Part 19

This species is similar to the last but is considerably paler. They are common in some localities, nesting in holes in trees or stumps, often those deserted by Woodpeckers. Their eggs are like those of the last but average paler. Data.--Corpus Christi, Texas, May 10, 1899. Nest in hole in telegraph pole; made of red cow hair, feathers and leaves. 4 eggs. Collector, Frank B. Armstrong.

454. ASH-THROATED FLYCATCHER. _Myiarchus cinerascens cinerascens._

Range.--North America, west of the Plains and south of Canada.

Similar to the others of the genus but grayish brown above and with the underparts much paler, the throat and breast being nearly white. Like the others they nest in cavities in trees, either natural or ones made by Woodpeckers. Their four to five eggs are lighter in color than those of crinitus but cannot be distinguished from those of the Mexican Crested Flycatcher.

454b. LOWER CALIFORNIA FLYCATCHER. _Myiarchus cinerascens pertinax._

Range.--Lower California.

This sub-species is similar to Nutting Flycatcher but paler below and grayish above.

455a. OLIVACEOUS FLYCATCHER. _Myiarchus lawrencei olivascens._

Range.--Western Mexico, north to southern Arizona.

This is the smallest of the genus found in the United States, being but 7 inches in length. Except for size it is similar to _crinitus_ but with very little, if any, rusty brown on tail, except for a slight edging on the outer web. Their nesting sites are the same as those chosen by the other Crested Flycatcher, but their eggs appear to have but little of the scratchy appearance of the other members. They are pale buffy, speckled and spotted with brown and lilac; size .80 × .60. Data.--Toluca, Mexico, May 20, 1895. Nest of brown hair and feathers, in hole in tree in woods. Collector, Fred T. Francis.

456. PHŒBE.. _Sayornis phœbe._

Range.--North America, east of the Rockies and north to Nova Scotia.

These very common, grayish colored birds are very often known as "Bridge Birds" because of the frequency with which they construct their nests under bridges and arches; they also build in crevices in ledges or among the hanging roots near the tops of embankments, and on the rafters or beams of old buildings. The nests are made of mud, moss and grass, lined with feathers. The four or five eggs measure .75 × .55. Occasionally, eggs will be found that have a few minute spots of reddish brown. Freak situations in which to locate their nests are often chosen by these birds, such as the brake beam of a freight car, in the crevices of old wells, hen houses, etc. The birds are one of the most useful that we have; being very active and continually on the alert for insects and beetles that constitute their whole bill of fare.

457. Say's Phœbe. _Sayornis sayus._

Range.--Western United States, breeding from southern United States, north to the Arctic regions, and from Kansas and Wisconsin westward. Winters in Mexico.

This bird is slightly larger than the last (7.5 inches long), and is rusty brown color on the belly and lower breast. Like the eastern Phœbes they are one of the earliest birds to return in the spring and are abundant in the greater parts of their range. Like the latter, they often raise two broods a season, one in April and another in July. Their nests are generally placed on narrow shelves and crevices of ledges, but they also nest as commonly about houses and farms as does the eastern bird. The nests are made of weeds, mosses, fibres and wool, and are quite flat. They lay four or five white eggs. Size .78 x .58.

458. BLACK PHŒBE. _Sayornis nigricans._

Range.--Mexico and north in summer into the bordering States.

This species is of the size of the last but is blackish (darkest on the head and breast), with a white belly and under tail coverts, the latter streaked with dusky. Their habits and nesting habits are the same as those of the eastern Phœbe, they building their nests of mud, moss, weeds and feathers on ledges or about buildings, and generally close to or in the vicinity of water. They breed during April or May, laying four or five white eggs which cannot be distinguished from those of the common Phœbe. Size .75 x .55.

458a. WESTERN BLACK PHŒBE. _Sayornis nigricans semiatra._

Range.--Pacific Coast of Mexico and the United States, breeding north to Oregon.

This variety differs from the last in having the under tail coverts pure white. Its nesting habits are precisely the same and the eggs indistinguishable.

459. OLIVE-SIDED FLYCATCHER. _Nuttallornis borealis._

Range.--Whole of North America, breeding from the Middle States and California northward, and in the Rockies, south to Mexico; winters south of the United States.

These Flycatchers are nowhere abundant, and in some parts of the country, especially in the middle portion, they are very rare. They breed very locally and generally not more than one pair in any locality. In New England, I have always found them nesting in company with Parula Warblers, in dead coniferous swamps in which the branches are covered with long pendant moss. Their nests are placed high up in the trees, generally above fifty feet from the ground, and on small horizontal limbs; they are made of small twigs and rootlets, lined with finer rootlets and moss, and are very flat and shallow; as they are generally made to match the surrounding, they are one of the most difficult nests to find. They lay three or four cream colored eggs which are spotted with reddish brown and lilac, chiefly about the large end. Size .85 x .65. Data.--Lake Quinsigamond, Massachusetts, June 12, 1897. Nest of twigs and moss, about 60 feet above the ground, in a dead pine tree in center of a large wet swamp. Nest could not be seen from the ground, and was found by watching the birds.

460. COUES'S FLYCATCHER. _Myiochanes pertinax pallidiventris._

Range.--Western Mexico, breeding north to central Arizona.

This Flycatcher builds one of the most artistic nests created by feathered creatures. It bears some resemblance on the exterior to that of the next species, but it is much more firmly made, and the walls are usually higher, making a very deeply cupped interior. The outside of the nest is made of fibres, cobwebs, catkins, etc., firmly felted together and ornamented with green lichens to match the limb upon which it is saddled. The interior is heavily lined with dried, yellowish grasses, making a very strong contrast to the exterior. They are fairly abundant birds in the ranges of southern Arizona, where they nest generally during June. They lay three eggs of a rich creamy color, spotted and blotched, chiefly about the larger end, with reddish brown and lilac gray. Size .95 x .61. Data.--Huachuca Mts., Arizona, July 8, 1897. 3 eggs. Nest in a yellow pine about 60 feet up and near the extremity of a long slender limb. Elevation 7000 feet. Collector, O. W. Howard.

461. WOOD PEWEE. _Myiochanes virens._

Range.--North America, east of the Plains and north to the southern parts of the British Provinces. Winters south of the United States.

This is one of the best known and one of the most common frequenters of open woods, where all summer long its pleasing notes may be heard, resembling "Pee-a-wee" or sometimes only two syllables "pee-wee." They nest on horizontal limbs at elevations of six feet or over, making handsome nests of plant fibres and fine grasses, covered on the exterior with lichens; they are quite shallow and very much resembles a small knot on the limb of the tree. They lay three or four eggs of a cream color spotted in a wreath about the large end, with reddish brown and lavender; size .80 x .55. Data.--Torrington, Conn., June 16, 1890. Nest of fibres covered with lichens, saddled on the branch of an oak tree near roadside. Collector, John Gath.

462. WESTERN WOOD PEWEE. _Myiochanes richardsoni richardsoni._

Range.--Western United States from the Plains to the Pacific, and from Manitoba southward, wintering south of the United States.

The nesting habits of this bird are the same as those of the eastern Pewee, but their nests are more strongly built and generally deeper, and without the outside ornamentation of lichens. They are saddled upon horizontal branches, like those of the preceding, as a rule, but are also said to have been found in upright crotches like those of the Least Flycatcher. Their three or four eggs cannot be distinguished from those of the eastern Wood Pewee.

462a. LARGE-BILLED WOOD PEWEE. _Myiochanes richardsoni peninsulæ._

Range.--This species which differs from the last only slightly, as is indicated by the name, inhabits the peninsula of Lower California; its nesting habits and eggs will not differ from those of the other Pewees.

463. YELLOW-BELLIED FLYCATCHER. _Empidonax flaviventris._

Range.--North America, east of the Plains and north to Labrador; winters south of the United States.

This species is slightly larger than the Least Flycatcher and is more yellowish above and below, the breast being quite bright. While common in some districts it is quite shy and frequents thickly wooded regions, where it is not very often seen. They nest near or on the ground among rocks or roots of fallen trees, chiefly in swampy places; the nests are made in bunches of moss, hollowed out and lined with very fine grasses. Their four eggs are creamy or buffy white, spotted and speckled about the larger end with reddish brown and gray; size .68 × .51.

464. WESTERN FLYCATCHER. _Empidonax difficilis difficilis._

Range.--Western North America, from the Rocky Mountain region to the Pacific, and north to Alaska; winters chiefly south of the United States.

This Flycatcher, which is similar to the last, nests in similar locations as well as in many others, such as crevices and fissures in rocks, holes in banks, cavities in trees, rafters in buildings, etc. The nests are variously made, but consist chiefly of fine grasses, weeds and fibres. The eggs are as a rule similar to those of the last species and cannot be distinguished.

Page 294

464a. SAN LUCAS FLYCATCHER. _Empidonax difficilis cineritius._

Range.--Lower California.

This species is similar to, but duller in plumage than the Western Flycatcher. Their nesting habits do not probably vary from those of the latter.

465. ACADIAN FLYCATCHER. _Empidonax virescens._

Range.--Eastern United States, breeding from the Gulf to southern New England, and in the Mississippi Valley to Manitoba.

This species is very pale below and greenish yellow on the back. They are among the latest of the migrants to reach our borders and arrive in the Middle States about the latter part of May, when they are quite common. They build semi-pensile nests in the forks of bushes or overhanging branches at heights of from four to twenty feet, the nests being made of rootlets, fibres, fine grasses, etc., and partially suspended from the branch; they are quite shallow and loosely constructed and often appear more like a bunch of debris deposited in the fork by the wind than like the creation of a bird. Their three or four eggs are buffy, spotted or specked with brown; size .75 × .55.

466. TRAILL'S FLYCATCHER. _Empidonax trailli trailli._

Range.--Western North America, from the Mississippi Valley to the Pacific; winters south of the United States.

This species is very similar to the next, but the back is said to be more brownish. They are common and nest abundantly in thickets and low scrubby woods, usually placing the nest at a low elevation, preferably in a clump of willows; the nests are made of fine strips of bark, plant fibres, and very fine rootlets being woven about and firmly fastened in upright crotches. Their eggs, which are laid in June, are buffy white, specked and spotted, chiefly at the large end, with brownish; size .70 × .54.

Page 295

466a. ALDER FLYCATCHER. _Empidonax trailli alnorum._

Range.--United States, east of the Mississippi and north to New Brunswick.

The only difference between this and the preceding variety is in the more greenish upper parts. They are quite abundant in the breeding season from New England and northern New York northward, frequenting, to a great extent, alder thickets bordering streams. Their nests and eggs do not differ appreciably from those of the western variety of Traill Flycatcher.

467. LEAST FLYCATCHER. _Empidonax minimus._

Range.--North America, east of the Rockies and north to the interior of Canada, wintering south of the United States.

These little birds (5.5 inches long) are common about houses and orchards on the outskirts of cities, and on the edges of forests or open woods. They are very frequently known by the name of Chebec from their continually uttered note. In nearly all instances, the nests are placed in upright forks at elevations varying from four to twenty-four feet from the ground. The nests are made chiefly of plant fibres, fine grasses, string, cobwebs, etc., and the three to five eggs are pale creamy white; size .65 × .50.

468. HAMMOND'S FLYCATCHER. _Empidonax hammondi._

Range.--North America, west of the Rockies and from British Columbia southward, wintering south of the United States.

This western representative of the Least Flycatcher is less abundant and more shy, but has the same nesting habits as the eastern birds, placing its nests either in upright crotches or, more rarely, upon horizontal branches at a low elevation. The eggs cannot be distinguished from those of the last species.

469. WRIGHT'S FLYCATCHER. _Empidonax wrighti._

Range.--Western United States, breeding from the Mexican border to Oregon and wintering south of the United States.

A very similar bird to the last but whiter below. It is a much more abundant species than the last and is found breeding in open woods and thickets on all the ranges. The nests are built like those of the Least Flycatcher and nearly always are found in the crotch of trees or bushes at a low elevation; their nests, like those of the two preceding species, bear a strong resemblance to those of the Yellow Warblers which are found in the same localities and locations. The eggs are pale creamy white, four in number and measure .68 × .52.

Page 296

469.1. GRAY FLYCATCHER. _Empidonax griseus._

Range.--Lower California, north to southern California.

This is a slightly larger species than the preceding and is grayish above and paler below, with little or no tinge of brownish or yellow. As far as I can learn its eggs have not yet been taken.

470a. BUFF-BREASTED FLYCATCHER. _Empidonax fulvifrons pygmæus._

Range.--Western Mexico, north to southern New Mexico and Arizona.

This small bird, which is but 4.75 inches in length, is brownish gray above and brownish buff below. It is not a common species anywhere, but is known to nest during June or July, on high mountain ranges, saddling its nest of fibres, covered with lichens, on horizontal boughs at quite an elevation from the ground. The eggs are pale buffy white, unspotted, and measure .60 × .50.

471. VERMILLION FLYCATCHER. _Pyrocephalus rubinus mexicanus._

Range.--Mexico, north regularly to southern Texas, Arizona and New Mexico.

This is one of the most gaudy attired of all North American birds, being brownish gray on the back, wings and tail, and having a bright vermillion crown, crest and underparts. They are quite common in southern Texas, but far more abundant in the southern parts of Arizona. Their habits do not differ from those of other Flycatchers, they living almost exclusively upon insects. The majority of their nests can not be distinguished from those of the Wood Pewee, being covered with lichens and saddled upon limbs in a similar manner, but some lack the mossy ornamentation. Their three or four eggs are buffy, boldly blotched with dark brown and lavender, chiefly in a wreath about the middle of the egg; size .70 × .50. Data.--San Pedro River, Arizona, June 10, 1899. Nest in the fork of a willow about 20 feet above the stream. Collector, O. W. Howard.

472. BEARDLESS FLYCATCHER. _Camptostoma imberbe._

Range.--Central America; north casually to the Lower Rio Grande in Texas.

This strange little Flycatcher, several specimens of which have been taken in the vicinity of Lomita, Texas, is but 4.5 inches in length, grayish in color and has a short bill, the upper mandible of which is curved. It has all the habits peculiar to Flycatchers. Their eggs have not as yet been found as far as I can learn.

LARKS. Family ALAUDIDÆ

473. SKYLARK. _Alauda arvensis._

Range.--Old World, straggling casually to Greenland and Bermuda.

This noted foreigner has been imported and liberated a number of times in this country, but apparently is not able to thrive here, a fact which will not cause much regret when we remember the experiment with the English Sparrow. They are abundant in Europe and Great Britain where they nest on the ground in cultivated fields or meadows, laying from three to five grayish eggs, marked with brown, drab and lavender.

474. HORNED LARK. _Otocoris alpestris alpestris._

Range.--Eastern North America, breeding in Labrador and about Hudson Bay; winters in eastern United States south to Carolina.

This variety of this much sub-divided species is 7.5 inches in length, has brownish gray upper parts and is white below with black patches on the breast and below the eye, yellowish throat and small black ear tufts. The various subspecies are all marked alike, their distinction being based upon slight differences in size, variations in the shade of the back, or the greater or less intensity of the yellowish throat and superciliary stripe. The nesting habits of all the varieties are the same and the eggs differ only in the shade of the ground color, this variation among the eggs of the same variety being so great that an egg cannot be identified without knowing the locality in which it was taken. The present variety build their nests on the ground generally under tufts of grass or in hollows in the moss which is found in their breeding range, making them of dried grasses and generally lining them with feathers. The eggs are grayish with a slight greenish tinge, and are specked and spotted over the whole surface with drab, brownish and dark lavender. The eggs of this and the next variety average considerably larger than those of the more southerly distributed varieties; size .92 × .65.

474a. PALLID HORNED LARK. _Otocoris alpestris arcticola._

Range.--Breeds in Alaska and winters south to Oregon and Montana.

This is the largest of the Horned Larks and has the throat white, with no trace of yellow. Its nest is built in similar locations and the eggs are like those of the preceding species.

Page 298

474b. PRAIRIE HORNED LARK. _Otocoris alpestris praticola._

Range.--Breeds in the Mississippi Valley from Illinois north to Manitoba and east to the Middle States; winters south to Carolina and Texas.

This sub-species is considerably smaller than the Horned Lark, and the throat is paler yellow, while the line over the eye and the forehead is white. They are the most abundant and have the most extended range of any of the better known species. In the Mississippi Valley, where they are of the most common of the nesting birds, they build on the ground in meadows or cultivated fields, and very often in cornfields; the nests are made of grasses and lined with horse hairs or feathers, and placed in slight hollows generally under a tuft of grass or sods. They raise two broods a season and sometimes three, laying the first set of eggs in March and another in June or July. The three or four eggs have an olive buff ground and are thickly sprinkled with drab and lavender; size .83 × .60.

474c. DESERT HORNED LARK. _Otocoris alpestris leucolæma._

Range.--Plains of western United States, east of the Rockies and west of Kansas and Dakota; breeds north to Alberta, and winters south to Mexico, Texas and southern California.

This species is like _praticola_, but paler on the back; nest and eggs the same.

474d. TEXAS HORNED LARK. _Otocoris alpestris giraudi._

Range.--Coast of southeastern Texas.

A pale variety like _leucolæma_, but smaller; throat bright yellow, and breast tinged with yellow. Nest and eggs like those of the others.

474e. CALIFORNIA HORNED LARK. _Otocoris alpestris actia._

Range.--Lower California and southern California.

This bird is similar to the last but the yellow areas are brighter, and the nape and back are ruddy.

474f. RUDDY HORNED LARK. _Otocoris alpestris rubea._

Ranges--Sacramento Valley, California.

This variety has the yellow areas brighter than in any other and the back and nape are more ruddy. The eggs cannot be distinguished from those of the others.

Page 299

474g. STREAKED HORNED LARK. _Otocoris alpestris strigata._

Range.--Northwestern United States (Washington, Oregon and northern California).

Similar to the last, but with the back broadly streaked with black, the ruddy less intense and the underparts tinged with yellowish.

474h. SCORCHED HORNED LARK. _Otocoris alpestris adusta._

Range.--Western Mexico, north in summer to southern Arizona.

This variety has the back and nape nearly a uniform pinkish ruddy with but little streaking.

474i. DUSKY HORNED LARK. _Otocoris alpestris merrilli._

Range.--Northwestern United States and southern British Columbia, wintering south to central California.

Similar to _praticola_ but slightly darker above.

474j. SONORA HORNED LARK. _Otocoris alpestris pallida._

Range.--Gulf coast of northern Lower California.

The upperparts of this variety are very pale pinkish brown.

474k. HOYT'S HORNED LARK. _Otocoris alpestris hoyti._

Range.--Interior of British America, west of Hudson Bay and east of Alaska, south in winter in the interior of the United States to Kansas.

Much larger than the last; equal in size and similar to _articola_ but with the throat yellowish and the upperparts darker and brighter.

474l. MONTEZUMA HORNED LARK. _Otocoris alpestris occidentalis._

Range.--Western New Mexico and eastern Arizona, south in winter to northern Mexico.

This variety has the upperparts pale brownish and not streaked; throat and forehead yellowish.

474m. ISLAND HORNED LARK. _Otocoris alpestris insularis._
