Page 287 454b. Lower California Flycatcher. Myiarchus cinerascens pertinax. Phœbe. 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. Buffy. 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. White. 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.

PHOEBE ON NEST.
Page 289 457-458. 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. White. 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. White. 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.

 Olive-sided Flycatcher. 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. Creamy white. 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.
Page 291 460. Coues's Flycatcher. Myiochanes pertinax pallidiventris. Range.--Western Mexico, breeding north to central Arizona. Cream color. 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. Wood Pewee. Range.--North America, east of the Plains and north to the southern parts of the British Provinces. Winters south of the United States. Cream color. 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.

NEST AND EGGS OF WOOD PEWEE.
Page 293 Yellow-bellied Flycatcher.
Acadian Flycatcher. 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. Creamy white. 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. Creamy white. 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.

 464--466. 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. Buffy. 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. Creamy white. 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 Least Flycatcher. 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. White. 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. 462--469--469.1. White. 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. White. 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.

 Vermillion Flycatcher. 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. Buff. 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.
