Part 35
_Nesting._--Capt. H. L. Harllee writes to me that southern flickers raise two broods in a season in South Carolina and are not very particular as to their nesting sites. They nest in holes of their own excavation in dead trees of many species, 3 to 100 feet from the ground, either in thick woods or in a lone dead tree in an open cultivated field; they also nest in natural cavities in trees. He found one pair of these birds nesting in a hole made by fire in an old burned-out stump; the cavity was about two feet deep and eight inches in diameter; “the opening was slightly arched over with grass growing around it; a small quantity of pine straw was the only lining.”
Arthur H. Howell (1932) says: “The nests are placed in pines, oaks, cabbage palms, or other trees, at heights varying from a few feet to 60 feet above the ground. At Ponce Park, in May, 1925, I observed a Flicker using a hole in a palmetto pile under the dock on the shore of the Halifax River, only 2 feet above the salt water at high tide. Nicholson found a nest 12 inches above the ground in a sawed-off stump of a palmetto on a ditch bank.”
Alexander Sprunt, Jr. (1931), mentions a concentration of hole-nesting birds in a tree in a yard in Beaufort, S. C.; the tree measured only 20 feet in height and contained nests of two pairs of flickers, and one nest each of crested flycatcher, screech owl, and downy woodpecker. “All five cavities were contained in a radius of ten feet, and four were within six feet of each other.”
A. F. Ganier (1926) writes:
While in the suburbs of Chattanooga, Tennessee, last spring, I noticed a Flicker engaged in what appeared to be a hopeless task in the way of nest excavation. An iron water tank, supported by steel columns forty feet high, was fed by a large iron pipe through its bottom, and, to keep this pipe from freezing in winter, it had been encased with a plank shaft two feet square that was filled with cedar sawdust. Our friend _Colaptes auratus_ had evidently sounded the boards, and, sensing easy digging, had drilled a hole in the middle of one side about thirty feet up. When espied, he was enthusiastically pitching out quantities of sawdust, which I presume caved in about as fast as he dug, but during the half hour I was engaged near by there was no let up in the work. About a month later I was again in the vicinity and made it a point to go by the tank. On the ground below the hole was at least a bushel of sawdust, and in a few minutes I had the pleasure of seeing a Flicker enter the hole with food in its mouth, presumably to feed the young that had come to reward his perseverance.
_Eggs._--The southern flicker lays five to ten eggs, ordinarily, but shares with its northern relative its reputation as a prolific egg layer; it will continue to lay again and again after being robbed, as many as 30 or 40 eggs and often three or four sets. The eggs are similar to those of the northern flicker, except for a slight difference in size. The measurements of 44 eggs from South Carolina average 28.57 by 22.01 millimeters; the eggs showing the four extremes measure =30.15= by =24.56= and =24.13= by =20.32= millimeters. These seem to run larger than eggs from farther north.
In all other respects, the habits of the southern flicker are similar to those of the species elsewhere, with due allowance for the difference in environment. Two items of interest, however, are worth quoting. Charles R. Stockard (1904) writes from Mississippi:
On April 18 a burrow of a Flicker containing only one fresh egg was found. The egg was not disturbed. When visiting the nest again on April 28 a flying squirrel was found in possession. On my arrival the bird was at the entrance of the burrow peering in at the intruder. It was supposed that the squirrel was eating the eggs, but on examining the nest it was found to contain one spoilt egg. The squirrel had then probably been in possession for the ten days since the nest was observed, so the bird had been unable to enter and lay. * * * The Flicker must then have remained about her nest for this length of time, and as soon as the squirrel was removed she again took charge. On visiting the nest May 5, seven days later, it contained seven fresh eggs and the old one that had been left. * * * This was undoubtedly a case of discontinuous laying unless she had dropped her eggs on the ground while the squirrel was occupying the nest.
Mrs. Sanford Duncan (1932), of Nashville, Tenn., tells an interesting story of a flicker that was captured by a bullsnake. She heard a great commotion among the birds in her yard and went out to investigate the cause of the excitement. “The Flickers were leading the battle, dashing and darting at a bundle of something on the ground. Closer inspection with field glasses showed it was a snake, all tied up in a curious knot. He was too big for me to attack with the hoe I had, so I shot into the ‘bundle’ with a shotgun. As if by magic the snake flung himself into the air and fell, straightened out, over five feet long, and disclosed a full-grown Flicker that he had wrapped himself around many times. The Flicker was still alive, but died very shortly, probably from the gunshot that killed the bullsnake.”
Lester W. Smith writes to me that he watched a southern flicker digging white grubs out of a lawn and killing them by repeated blows and shaking; meantime a loggerhead shrike was attempting to rob the flicker of its prey.
DISTRIBUTION
_Range._--North America, chiefly east of the Rocky Mountains, and from the limit of trees south to the Gulf coast.
_Breeding range._--The breeding range of the flicker extends =north= to Alaska (Circle); northwestern Mackenzie (probably Fort McPherson, Fort Anderson, McVicar Bay, Fort Rae, and Hill Island Lake); northern Saskatchewan (Reindeer Lake); northern Manitoba (probably Lake Du Brochet and Fort Churchill); Ontario (Lac Seul and probably Moose Factory); Quebec (probably Fort George, probably Lake Mistassini, Godbout, and Mingan Island); and Labrador (Cartwright). From this northeastern point the range extends =southward= through Newfoundland, along the Atlantic coast to Key West, Fla. The =southern= limits of nesting are the Gulf coasts of Florida and Alabama, thence in the interior to Louisiana (St. Francisville and Genoa); and Oklahoma (Okmulgee and Norman). =West= to Oklahoma (Norman); central Kansas (Harper, Hay, and Stockton); Nebraska (Red Cloud, Alda, and Chadron); eastern Wyoming (Midwest and Newcastle); Montana (Terry, Fairview, and Great Falls); Alberta (Morrin, Henry House, and Lesser Slave Lake); northwestern British Columbia (Telegraph Creek and Atlin); Yukon (Caribou Crossing and Selkirk); and eastern Alaska (Circle). This species, more or less crossed with the red-shafted flicker (_Colaptes c. collaris_), also is found occasionally in eastern Colorado (Hallvale, Denver, and Fort Morgan).
_Winter range._--During the winter season the flicker is found with more or less regularity =north= to southeastern South Dakota (Yankton, Vermillion, and Sioux Falls); southern Minnesota (Hutchinson and Minneapolis); southern Wisconsin (North Freedom and Milwaukee); southern Michigan (Kalamazoo, Jackson, Ann Arbor, and Detroit); southern Ontario (Plover Mills, Hamilton, and Toronto); New York (Rochester, Syracuse, and Rhinebeck); and rarely Maine (Waterville). From this point it is found =south= along the Atlantic coast to southern Florida (St. Lucie and Fort Myers). The southern limits of the winter range are found on the Gulf coast from Florida (Fort Myers) to Texas (Brownsville). =West= to Texas (Brownsville, San Antonio, San Angelo, and Abilene); central Oklahoma (Norman, Oklahoma City, and Tonkawa); Kansas (Wichita and rarely Hay); Nebraska (Red Cloud and North Loup); and southeastern South Dakota (Yankton). It also has been taken or observed at this season north to southern Saskatchewan (Eastend); Quebec (Montreal); New Brunswick (St. John); and Nova Scotia (Bridgetown).
The range as outlined is for the entire species, of which two subspecies are currently recognized. The typical form, known as the southern flicker (_C. a. auratus_), is found from southern Florida and Texas north to southeastern Kansas, southeastern Missouri, southern Illinois and Indiana, and North Carolina. It probably is nonmigratory. The rest of the range is occupied by the northern flicker (_C. a. luteus_).
_Spring migration._--Early dates of arrival in regions north of the winter range as outlined, are: Nova Scotia--Wolfville, March 26; Halifax, April 7. New Brunswick--Scotch Lake, April 5; Grand Manan, April 12. Quebec--Quebec City, April 27; Godbout, May 2; Paradise, June 5. North Dakota--Fargo, March 29; Charlson, March 30; Grand Forks, April 2. Manitoba--Winnipeg, March 30; Alexander, April 14; Raeburn, April 15. Saskatchewan--Eastend, April 3; McLean, April 3. Wyoming--Cheyenne, April 7; Laramie, April 12. Montana--Great Falls, April I; Terry, April 4; Jackson, April 14. Alberta--Banff, April 4; Flagstaff, April 13; Edmonton, April 17. Mackenzie--Fort Simpson, May 4; Fort Reliance, May 2. Alaska--Fairbanks, April 25; Fort Yukon, May 1.
_Fall migration._--Late dates of fall departure are: Alaska,--Wrangell, October 11; Craig, October 21. Mackenzie--near McVicar Bay, September 10; Great Slave Lake, September 11; Fort Simpson, October 16. Alberta--Lac La Biche, September 25; Glenevis, October 2; Calgary, October 10. Montana--Bozeman, September 24; Saskatchewan--Eastend, October 14. Manitoba--Alexander, October 22; Aweme, October 27. North Dakota--Arlington, October 19; Argusville, October 21; Fargo, October 21. Northern Michigan--Sault Ste. Marie, October 24. Quebec--Montreal, November 25. New Brunswick--St. John, November 5; Scotch Lake, November 22. Nova Scotia--Wolfville, November 19.
The records of flickers that have been banded and subsequently recovered throw much light upon the migrations of this species. In the files of the Biological Survey there are long series of cases where birds banded at their nests in the northern parts of the breeding range (Alberta, Saskatchewan, Manitoba, Michigan, New York, and Massachusetts) have returned to the same point one to four years later. These birds probably all belonged to the subspecies _luteus_. Similarly, similar data also are available for areas (Missouri, Kentucky, Tennessee, and Florida) within the range of _C. a. auratus_, which probably is nonmigratory.
Definite migrations of individual banded birds are indicated by the records of flickers banded in Saskatchewan and recovered in Iowa, Oklahoma, and Texas; banded in Missouri and recovered in Texas; banded in Iowa and recovered in Louisiana; banded in South Dakota and recovered in Arkansas and Oklahoma (4); banded in Illinois and recovered in Kentucky, Tennessee, Missouri, Arkansas (2), and Louisiana (3); banded in Indiana and recovered in Mississippi; banded in Michigan and recovered in Arkansas and Louisiana; banded in Ohio and recovered in Alabama and Mississippi; banded in Pennsylvania and recovered in Georgia; and banded in Nova Scotia and recovered in North Carolina.
_Casual records._--In southern British Columbia a specimen was collected at Sumas on April 8, 1903, and two were seen at Vernon on December 26, 1906; a specimen was taken at Orcas Island, Wash., on October 15, 1907; one was collected at Blaine, Oreg., on November 3, 1921; and one was taken at Cliff Spring, Nev., on September 29, 1931. There are several records for California as follows: Furnace Creek, April 12, 1917; St. Geronimo, December 18, 1893, and January 14, 1895; Point Lobos, December 14, 1934; Los Angeles, February 20, 1901; San Diego, December 4, 1931; and Eldridge, January 4, 1913.
At least four occurrences well north of the breeding range in Alaska have been recorded: St. George Island, fall of 1904; Cape Etolin, September 14, 1927; Wainwright, a specimen in 1924; and Cape Halkett, in the fall of 1927.
A specimen was collected on Okpatok Island in Hudson Strait in October 1882, one was taken in Sandwich Bay in August 1908, and a specimen has been reported from Cape Wolstenholme on the Ungava Peninsula. The species also has been recorded from Bermuda where at least one specimen was collected in 1871.
_Egg dates._--Arctic America: 6 records, June 3 to 16. Florida: 18 records, March 25 to July 18; 9 records, April 16 to May 18, indicating the height of the season. Illinois: 22 records, April 30 to May 30; 11 records, May 13 to 21. Michigan: 16 records, April 17 to June 24; 8 records, May 12 to 30.

NORTHERN FLICKER
PLATE 36
HABITS
I can remember as clearly as if it were only yesterday my boyish, enthusiastic admiration for this beautiful bird, though it was between 50 or 60 years ago that my father first showed me a freshly killed flicker. I was simply entranced with the softly blended browns, the red crescent on the head, the black crescent and bold spotting on the breast, and, above all, with the golden glow in the wings and tail. Few birds combine such charming colors and pleasing contrasts. I have never lost my admiration for it, and still consider it one of nature’s gems.
It, and its close relative, the red-shafted flicker, together are widely distributed over nearly all the wooded regions of North America. Consequently it is widely known and over most of its range is a common and familiar species. Its prominence and popularity are attested by the long list of vernacular names by which it is locally known. Franklin L. Burns (1900), in his monograph of the species, lists 123 such names; and later he adds nine more, bringing the list up to 132 names. These are far too many to be quoted here, and many of them are “very local or very slight orthographical or cacographical variants.” I have always loved our local name “partridge woodpecker,” suggestive of my boyhood days, when flickers, meadowlarks, and robins were considered legitimate game. But now the name yellow-shafted flicker seems appropriate to distinguish it, from the red-shafted flicker.
The haunts of the flicker are almost everywhere in open country or lightly wooded regions; it can hardly be called a forest-loving species, though I have often found it nesting in more or less extensive deciduous woods; its favorite haunts during the summer seem to be in the rural districts among the farms, orchards, and scattered woodlots; it seems to be at home, also, in villages and small towns, and even in some of the smaller cities, where spacious grounds and gardens provide suitable surroundings. In fall and winter it is more apt to wander about in open woodlands, fields, and meadows or seek shelter in coniferous woods or swamps.
_Spring._--Although many flickers remain all winter in the Northern States, there is a decided spring migration of the great bulk of northern-bred birds that have wintered in the Southern States. These birds gather in flocks during the late winter, and the northward movement starts with the first mild weather, the migration being largely performed during the night. Mr. Burns (1900) says that at Berwyn, Pa., the forerunners, consisting of solitary old males, appear “as early as Feb. 2 or as late as April 6, according to the promises of the season, correlating in a measure with the date at which the first frog is heard peeping. * * *
“It becomes common soon after the hardy willow has unfolded its leaves, and about the time the fragrant spicewood blossoms, when the ants, spiders and beetles become active once more, and just in the height of the arbutus season. The northward movement is far from being steady or regular, being largely governed by weather conditions; Mr. Burns calculates from his mass of data that the average distance traveled daily is about 12 miles, varying according to season and weather conditions from 7 to 48 miles per night. It is absolutely certain that it does not move steadily night after night, but only as the weather permits or necessitates and its physical condition allows.”
Flickers often migrate in companies of considerable size, in loose, scattered flocks, noisy and active, flying from tree to tree and calling excitedly. Their arrival is announced by the loud challenge-call, given from the top of some tall tree, _wicker_, _wicker_, _wicker_, or _wake-up_, _wake-up_, _wake-up_, as the male challenges his rivals or invites his prospective mate to join him in courtship. This, one of the most welcome sounds of early spring, is indeed a call to “wake up,” for all nature is awakening, buds are swelling on the trees, verdure is appearing in the woods and fields, the early flowers are beginning to blossom, the hylas are peeping in the warming pools, insects are becoming active, and the songs of the early birds announce that spring is here. Another spring sound soon strikes our ears, a loud, far-reaching, vibrant sound, the long, almost continuous roll of the flicker’s drumming, another challenge-call, a preliminary of the courtship performance; at frequent intervals, often repeated over a long period in early morning, he beats his loud tattoo on some hollow, resonant limb.
_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 _week-up_. The head motion is a series of backward jerks with the bill pointing up at an angle of perhaps 60° 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.
“In April 1934, for more than a week I saw a trio of flickers about my house. Invariably the two females went through courtship antics together, while the male fed on the ground nearby, apparently completely indifferent to them. One of the females was much more active than the other, which usually kept a stiff pose with head drawn in, only occasionally responding with feeble head-waggings. At no time did the active female use any other display than the head-wagging, and there was never any suggestion of combat or intimidation.
“A year later, 1935, the flickers near my house behaved differently. In the afternoon of April 24, the two males were singing loudly and frequently in the woods, about an eighth of a mile away and at some distance apart. By singing I mean, of course, the prolonged laughing call of _wick-wick-wick_, etc. Presently they stopped singing, and one flew toward the other, stopping about halfway. Very soon the other joined him, and a long period of posturing and _wick-up_-ing ensued. Both birds had the black mustaches of the male. The posturing was the regular ‘weaving’ of the head and the fanning of the tail. The notes, after the first at least, were much subdued in tone. There were frequent intervals of quiet. The birds kept close together most of the time, often with heads only two or three inches apart, or perhaps less. They flitted about frequently, sometimes clinging to the trunk of an oak, sometimes perched on a horizontal branch, and once or twice they alighted on the stems of underbrush. After a long period of posturing, they met in a momentary tilt, and presently there was another clash after more posturing, then a third clash, and after that they separated. The same bird was the aggressor in at least two of the clashes. As often in such encounters, the attacked bird stood his ground and the attacker veered off. It was very mild warfare, if it was really serious at all.
“Two days after the bout of the two males, I saw two females engaged in the dance in one of our pear trees. It lasted only a few minutes, and I heard no notes. Not long after the dance of the two females a prolonged ‘sexual flight’ took place. It lasted five or ten minutes, as nearly as I could tell, with a few short intervals of resting. I could at no time determine the sexes of the two birds thus engaged, but occasionally a snatch of faint song was heard (_wick-wick-wick_), and I assume that they were male and female. They flew rather slowly and kept only a few feet apart. It was evident that the spacing was intentional and that the pursuer made no attempt to catch up with the other. The flight covered a territory of several acres. It was a graceful and interesting performance.
“I supposed at the time that this sexual flight indicated that the affair was completed, but later that afternoon I several times saw a male and two females together, the females posturing and _wick-up_-ing, the male motionless. The females showed no enmity toward each other and did not face each other, as the males of two days before did. They kept rather farther apart. At one time a second male appeared and stayed about for a time, but he disappeared, apparently without becoming a serious factor in the situation.
“Three days later a pair of flickers, male and female, were feeding peacefully together on the lawn in the morning and in the afternoon, and I judged that the marital arrangements of at least two of my flickers had been completed.”
More active courtship on the part of a female flicker is thus described in some notes from Lewis O. Shelley: “On April 24, coincident with a male flicker’s message from the elm stub, a female and a second male appeared. All three were later in the cherry tree by our garden, perched on branches some three feet apart. The female took the initiative in the following activities and, perched crosswise of the branch, often bobbed and ducked up and down, then crosswise of the branch jerked to left, right, left, right, head cocked erect and with tail fully spread. At times the males, less actively, did likewise, but for the most part perched noncommittally, silent and still, giving but few calls. At one time, after the female had displayed intermittently several times, and when the males had been still for some five minutes, she sidled up to the nearest male and again displayed with much wing-fluttering and tail-spreading and sidewise twitchings; then the same to the other male who flew when her actions of bobbing and bowing face to face commenced. Not to be outdone, or so affronted, she flew after him, then the second male followed.”
C. W. Leister (1919) noticed an aerial courtship evolution of the flicker, of which he says: “When first noticed, he was about fifty feet from the ground and ascending in peculiar, bumpy, and jerky spirals. This was maintained until a height of about 350-400 feet was reached, when, after a short pause, a reverse of practically the same performance was gone through. The Flicker (_Colaptes auratus luteus_), for as such he was identified by this time, then alighted in a cherry tree, just above a female that we had previously failed to notice, and completed the performance by going through his more familiar courting antics.”
