Part 29

The Alder Flycatcher will be seen in low growth along streams or in swamps, often actually among alders. Its sides are yellowish, but the belly is always white. The song of this species, which is usually delivered from a prominent and sometimes high perch, may be written becky-weer, and is different from any other flycatcher song, save, perhaps that of the Olive-sided. Its nest is a compact structure, built in the alders, 2 to 3 feet from the ground, usually in a swamp. The three or four eggs are white, sparsely spotted with brown. The Alder Flycatcher is found chiefly in the more northerly counties as a summer resident, from early May to September.

LEAST FLYCATCHER; CHEBEC Empidonax minimus (W. M. and S. F. Baird)

The Least Flycatcher is a bird of open aspen copses or orchards. Its energetic che-bec, which is given with a violent toss of the head, is always characteristic and is responsible for its common name. Look for the bird during migration in May and in September. As a summer resident it occurs chiefly in the more northern counties, where it builds its deep nest in the crotch of some low tree. The eggs, 3 or 4 in number, are pure white. Feathers are often used in the nest, which is made of vegetable fiber and hair.

HORNED LARK Otocoris alpestris alpestris (Linnæus)

This northern relative of our Prairie Horned Lark visits Pennsylvania occasionally in winter, especially in the northern counties. It is a larger, more reddish bird, and the line above the eye is distinctly yellow, sometimes quite colorful.

PRAIRIE HORNED LARK Otocoris alpestris praticola Henshaw

Other Name.—Shore Lark.

Description.—Larger than an English Sparrow; a bird of the ground, with straight toe-nails, the hind one very long. Adult male: Patch on forepart of crown with lateral lines leading to two tiny tufts or horns on nape, patch in front of and below eye, and another on upper breast, black; forehead and line above eye whitish, sometimes very faintly tinged with yellow; throat pale yellow; back of head and upperparts pale grayish brown mixed with reddish brown on neck, back, and wings; middle tail-feathers brown, the other feathers blackish, the outer vanes of the outer feathers white; lower breast and belly whitish, suffused with pinkish brown on sides and flanks; bill, feet, and eyes black. Female and immature: Similar, but duller. Young birds in their first plumage are much spotted, with pale yellowish above, and with blackish below. Length: A little over 7 inches.

Range in Pennsylvania.—Local permanent resident, sometimes quite common, and found only in the opener sections, on bald hilltops or in wide fields in agricultural districts.

Nest.—A cup in the ground lined with grasses, plant-down, and other vegetable material. Eggs: 3 to 5, greenish white, heavily marked with grayish brown, sometimes with a wreath of heavier spots around larger end. The nest is always placed in a wide-open field, sometimes on a bare hilltop. It is built very early in the season, sometimes in early or mid-March, while snow is still on the ground.

In the windy, open fields or on treeless hilltops, this demure and dull-colored bird lives. As he walks or runs among the short grass, twittering in a companionable way, standing still for a moment to survey his surroundings, then wandering off again, little is noted to remind us of the glorious courtship song which this bird of the ground gives during early spring, and for which he should be as famous as the English Skylark. Mounting upward from the clods, he finally reaches a far height, where he pours out his melodious, tinkling music, minute after minute, sweeping about in wide circles, or steadily flying into the wind. Thirty or forty times he may give his song, then becoming tired of his performance, downward he drops to the earth in long, graceful sweeps to alight unconcernedly. He sometimes sings from the ground or from a fence-post.

Horned Larks are given to flocking together in the winter, and when snow covers the ground they sometimes come into the farmyards, or congregate along roads, where they eat horse-manure or waste grain. Look for the black facial markings of these plain brown birds, and remember that they will be found only in open country.

BLUE JAY Cyanocitta cristata bromia Oberholser

Description.—Larger than Robin; sexes similar, both with prominent crest; nostril covered with tuft of feathers. Head, crest, and back grayish blue; forehead and a noticeable collar across lower throat, ear-coverts, and back of crest, black; region about eye whitish; throat and underparts grayish white, darkest on sides; wings and tail bright turquoise-blue, the greater coverts, secondaries, and tertials tipped broadly with white, and all of the feathers barred strikingly with black on their exposed surface; tail-feathers barred with black, the outer ones tipped noticeably with white; feet and bill black; eyes dark brown. Length: About 12 inches.

Range in Pennsylvania.—We should expect the Blue Jay to be a permanent resident in Pennsylvania wherever it is found. It occurs the year round, notably in the southwestern and southern counties, and is usually a summer resident and early spring and mid-fall migrant from March 20 to November 1; as a summer bird it is somewhat local in distribution.

Nest.—A bulky mass of twigs, rootlets, and weed-stalks, rather well made and neatly cupped, placed from 10 to 30 feet from the ground, usually in a more or less open situation and often in a conifer. Eggs: 3 to 6, pale gray green or greenish gray, heavily marked with dull and indefinite brown and gray spots.

The Blue Jay’s colors and manners are unmistakable. As he flies, the white-tipped outer tail-feathers and secondaries show plainly; as he perches, his crest is prominent. But when the bird student essays to identify the Blue Jay from call-notes alone there may be trouble, for this bright creature not only has a considerable vocabulary of his own but also imitates other birds extremely well. He can reproduce the scream of a Red-shouldered Hawk so faithfully that small birds of the vicinity drop into silence for an instant. More than once this cry has misled me. As a rule, he screams peer, peer in a dominant, harsh voice, or gives violin-like, squeaky calls, the pattern and musical intent of which are known only to himself.

He is a confirmed nest-robber and is not protected by law in Pennsylvania. While it is true that he eats the eggs and young of smaller birds, yet he has some food habits in his favor, and at worst is a handsome villain.

The nest is defended valiantly by the parents. I once climbed to a Blue Jay’s nest and took the last remaining young one. As I started to descend I felt a sharp blow on my forehead. When I reached the ground my face was lined with blood; the parent bird had punctured my skin with her beak.

In fall and winter, Blue Jays are very fond of beechnuts and acorns. At the feeding-counter they often choose peanuts if these are to be found. Their hearty manner and brilliant colors make them an attractive addition to any flock of bird-neighbors, in spite of their objectionable traits.

NORTHERN RAVEN Corvus corax principalis Ridgway

Description.—Much larger than a Crow; bill and feet very strong and heavy; feathers of throat long and pointed, not rounded. Entire plumage black, glossed with steel-blue and pale greenish and purplish. Length: About 24 inches. Wingspread about four feet.

Range in Pennsylvania.—A rare permanent resident, found only in the wildest mountain gorges, chiefly in the central counties.

Nest.—A very large and bulky affair, deeply cupped like a Crow’s, usually placed in an inaccessible niche on a cliff or high in a tree. It is made of twigs and branches and is lined with moss, hair, grape-vine bark, and rootlets. Eggs: 3 to 6, usually pale bluish or bluish green, spotted with brown, olive, and gray.

Ravens might easily pass for Crows, were not their cracked, raucous voices to echo solemnly through the gorges which they inhabit. Looking up we may see the great black birds circling through the sky like hawks; we may be near enough to note that the tail is not rounded as in the Crow, but wedge-shaped, the middle feathers being noticeably the longest. When a Raven does not soar, nor croak, he appears much like a Crow, and identification ought to be either from notes, or flight, or from direct comparison with Crows. These smaller cousins, incidentally, mob the Raven with as much gusto as they exhibit in attacking an owl.

CROW Corvus brachyrhynchos brachyrhynchos Brehm

Description.—Black, glossed with bluish and purplish, underparts duller in appearance. The Crow is probably our best-known bird. Length: 19 inches.

Range in Pennsylvania.—In southeastern counties the Crow occurs the year round, and during winter in great flocks; elsewhere it is chiefly absent in winter, returning in late February or early March, and remaining until December. It is widely distributed and abundant as a summer resident.
