulp, leaving nothing but an empty shell." Later, on October 13, he says: "Now that the pomegranate crop has been destroyed they have commenced to eat the quinces, of which there are large quantities. On the tops of some of the bushes I noticed that every quince had been eaten into, one side -of the fruit being generally eaten away."

William E. Sherwood (1927) writes:

On June 16, 1923, while collecting near Imnaha, Wallowa County, Oregon, I frightened a Lewis woodpecker from the top of a fence post where it was evidently having a feast. On top of the post it had left a fresh egg, probably its own; for it was absolutely fresh, of the right size, and unmarked. The shell had been broken into, but the contents not yet extracted.

In a knothole on the side of the post was an eggshell (of the same kind), and a snail shell which had been broken into. Wedged into the cracks of the post were several insects (some of them still alive) of the two species commonly known as "salmon flies" and "trout flies." On the ground at the foot of the post were several snail shells, a green prune (picked into), and several cherry seeds with stems attached.

Johnson A. Neff (1928) has much to say about the economic status of this woodpecker, mainly in Oregon. A few quotations from his paper will serve to show the vast amount of damage to the fruit grower that it does in sections where it is abundant, mainly in summer and fall. He says that Prof. Beal (1911) "mentions one case in Washington wherein the birds tore the paper at the corners of packed boxes of apples left in the orchard over night, picking into every apple within reach, and necessitating the repacking of every box attacked."

S. D. Hill wrote to Mr. Neff:

In some sections and seasons they will destroy carloads of fruit, especially in orchards near timber. I have known them to do 50 percent damage to a pear crop in the Peyton district on upper Rogue River." Jackson Gyger, Ashland, wrote: "In 1924 the loss on Spitz and Delicious apples was about 75 percent, on Newtowns about 15 percent; Bosc and Anion pears about 10 percent. The loss on trees near oak timber was nearly 100 percent. This season (1925) due to hunting them every day the loss was possibly 50 percent less. I bought $18.00 worth of ammunition to combat them this year. One man can not keep them out of a seven acre orchard, as they will work on one end while you are scaring them out of the other.

Mr. Neff goes on to say:

These complaints can not be over-looked, for stomach analyses show only the volume of fruit eaten, not the percentage of fruit damaged per tree, nor the real loss to the orchardist. * * *

In Oregon, although it sometimes becomes a nuisance in the small fruit plantings of various areas, it centers its destructive activities in the Rogue Valley; there it flocks in the greatest abundance. * * *

In this area there can be no question of the objectionable status of the Lewis woodpecker. If the birds would consume each fruit injured, there would be little complaint of their taking the quantity which probably would satisfy them. They are restless and energetic, however, and always attacking fresh fruit, which with one stroke of the bill is ruined for commercial use. If one allows only one bite to each fruit, some of the stomachs studied would have contained the samples of as high as two bushels of fruit In the restricted areas mentioned the Lewis woodpecker is a pest.

This is an amazing account of how many acorns a group of Acorn Woodpeckers could fit on a single oak tree. Acorn Woodpeckers are colonial birds and have been known to collectively store acorns in a tree that they will share during the winter.

carpintero - referring to the Acorn Woodpecker as a carpenter.

Notes from A.C. Bent

In Tecolote Canyon, west of Santa Barbara, there is a giant sycamore which I count one of the handsomest examples of Carpintero's workmanship: an unbroken shaft, at least forty feet high and three feet across the inlaid face, covered with a "solid" mass of acorns totalling, say, some 20,000. Strawberry Valley in the San Jacinto Mountains appears to be a paradise for the California Woodpecker. Here majestic oaks (Quercus californica) alternate with still more majestic pines (Pinus ponderosa), the former for sustenance and the latter for storage, and the doughty "California" is probably the most abundant bird in the valley. The holes of the most enormous pines are methodically riddled with their acorn-carrying niches, and in some of the trees the work is carried through from base to crown. In one such tree I estimated that there were imbedded no less than 50,000 acorns.

About the Notes from A.C. Bent

An interesting account that suggests that different species may work together to form stronger protection by being together, than by being on their own.

Notes from A.C. Bent

Behavior: Writing of the habits of these woodpeckers in the sandhills of North Carolina, Milton P. Skinner (1928) says:

They are seen at times with Chickadees, red-cockaded woodpeckers, Brownheaded Nuthatches, Kinglets and Juncos. And these associations seem to be actual and usual, and not temporary and accidental ones as they are between most birds of different species. The downy woodpeckers are peaceable little fellows but other birds will impose on them. I have seen a yellow-bellied sapsucker and a mob of three or four English Sparrows near Pine Bluff chasing one about. But downy was a fast flier and outflew all his tormentors each time. Their flight is undulating and typical of the woodpecker family. These woodpeckers have one trait of the Brown Creepers: they prefer to work up a tree and fly down to the base of the next one.

About the Notes from A.C. Bent

When I consider the advantage of the Hairy Woodpecker spending time with rough-bark trees over smooth-barked trees, and I remember that it eats mostly insects, I figure that there are a lot more insects to be found in the crevices of the rough barked tree than the smooth barked tree.

Notes from A.C. Bent

Behavior: The hairy woodpecker is a much shier, more retiring bird than the confiding little downy; it is also more active and noisier; it usually will not allow such close approach but will dodge around the trunk of a tree or fly away, if an intruder comes too near, bounding through the air in a series of graceful dips and rebounds. Rex Brasher (1926) followed one for four hours that alighted "on two hundred and eighteen different trees, an average of nearly one a minute! The longest time he remained on one tree was seven minutes. This was a dead chestnut with most of the bark still adhering. By far the larger proportion of the trees were old chestnuts, and under their loosely attached covering he found most successful hunting. Rough-bark species were preferred: chestnuts, oaks, old maples and hickories, about in the order named. Smooth-barked ones received little notice."

Notes from A.C. Bent

Courtship: The courtship of the flicker is a lively and spectacular performance, noisy, full of action, and often ludicrous, as three or more birds of both sexes indulge in their comical dancing, nodding, bowing, and swaying motions, or chase each other around the trunk or through the branches of a tree. From the time of Audubon to the present day, many observers have noted and described the curious antics of this star performer. But I prefer to quote first from some extensive notes recently contributed by Francis H. Allen, as follows: "The courtship of the flicker is an elaborate and somewhat puzzling performance. Two birds face each other on the branch of a tree or cling side by side, though at a little distance apart, on the trunk, and spread their tails and jerk their heads about in a sort of weaving motion, frequently uttering a note that is peculiar to this performance, a wick-up or weekup. The head motion is a series of backward jerks with the bill pointing up at an angle of perhaps 60 degrees and the head at the same time swinging from side to side. Sometimes a short, low wuck is uttered from time to time during the performance. These bouts occur not only between male and female, but frequently between two males or two females.

About the Notes from A.C. Bent

Competition for nesting sites is very intense between different species. There are only so many cavities to go around as the story below demonstrates.

Notes from A.C. Bent

Audubon (1842) relates the following story, as told to him by the Rev. John Bachman: "A pair of pileated woodpeckers had a nest in an old elm tree, in a swamp, which they occupied that year; the next spring early, two blue-birds took possession of it, and there had young. Before these were half grown, the woodpeckers returned to the place, and, despite of the cries and reiterated attacks of the blue-birds, the others took the young, not very gently, as you may imagine, and carried them away to some distance. Next the nest itself was disposed of, the hole cleaned and enlarged, and there they raised a brood. The nest, it is true, was originally their own."

Notes from A.C. Bent

The northern race of the white-headed woodpecker is found in the Cascade Mountains and the Sierra Nevada, from Washington to Kern County, Calif., and eastward into western Idaho and western Nevada.

It is a bird of the pine and fir forests in the mountains, ranging from 4,000 to 9,000 feet during the breeding season, but coming down to lower levels in winter. W. L. Dawson (1923) says: "This woodpecker is essentially a pine-loving species and is, therefore, nearly confined to the slopes of the Sierras and the Transition zones of the southern ranges. Only in winter does it appear at lower levels, and then rarely beyond the pale of the yellow pine. So close is this devotion of bird to tree that the woodpecker's feathers are almost always smeared with pine pitch; and I have found eggs dotted with pitch and soiled to blackness by contact with the sitting bird."

Clarence F. Smith writes to me that he found this woodpecker very common around a camp where he was located from June 25 to July 10, 1935, in Tuolumne County, Calif., in the Transition Zone at an elevation of about 4,000 feet. The camp was at one time a lumbering mill, and there was much dead standing timber nearby. Most of the trees were Pinus ponderosa and Pinus lambertianti.

About the Notes from A.C. Bent

The word, well, in the section below refers to the holes that the sapsuckers typically drill in the trunks of trees so they can eat the sap that comes up from the holes. In one sense they are "sugar wells" just like "oil wells". There is debate on the percentage that sap plays in the diet of the sapsuckers.

Notes from A.C. Bent

Food: The food of the red-breasted sapsucker is much like that of its close relatives in the various group. M. P. Skinner writes to me: "I have found red-breasted sapsuckers drilling on cottonwoods, willows, yellow pines, and lodgepole pines; but all the actual feeding I have seen was on willows. Mr. Michael tells me that these birds work largely on the apple trees that have been planted in various parts of the Yosemite Valley. When a sapsucker is at its wells, it takes a sip now and then, but considerable time is used in watchful guarding, or in driving away intruders or would-be robbers. In the case of such wells as I found on willow stems, I could see no established regularity in arrangement. They looked as if the bark had been irregularly scaled off. In fact, such work may be necessary to secure the inner bark; yet the birds actually took sap at such wells. One had a dozen willow stems on which it drilled and sipped in succession; each one was only a few inches from the next; and the bark of each, both above and below the wells, was worn smooth. This bird went from well to well in regular order, then back to the first well to begin again. Although sap formed the bulk of their food in August, I have seen them also searching the bark for insects during that same month."

About the Notes from A.C. Bent

A very interesting account of the confusion in determining which birds are related to each other. As far as I know this is the only example found in the US of a species where the plumage difference between the male and the female are so great that they were considered different species.

This is an interesting group of people. Cassin, Baird, and Lawrence, each have at least one species of bird named after them: Cassin's Finch, Baird's Sandpiper, and Lawrence's Goldfinch.

"suspicious proximity" means that the two birds were in the same area.

Notes from A.C. Bent

Williamson's sapsucker is not only one of our most unique woodpeckers in its striking coloration, but it has an interesting history. Owing to the radical difference in appearance between the two sexes, they were for some time regarded as two distinct, species. The female was the first to be described by John Cassin (1852, p. 349), based on a specimen collected by John G. Bell in Eldorado County, Calif. Under the name black-breasted woodpecker (Melanerpes thyroideus), Cassin describes and figures (1854) the adult female as the male of the species and says of the female:

"Similar to the male, but with the colors more obscure, and the black of the breast of less extent and not so deep in shade," which is a very fair description of the immature female. The male was discovered and described and figured by Dr. Newberry (1857) under the name Picus williamsonii, based on a specimen collected by him on August 23, 1855, on the shores of Klamath Lake, Oreg. Baird, Cassin, and Lawrence (1860) give a very good description of an adult male, as the male of the species, but say "female with the chin white instead of red," which, of course, is the immature male. Thus we have the adult of each sex regarded as the male of a species, and the young bird of each sex regarded as the female of a species. With careless, or improper, sexing of specimens, such an error might easily occur, but it is remarkable that it remained so long undiscovered. Baird,Cassin, and Lawrence (1860) describe the male as Sphyrapicus williamsonii Baird, Williamson's woodpecker, and the female as Sphyrapicus thyroideus Baird, brown-headed woodpecker. J. G. Cooper (1870), in the Geological Survey of California, edited by Baird, follows the same error but calls the female the round-headed woodpecker. Even Baird, Brewer, and Ridgway, in their history of North American Birds, had not discovered the error, for they use substantially the same nomenclature.

It remained for Henry W. Henshaw (1875) to discover the true relationship of the two supposed species and clear up the previous misunderstanding. He writes: "While near Fort Garland, I obtained abundant proof of the specific identity of the two birds in question; williamsonii being the male of thyroideus. Though led to suspect this, from finding the two birds in suspicious proximity, it was some time before I could procure a pair actually mated. A nest was at length discovered, excavated in the trunk of a live aspen, and both the parent birds were secured as they flew from the hole, having just entered with food for the newly hatched young."

Notes from A.C. Bent

Spring: It is spring in the Transition Zone when in April the yellow-bellied sapsucker passes through on the way from its winter quarters to its breeding ground in the Canadian Zone. If spring is tardy most of the trees may be leafless, but many of them have blossomed, and the sap is running.

At this season the sapsucker is light-hearted and jaunty compared to the sober, quiet bird that visited us the autumn before. The breeding season is near at hand, and if two birds meet they often engage in a sort of game, a precursory courtship, wherein one bird flies at the other in a playful attack; the other eludes the rush of the oncoming bird by a sudden, last-minute retreat: winding around the branch on which it rests, or sliding off into the air. In these pursuits in and out among the branches we are impressed by the agility and grace of the birds and by the easy way they direct their course through the air. They do not appear to impel themselves by strength of wing alone, but, especially in their slanting descents, they let the force of gravity pull them swiftly along, and then, by the impetus of the speed attained, glide upward to a perch. They seem to swing from branch to branch with little effort, slowly opening and closing their wings to guide them on their way. As we watch them we are reminded of trapeze artists in the circus.

But the new sap is running, and the birds quickly tap the supply by drilling into the bark of their favorite trees and drink of the sap as it flows freely from the wounds.

Every spring the birds come to a sturdy yellow birch tree on the Boston Public Garden, a species of tree with which they must be familiar on their breeding grounds in the north. The sap flows plenteously in mid-April from the many punctures that the birds make; it wets a large portion of the trunk of the tree and often drips to the ground from the branches. The birds stand clear of the tree as they feed at the sap wells with only the feet and the tip of the tail touching the bark. The tail is braced against the trunk at an angle of about 45 degrees and the feet reach far forward to grasp the bark opposite the bend of the wing. I have never seen a sapsucker crouch against this wet bark as a downy woodpecker commonly does when digging out a grub: like a cat hunched up lapping a saucer of milk. When a bird wishes to move to a point below where it is perched, it jumps from the tree and floats in the air, then turning, with its wings held out somewhat, dives bead-downward, drifting in an easy, leisurely manner as if moving under water; then, just before alighting, it rights itself. If you come too near, the sapsucker scrambles around to the rear of the limb, and if you step close up to the tree, the bird starts away in free, sweeping curves, like a skater over the ice, the white in the wing flashing out.

Behavior: John H. Flanagan (1911) witnessed a rather remarkable performance by a red-naped sapsucker, such as I had not seen recorded elsewhere. He had chopped out a nest containing two fresh eggs and was intending to leave them for a possible addition to the set, as he had done successfully before, when one of the birds, "both of which remained in sight, flew to the tree, perched a moment upon the edge of the cut hole, then went in, and shortly reappeared with one of the eggs in its beak. It flew to a nearby stub, not more than forty feet from where" he "was sitting, calmly devoured the egg and dropped the empty shell."

About the Notes from A.C. Bent

Cactus Woodpecker is an old name for Ladder-backed Woodpecker. (Dryobates S. cactophilus) is an older scientific name for Ladder-bakced Woodpecker.

The Gilded Flicker mentioned below is now considered a sub-species of the Northern Flicker.

P. pubescens is a reference to the Downy Woodpecker.

Notes from A.C. Bent

The cactus woodpecker ranges, according to the 1931 AOU Check-List, from "central western Texas through New Mexico and Arizona to extreme northeastern Lower California and southeastern California, north to extreme southern Nevada and southwestern Utah, and south to northern Durango." It frequents the deserts, or the borders of the deserts, and the lower slopes of the mountains in the Sonoran Zone, a hot, dry region where there are no trees of any size and where this is about the only species of woodpecker found. We never found it in the giant-cactus, or saguaro, region, where it seemed to be replaced by the noisy Gila woodpecker and Mearns's gilded flicker. W. Leon Dawson (1923) says:

Of course it must not be understood that the Cactus Woodpecker tries to live In the central wastes of the desert; for however much it may forage over the creosote and cholla patches, on occasion, it requires something of more ample girth for a nesting site. Hence its breeding range is confined to the more fruitful upper edges of the Lower Sonoran zone, and to the moister bottoms. In the former situation the dried stalks of the agave and the lesser yucca (whippici), or of the Joshua tree (Yucca arborescena), and the Mobave Yucca offer asylum. In the valley of the Colorado, fearing no rivalry from P. pubescens lunch, the Cactus Woodpecker is able to monopolize the willows which grow so rankly along the lagoons.

Referring to Arizona, Harry S. Swarth (1904) says: "This woodpecker is seldom seen above 5,500 feet, and rarely ventures into the canyons. On the plains below, wherever there is brush or trees, and all along the San Pedro River it is very common, as in fact, I have found it in all similar places I have visited in southern Arizona."

Swarth says elsewhere (1929):

In southeastern Arizona, east of the Santa Rita Mountains, the vast areas of prairie land are for the most part unsuitable to this species. Wherever even a scanty growth of chaparral has found a foothold, though, the Cactus Woodpecker is pretty sure to occur, for it does not require large trees. Along the streams and washes in this same area, as elsewhere, it does frequent the sycamores and other larger growths, but these do not form the preferred habitat. In the lowlands west of the Santa Rita Mountains this woodpecker is in the surroundings that suit it best. It does not frequent the giant cactus (I do not believe that there is a known instance of its nesting in one), but stays nearer the ground, in cholla cactus, creosote bush, catelaw or other lowgrowing vegetation.

Nesting: Major Bendire (1895) writes:

In southern New Mexico and Arizona it nests sometimes in the flowering stems of the agave plant and also in yucca trees, and I have found it nesting on Billito Creek, Arizona, in a small dead willow sapling not over 3½ inches in diameter. The cavity was about 12 feet from the ground and 10 inches in depth, and the entrance hole a trifle over 1½ inches in diameter. This nest was found on June 8, 1872, and contained only two eggs, in which incubation was about one-half advanced; the eggs laid on fine chips. The nesting sites are placed at various distances from the ground, from 3 to 30, usually from 11 to 14 feet. Dead branches of trees or partly decayed ones seem to be preferred to live ones. * * * It nests by preference in mesquite trees, one of our hardest woods, and it must require a long time to chisel out a nesting site in one of these trees. While it is true that the heart is usually more or less decayed, the birds have first to work through an inch or two of solid wood which is almost impervious to a sharp ax.

Mrs. Florence M. Bailey (1928) says that in New Mexico the nests are "from 2 to 30 feet from the ground in holes in mesquite, screw bean, palo verde, hackberry, and China trees, willows, cottonwoods, walnuts, oaks, and other trees, telegraph poles, fence posts, and stalks of agave, yucca, and cactus."
