ARKANSAW FLYCATCHER.
Muscicapa verticalis, Bonap.
PLATE CCCLIX. Male and Female.
This species extends its range from the mouth of the Columbia River, across our continent, to the shores of the Gulf of Mexico; but how far north it may proceed is as yet unknown. On the 10th of April 1837, whilst on Cayo Island, in the Bay of Mexico, I found a specimen of this bird dead at the door of a deserted house, which had recently been occupied by some salt-makers. From its freshness I supposed that it had sought refuge in the house on the preceding evening, which had been very cold for the season. Birds of several other species we also found dead on the beaches. The individual thus met with was emaciated, probably in consequence of a long journey and scanty fare; but I was not the less pleased with it, as it afforded me the means of taking measurements of a species not previously described in full. In my possession are some remarkably fine skins, from Dr Townsend’s collection, which differ considerably from the figure given by Bonaparte, who first described the species. So nearly allied is it to the Green-crested Flycatcher, M. crinita, that after finding the dead bird, my son and I, seeing many individuals of that species on the trees about the house mentioned, shot several of them, supposing them, to be the same. We are indebted to the lamented Thomas Say for the introduction of the Arkansaw Flycatcher into our Fauna. Mr Nuttall has supplied me with an account of its manners.
“We first met with this bold and querulous species, early in July, in the scanty woods which border the north-west branch of the Platte, within the range of the Rocky Mountains; and from thence we saw them to the forests of the Columbia and the Wahlamet, as well as in all parts of Upper California, to latitude 32°. They are remarkably noisy and quarrelsome with each other, and in the time of incubation, like the King Bird, suffer nothing of the bird kind to approach them without exhibiting their predilection for battle and dispute. About the middle of June, in the dark swamped forests of the Wahlamet, we every day heard the discordant clicking warble of this bird, somewhat like tsh’k, tsh’k, tshivait, sounding almost like the creaking of a rusty door-hinge, somewhat in the manner of the King Bird, with a blending of the notes of the Blackbird or Common Grakle. Although I saw these birds residing in the woods of the Columbia, and near the St Diego in Upper California, I have not been able to find the nest, which is probably made in low thickets, where it would be consequently easily overlooked. In the Rocky Mountains they do not probably breed before midsummer, as they are still together in noisy quarrelsome bands until the middle of June.”
Dr Townsend’s notice respecting it is as follows: “This is the Chlow-ish-pil of the Chinooks. It is numerous along the banks of the Platte, particularly in the vicinity of trees and bushes. It is found also, though not so abundantly, across the whole range of the Rocky Mountains; and among the banks of the Columbia to the ocean, it is a very common species. Its voice is much more musical than is usual with birds of its genus, and its motions are remarkably quick and graceful. Its flight is often long sustained, and like the Common King Bird, with which it associates, it is frequently seen to rest in the air, maintaining its position for a considerable time. The males are wonderfully belligerent, fighting almost constantly, and with great fury, and their loud notes of anger and defiance remind one strongly of the discordant grating and creaking of a rusty door hinge. The Indians of the Columbia accuse him of a propensity to destroy the young, and eat the eggs of other birds.”

Adult Male. Plate CCCLIX. Fig. 1.
Bill rather long, stout, tapering, broader than high, unless toward the end. Upper mandible with its dorsal outline straight and declinate, until at the tip, where it is deflected, the ridge narrow, the sides convex, the edges sharp, with a slight notch close to the very narrow tip. Lower mandible with the angle short and broad, the dorsal line ascending and very slightly convex, the ridge broad and flat at the base, the sides convex, the edges sharp, the tip acute. The gape-line almost straight. Nostrils basal, elliptical, partly covered by the bristly feathers.
Head rather large; neck short; body slender. Feet very short; tarsus slender, compressed, with six anterior scutella, which are so large below as almost to meet behind; toes free, slender, of moderate length. Claws moderately arched, much compressed, acute.
Plumage soft and blended. Strong bristles along the basal margin of the upper mandible, and over the nostrils. Wings rather long, broad; the first five primaries much attenuated toward the end, the first more so, the fifth least; this attenuation being chiefly produced by an incision on the first web; the first four are nearly equal, the third longest, the fourth half a twelfth shorter, the third one-twelfth shorter than the hind, and exceeding the first by nearly two-twelfths; the other primaries gradually broader and more rounded; outer secondaries abrupt and slightly emarginate. Tail rather long, almost even, of twelve broad, abruptly rounded and acuminate feathers.
Bill black. Iris brown. Feet and claws black. The general colour of the upper parts is ash-grey, the back tinged with yellow; the wing-coverts and quills chocolate-brown, with brownish-white edges, those of the inner secondaries broader. Upper tail-coverts and tail black, excepting the outer web of the lateral feather on each side, and the basal margin of the next. There is a patch of bright vermilion on the top of the head, tinged with orange-yellow behind. Throat greyish-white, the sides and fore part of the neck pale ash-grey, shaded on the fore part of the breast into pure yellow, which is the prevalent colour of the lower parts; lower wing-coverts yellow, the middle ones tinged with grey.
Length to end of tail 9 inches, to end of wings 7, to end of claws 7, extent of wings 15 1/4; tail 3 7/8; wing from flexure 5 1/2; bill along the ridge 9/12, along the edge of lower mandible 1 1/12; tarsus 8 1/2/12; first toe 3 1/2/12, its claw 4 1/2/12; third toe 7/12, its claw 4/12.
Adult Female. Plate CCCLIX. Fig. 2.
The Female is rather smaller, but is similar to the male in colouring.
The young also is similar to the adult, but wants the red patch on the head.
In the female mentioned above as having been found in Texas, the mouth is half an inch wide, its roof anteriorly slightly concave, with three median prominent lines, the palate flat, with its membrane or skin diaphanous, as in Goatsuckers. The tongue is 7 twelfths long, deeply emarginate and papillate at the base; triangular, extremely depressed, tapering to a thin slit and bristly point. The posterior aperture of the nares is 4 twelfths long, linear, papillate on the edges, ending abruptly at its fore part, without a prolonged fissure. Œsophagus, a, a, b, 2 inches 9 twelfths long, funnel-shaped for half an inch, then cylindrical and nearly 4 twelfths in diameter, until it enters the thorax. Proventriculus, c, 3 1/2 twelfths in diameter, and with a belt of oblong glandules. Stomach c, d, elliptical, 7 1/2 twelfths long, 6 twelfths broad, its lateral muscles of moderate strength, the lower not distinct; the epithelium with broad longitudinal rugæ, and of a dark reddish-brown colour. Intestine, e, f, g, 7 inches long, its diameter at the anterior part 3 1/2 twelfths, gradually diminishing to 1 1/2 twelfth. Cœca extremely small, 1 twelfth long, 1/2 twelfth broad, and 1 1/4 inch distant from the anus; cloaca i, globular.
Trachea 1 inch 10 twelfths long, tapering from a diameter of 2 twelfths to 1 twelfth; the rings ossified and firm, about 70 in number; the lateral and sterno-tracheal muscles slender; the inferior laryngeal muscles are strong but very short, forming a prominent knob, and attached to the first bronchial ring. Bronchi wide, of about 20 half-rings.
The digestive organs of this bird, and of the Flycatchers in general, do not differ materially from those of the Thrushes and Warblers. The pharynx and œsophagus, however, are much wider.
