Like all woodpeckers, the hairy is an expert climber, perfectly at home

on the trunk of a tree, or even on the under side of a branch, where

its strong claws enable it to cling in almost any position or to move

about with astonishing rapidity and skill in any direction. Its stiff

tail feathers act as a prop and help to support it while hammering away

at the bark with its powerful beak. Forbush (1927) says that it “is the

embodiment of sturdy energy and persistent industry. Active, cheerful,

ever busy, its life of arduous toil brings but one reward, a liberal

sustenance. It sometimes spends nearly an hour of hard labor in digging

out a single borer, but commonly reaches the object of its quest in

much less time.”

_Voice._--The ordinary call of the hairy woodpecker is louder and

shriller than that of the downy. Francis H. Allen says, in his

notes, that it bears “about the same relation to it as the solitary

sandpiper’s _peet-weet_ does to that of the spotted sandpiper. I hear

it most frequently from the female. In fact, a female of the species

that visits my place at all times of the year often utters this note

continually, as if calling for a mate or claiming territory, but she

never nests very near.”

Bendire (1895) describes its ordinary note as “a shrill, rattling note,

_triii, triii_;” and again as several loud notes uttered on the wing,

like _huip, huip_. Forbush (1927) calls the ordinary note “a high,

sharp, rather metallic _chink_ or _click_.” Aretas A. Saunders (1929)

says: “The call is a loud ‘keep,’ like that of the downy woodpecker,

but louder. Another call is a loud rattle, suggesting that of the

Kingfisher, but slurring down the scale. Another call, ‘kuweek kuweek

kuweek kuweek,’ is used during the mating season, and suggests the

Flicker’s ‘oweeka.’”

_Field marks._--The hairy woodpecker is a large edition of the downy

woodpecker, a black and white woodpecker, white below and black above,

spotted with white on the wings, and with a broad white stripe down the

center of the back. Only the male has the red patch on the back of the

neck. It can be distinguished from the downy by its much larger size,

its more restless behavior, its relatively longer and larger bill, and

by the lateral tail feathers, which are pure white in the hairy and

somewhat barred with black in the downy.

_Enemies._--B. T. Gault, in his notes from Marshall County, Ill.,

states: “The hairy woodpecker is now a very rare breeder here owing to

the fact that the English sparrow appropriates almost every nest hole

as soon as it is excavated. I once saw one of these sparrows enter the

hole of one of these birds, take a newly hatched bird out in its bill,

flutter for an instant over the water (the nest was in a dead willow

snag standing in the overflowed Illinois River bottoms), and drop the

young bird into the water to drown. It then returned into the nest and

soon appeared with another newly hatched woodpecker in its bill. As it

fluttered over the water for an instant, my gun cracked and the sparrow

died.”

Verdi Burtch (1923) writes: “April 16, 1922, when in a thin wood I

heard a female hairy woodpecker making a great fuss as they do when one

invades the vicinity of their nest. As I neared the place I saw the

nest hole about twenty feet up in an elm stub. About ten feet away,

sitting erect on a limb of another tree, was a red squirrel eating

something that it held in its fore-paws. My 8-power binoculars showed

this to be a naked baby bird, presumably a hairy woodpecker and not

more than two or three days old.”

Mr. Shelley (1933) tells of a pair of hairy woodpeckers that were

twice, in the same season, driven out of their nest by starlings and

their eggs destroyed.

_Fall._--The Hairy woodpecker has often been said to be a permanent

resident on its breeding grounds, but this is not strictly true. The

species may be present all through the year over much of its range, but

there is evidence to indicate a general southward movement in fall; the

individuals seen in winter are probably not the same as those seen in

summer. Moreover, there is a noticeable increase in numbers in certain

localities in winter.

Lewis O. Shelley has sent me some full notes on the migration of hairy

woodpeckers, as he has observed it near East Westmoreland, N. H., from

which I quote as follows: “For four years I have watched, in the autumn

months, passing hairies that go through, some dropping down into the

valley to feed as they go along, but others passing over the valley

from hill to hill (2 miles) without stopping. In passing through,

they traverse in general the same route each year. They come from an

eastern and continue on in a western direction at an oblique angle

to the Connecticut River, which they must cross in the vicinity of

Brattleboro, Vt.

“These migrants usually appear here late in August or early in

September and continue to arrive at irregular intervals until late in

October. It is common for one, or two, rarely more, to pass together;

but such occurrences have happened, as on October 24, 1934, when,

beginning soon after noon and lasting until four o’clock, the birds

continued to pass through. At least 12 were seen as I walked up a

roadway parallel to their course; and other moving birds were heard. It

was also noticed that they kept spaced 40 to 50 yards apart, keeping

abreast of one another, traversing in a leisurely manner; and as they

approached a rock maple woods, the tendency was to close in like

passing through the neck of a bottle and, once through the woods, again

to spread out. Their progress was rather fast; and they fed little,

if at all. They often called, as though to locate each other, since

they were keeping about 40 yards apart, as was easily noted when they

crossed pasture and mowing land.

“I followed and watched in particular a male that continued keeping

along ahead of me. He repeatedly crossed the road in a zigzag manner.

Climbing to the top of a fence post or stump, he made lengthy

observations, probably noting the progress of the other birds, and

often answered their ringing calls. He, as well as the others, gave the

appearance of a stranger in a new environment, truly a migrant. I noted

how low the birds were passing, quite frequently flying not over 2 feet

from the ground over open spaces, where long, bounding flights were

made.”

L. McI. Terrill told Mr. Forbush (1927) that the few local breeding

birds disappear from the vicinity of Montreal early in autumn, and

others, in a very noticeable wave, appear toward the end of October or

early in November.

_Winter._--Aside from the regular migratory movements, the hairy

woodpecker is much more given to wandering about in winter. It is apt

to forsake its woodland haunts and travel about in search of food,

coming frequently into the farmer’s orchard, into rural villages, and

even into thickly settled communities in some of our larger cities.

Here it often joins the merry parties at our winter feeding stations,

feeding readily on the suet or scraps of meat provided for our

insect-eating birds; and here the smaller birds show due respect for

its larger size, or perhaps for its formidable beak, and it is usually

allowed to eat alone. It seems to be a solitary bird at this season,

for we seldom see more than one at a time. I find it not so constant

and regular a visitor to my feeding station as the downy woodpecker and

some other birds; it probably wanders about more.

Mr. Forbush (1927) writes: “During the inclement season it is said

to require a sheltered place in which to sleep and, like the downy

woodpecker, to excavate a hole in a tree for a sleeping chamber, but

there is evidence that it does not always seek such shelter, as the

late Charles E. Bailey and myself watched one for several winter

evenings in a grove, clinging upright against a tree trunk in the usual

woodpecker position. Night after night, the bird was there at dusk,

remained there until dark, and was there also at daybreak each morning

in precisely the same place.”

Joseph J. Hickey tells me that, around the lower Hudson River Valley

in winter, woodpeckers obtain much of their food by deliberately

scaling the bark off trees in search for their insect food. The Arctic

three-toed woodpeckers work mainly on pines and hemlocks, but the

hairies appear to confine their work to the hemlocks, using the same

methods as the three-toed.

DISTRIBUTION

_Range._--Northern and Central America; not regularly migratory.

The range of the hairy woodpecker extends =north= to Alaska (Kenai

Peninsula, Fairbanks, and Fort Egbert); Yukon (Forty Mile, Fort

Reliance, and Macmillan River); Mackenzie (Fort Wrigley, Lake Hardisty,

and Fort Resolution); northern Saskatchewan (mouth of the Charlot River

and Poplar Point); northern Manitoba (Grand Rapids, probably Fort

Churchill, and probably York Factory); Ontario (Hat Island and Cobalt);

Quebec (Blue Sea Lake, Quebec City, Godbout, Eskimo Bay, and Anticosti

Island); and Newfoundland (Nicholsville and Raleigh). From this point

the range extends =southward= along the Atlantic coast to southern

Florida (Eau Gallie); the western Bahama Islands (Great Bahama, Abaco,

and Andros); and Panama (Boquete). The =southern= boundary of the range

extends westward from Panama (Boquete); Nicaragua (San Rafael); western

Guatemala (Tecpam); Chiapas (San Cristobal); to Guerrero (Chilpancingo

and Omilteme). From this point, =northward= through the mountains of

western Mexico, northern Baja California (Sierra San Pedro Martir

and Sierra Juarez); and the coastal districts of California, Oregon,

Washington, and British Columbia, to Alaska (Chilkoot, Chitina Moraine,

and the Kenai Peninsula).

As outlined, the range is for the entire species, which has, however,

been so divided that no less than 13 subspecies are currently

recognized as occupying the range north of Mexico, while still others

occur in Central American countries. The typical eastern hairy

woodpecker (_D. v. villosus_), occurs in the Eastern United States

and southern Canada west to Manitoba, North Dakota, and Colorado

and south to North Caralina and central Texas. The northern hairy

woodpecker (_D. v. septentrionalis_) occupies the zone to the north,

from southeastern Quebec, northwestward to western Mackenzie, Yukon,

and central Alaska. The Newfoundland woodpecker (_D. v. terraenovae_)

is found only on the island of that name. The southern hairy woodpecker

(_D. v. auduboni_) occupies the southeastern part of the range from

Missouri, Illinois, and western Virginia south to southeastern Texas

and southern Florida. The Sitka hairy woodpecker (_D. v. sitkensis_) is

found in southeastern Alaska and northern British Columbia. The Queen

Charlotte woodpecker (_D. v. picoideus_) is found only on the group

of islands of that name off the coast of British Columbia. Harris’s

woodpecker (_D. v. harrisi_) occupies the coastal regions of southern

British Columbia south to northwestern California. Cabanis’s woodpecker

(_D. v. hyloscopus_) is confined to certain coastal and mountain areas

of California, chiefly in the southern part. The Lower California hairy

woodpecker (_D. v. scrippsae_) is restricted to the Sierra Juarez and

the Sierra San Pedro Martir of Baja California. The Modoc woodpecker

(_D. v. orius_) is found in the Sierra Nevada of central California

north to Oregon and Washington and east to Nevada. The Rocky Mountain

hairy woodpecker (_D. v. monticola_) is found through the Rocky

Mountain region from central British Columbia south to northern New

Mexico and east (in winter) to western South Dakota and Nebraska. The

white-breasted woodpecker (_D. v. leucothorectis_) is found chiefly

in Arizona and New Mexico but also east to central Texas and north

to southern Utah. The Chihuahua woodpecker (_D. v. icastus_) occurs

principally in western Mexico but occurs also in southern Arizona and

southwestern New Mexico.

_Migration._--As stated above, the hairy woodpeckers are generally

nonmigratory and may be found in midwinter even in the northern parts

of their range, as Alaska, Mackenzie (Fort Simpson), and Manitoba

(Aweme, Minnedosa, and Roseau River). Nevertheless, some individuals

are given to a certain amount of wandering during the winter months,

which explains the occasional records of some subspecies far outside

of their normal range. There also is more or less vertical migration

in the mountainous regions of the north and west, the birds descending

into the lower valleys during the winter season. This is noted

particularly in the Rocky Mountain form, which in winter has been taken

east to Nebraska and South Dakota.

Despite the fact that during the past 18 years several hundred

individuals of this species have been marked with numbered bands, and

many have been subsequently recaptured, there is no evidence that any

of these moved at any time more than a few miles from the point of

banding.

_Egg dates._--British Columbia: 8 records, April 27 to June 24.

California: 43 records, March 23 to June 21; 22 records, April 28

to May 29, indicating the height of the season.

Colorado: 10 records, May 5 to June 18.

Florida: 18 records, April 10 to May 16; 9 records, April 22 to 28.

Illinois: 8 records, May 1 to 23.

Iowa: 8 records, April 21 to May 15.

Labrador: 5 records, May 26 to 30.

Massachusetts: 17 records, May 1 to June 5; 9 records, May 10 to 19.

Ontario: 8 records, May 6 to June 16.

DRYOBATES VILLOSUS SEPTENTRIONALIS (Nuttall)

NORTHERN HAIRY WOODPECKER

HABITS

This large northern race of the hairy woodpecker inhabits the Canadian

Zone of northern North America, north almost to the limit of trees,

from central Alaska and northern Canada southward. In the eastern

portions of southern Canada it intergrades with typical _villosus_, and

in northwestern Montana with _monticola_, where the ranges of these

races meet. Specimens have been taken as far north as Fort Simpson, on

the Mackenzie River, in latitude 62° N., and at Fort Reliance, on the

upper Yukon River, Alaska, in about latitude 66° N. It may occur as

a straggler farther north, where it can find sufficient tree growth,

but it is said to be rare north of latitude 56° N., and apparently

it does not reach the Arctic coast or the coast of Bering Sea. It is

a decidedly larger bird than typical _villosus_, the white markings

average rather larger, and the white is purer. In the southern portion

of its range, where it begins to intergrade with _villosus_, these

characters are, of course, less pronounced and many individuals are

difficult to name.

Living in a region over much of which coniferous forests predominate,

this woodpecker frequents and breeds in this type of forest. Winton and

Donald Weydemeyer (1928) say that it is an abundant permanent resident

in Lincoln County, Mont., where it intergrades with _monticola_. They

also say:

In the valleys it is most numerous, during summer,

in forests containing a large percentage stand of

western larch (_Larix occidentalis_). The next trees

in attractiveness seem to be Douglas fir (_Pseudotsuga

taxifolia_), western yellow pine (_Pinus ponderosa_), and

Engelmann spruce (_Picea engelmanni_), in the order named.

In the Hudsonian zone it frequents trees of white-bark pine

(_Pinus albicaulis_) and alpine larch (_Larix lyallii_).

The species is noticeably rare or absent in forests

containing nearly pure stands of western white pine (_Pinus

monticola_), arborvitae (_Thuja plicata_), or lodgepole

pine (_Pinus contorta_), except where the woods have been

logged or injured by fire.

_Nesting._--The same observers say: “In Lincoln County this species

uses a wide variety of nesting sites. Of eight nests included in our

records, three were in live aspens; one in a live cottonwood; one in a

live larch; one in a dead larch, one in a dead Douglas fir; and one in

a woodpecker nesting box.”

Ernest Thompson Seton (1890) found a nest in a tall poplar tree about

30 feet from the ground, in Manitoba; the hole was about a foot deep,

3 inches wide inside and 2 inches at the entrance. John Macoun (1909)

quotes Rev. C. J. Young as saying: “Most of the nests I have seen have

been in wet places or near water, and almost all were in white ash

trees, from thirty to fifty feet from the ground. Two nests were in elm

trees and one in a telegraph pole by the roadside not more than ten

feet from the ground.”

Roderick MacFarlane (1908) writes: “On the 6th of May, 1885, Mr. Reid

discovered a nest in a hole in a dry standing poplar tree near Fort

Providence. There were eight eggs therein, and the parent was seen

and shot. * * * At Fort St. James, Stuart’s Lake, on the 25th of May,

1889, a native hunter found a nest holding four fresh eggs in a similar

position. Both parents in this instance were also observed near by and

shot. On 4th June, in the same locality, an Indian girl brought us

four eggs. * * * The nest was found in a hole in a dry pine tree, at a

height of several feet above the ground.”

Henry Mousley (1916) says that near Hatley, Quebec, “as a rule the nest

hole is somewhat high up but on one occasion I found one which was only

three feet above the ground in a birch stub, containing four eggs, the

entrance hole being two inches in diameter, extreme depth eleven inches

and average width two and three quarters inches.”

P. B. Philipp and B. S. Bowdish (1919), referring to northern New

Brunswick, say: “A nest with young was found in a dead maple stub in

a burnt barren, on May 29, 1917. On May 30 of the same year another

nest about fifteen feet up in a dead maple stub in a similar situation,

contained four eggs, very slightly incubated. On June 9, 1917, a third

nest in a cedar telephone pole beside a public road was examined. It

was at a height of about nine feet; cavity 14½ inches deep; entrance 2⅛

inches in height by 2¼ inches in width. This nest contained four nearly

fresh eggs.”

_Eggs._--The northern hairy woodpecker lays three to five eggs; the

eight eggs mentioned above by MacFarlane may have been the product

of two females or eggs of the boreal flicker; in the latter case the

collector may have shot the wrong parent. The eggs are like those

of the eastern hairy woodpecker but average slightly larger. The

measurements of 41 eggs average 25.39 by 20.10 millimeters; the eggs

showing the four extremes measure =28.45= by 22.10, 27.43 by =22.35=,

and =21.5= by =16.6= millimeters.

The plumage changes, food, behavior, voice, and other habits apparently

do not differ materially from those of its southern relative. It is

said to be a permanent resident throughout its range, but there is

probably some southward migration or wandering from at least the

northern portion of its range and perhaps from the southern parts also.

That some individuals remain far north in winter is shown by the fact

that the Fort Simpson specimen was taken on December 29, 1860. The

Weydemeyers (1928) say that during winter, in northwestern Montana,

“this woodpecker is commonly found in mixed broad-leaf and conifer

associations along streams, but it is most abundant at that season in

the larch woods of the valleys.”

DRYOBATES VILLOSUS AUDUBONI (Swainson)

SOUTHERN HAIRY WOODPECKER

PLATE 5

HABITS

In the Lower Austral Zone of the South Atlantic and Gulf States we find

this small race of the hairy woodpecker. In addition to being decidedly

smaller than its northern relative, the white of the under parts is

less pure, and the white markings of the upper parts are somewhat

smaller.

Arthur H. Howell (1932) says of its haunts in Florida: “The southern

hairy woodpecker, though not particularly shy, prefers the wilder

sections for its home. It occurs in a variety of situations--the open

pine forests, oak hammocks, and the hardwoods of the deep river swamps.

The birds are of a rather solitary disposition, and rarely is more than

a single bird or a pair found near together.”

_Nesting._--Mr. Howell (1932) says that “the nests are located 12 to 45

feet from the ground in holes excavated in dead oaks or willow stubs,

or in cypresses growing on the edge of a swamp.” S. A. Grimes (1932)

says: “A nest thirty feet up in a live cypress near Eastport [Florida]

held three eggs on April 13. Two well feathered young were found in

a hole fifteen feet up in a dead sweet gum in southern Duval County

on May 13. A nest eight feet up in a pine stub in northern St. Johns

County contained three heavily incubated eggs on May 11.”

Arthur T. Wayne (1910) says that in South Carolina “the nest is very

hard to find; indeed I have found but six nests, two which contained

eggs, and four which contained young. I have known this species to

excavate a hole and raise a brood in a limb of a living live oak tree,

but it generally excavates its hole in a dead tree and at a great

height. A set of three fresh eggs was taken April 7, 1898, from a hole

40 feet from the ground in a dead pine. This hole was 14 inches deep.

The young remain in the hole for more than a month after they are

hatched.”

Harold H. Bailey (1913) says that in Virginia “dead stubs of gum and

poplar treetops seem to be their favorite location for a nesting site,

varying from 25 to 60 feet up, the cavity from eight to twelve inches

deep. They are one of our earliest breeding birds, the drilling of the

nesting cavity beginning the last week in March, and by April 10th to

15th finds a full complement or set of eggs, numbering from four to

six.”

J. G. Suthard writes to me of a nest he found near Madisonville, Ky.

The cavity was “excavated in a dead crab apple stub in open woodland.

Only the female was observed excavating the hole and caring for the

eggs, which proved to be infertile. No male was ever observed near the

nesting stub, though it was carefully observed.” M. G. Vaiden tells me

of a nest 9 feet up in a chinaberry tree in a yard at Rosedale, Miss.,

and another that was 23 feet up in a pecan tree and 3 feet out in a

dead snag.

_Eggs._--The southern hairy woodpecker is said to lay three to six

eggs. The latter number must be unusual, as the set generally consists

of three or four eggs. The eggs are scarcely distinguishable from

those of other hairy woodpeckers, though they average somewhat smaller

than those of the more northern races. The measurements of 42 eggs

average 21.29 by 18.29 millimeters; the eggs showing the four extremes

measure =26.1= by 19.2, 25.8 by =19.8=, =21= by 19, and 23.8 by =16.6=

millimeters.

_Food._--Major Bendire (1895) says that this subspecies seems to be

fonder of fruit and berries than are the northern races and that “the

young are fed largely on figs.” Audubon (1842) says that in the salt

marshes about the mouths of the Mississippi “it alights against the

stalks of the largest and tallest reeds, and perforates them as it is

wont to bore into trees. * * * I have often observed it clinging to the

stalks of the sugar-cane, boring them, and apparently greatly enjoying

the sweet juices of that plant; and when I have seen it, in severe

winter weather, attempting to bore the dried stalks of maize, I have

thought it expected to find in them something equally pleasing to its

taste.”

Milton P. Skinner (1928) says of these birds, in the sandhills of North

Carolina: “In winter the hairy woodpeckers vary their diet of insects

with various berries and dried wild fruits. They are particularly fond

of the small black berries of the sour gum (_Nyssa sylvatica_). Soon

after the early frosts the birds flock to these swamp trees and feast

as long as the berries last.”

The main food supply of this and other woodpeckers consists of insects

and their larvae, which are obtained by searching in the crevices in

the bark of whatever trees are available, or drilling into the trunks

and branches to find the grubs. Mr. Skinner (1928) saw one working on

“a charred and dead stub of a shrub oak. Here it worked steadily for

fifteen minutes pulling out small white grubs and borers. It drove its

bill for three or four strokes up under a bit of bark and then pried

the bark off with its bill as a lever. Then it attacked the semi-rotten

wood so uncovered, directly. It did not seem to work so fast as a downy

woodpecker, but then it was so busy eating grubs that it did not have

to dig much.”

_Behavior._--The same observer says:
