obtained by Dr. Kennerly, naturalist to the Pacific Railroad Expedition on the 35th parallel, under Lieutenant Whipple. He met with it at Bill Williams Fork, in Arizona, February 5, 1854. It was described by Professor Baird the following June. Dr. Kennerly furnished at the time no information in regard to its habits.
Dr. Heermann, in his Report on the birds observed in Lieutenant Parke’s expedition, mentions having met with this species in the vicinity of Tucson. Its habits, so far as he could judge of them from his opportunities, appeared very similar to those of Pipilo aberti.
Lieutenant Couch met with this species at Santa Catalina, Mexico, in April, 1853, but furnishes no information in reference to its manners. Mr. J. H. Clark, who obtained a specimen near the Copper Mines of the Mimbres, states that they were met with in abundance in the deep valleys or cañons of that region. They were almost always in or about the thick clumps of bushes, several usually being in company.
Dr. Kennerly, who met with them on a second trip, in June, 1855, near Los Nogales, in Mexico, speaks of them as not very common in that region. He found them preferring the dense bushes in the valleys. When approached, they became very restless, flying from one bush to another, accompanying their motions with very peculiar notes, which he does not describe.
Dr. Coues found this species abundantly distributed throughout the warmer portions of New Mexico and Arizona, from the valley of the Rio Grande to that of the Colorado. He did not observe any at Fort Whipple, though they were found breeding some twenty-five miles to the southward. He found them associating freely with Pipilo aberti, and inhabiting the same regions. The two birds have very similar habits.
Dr. Henry also states that this species is common in New Mexico both summer and winter, and, so far as he has observed, dwelling almost entirely among the mountains. It appeared to him very retiring in its habits, and seemed to prefer the cañons. He has seldom, if ever, observed it far from shady gorges, where, like its relative of the Eastern States, the Towhee Bunting, it passes the greater part of its time on the ground, and is generally accompanied by its congener, the Arctic Finch. When disturbed, it seeks the thickest cover, though it is by no means shy or difficult to approach. Its nest is usually constructed in the branches of a thick cedar or dwarf oak, and he has never known it to produce more than one brood in a season.
Dr. Cooper states that these birds are very abundant in Southern Arizona, that their habits closely resemble those of P. aberti, and that their eggs are similar to those of Pipilo fuscus.
Pipilo albigula, Baird, P. A. N. S. Nov. 1859, 305 (Cape St. Lucas).—Elliot, Illust. Am. Birds, I, pl. xv (“= P. mesoleucus”).—Cooper, Orn. Cal. I, 248.
Sp. Char. Similar to var. mesoleucus, having, like it, a distinctly rufous crown and white abdomen. Differing, however, in the following respects: The pale ochraceous gular area is more sharply defined, the buff being confined within the encircling series of dusky spots; the buff is palest posteriorly, instead of directly the opposite. The rufous of the crissal region is more restricted, only tingeing the anal region instead of invading the lower part of the abdomen, the white beneath also is shifted farther back, covering the abdomen alone, instead of the breast, the whole jugulum being distinctly ashy, like the sides. Wing, 3.80; tail, 4.25.
Hab. Cape St. Lucas.
A very large series of specimens from Cape St. Lucas agree in possession of the characters pointed out above, distinguishing them from mesoleucus, to which race the present one is most nearly related.
Habits. The White-throated or Cape Towhee of Cape St. Lucas was first met with by Mr. Xantus in the southern extremity of the peninsula of Lower California, and described by Professor Baird in 1859. Its close resemblance to P. mesoleucus suggests an equal similarity as to its habits, in regard to which we possess no actual knowledge. Mr. Xantus has furnished us with no memoranda as to the manners of the bird. We have only the brief mention among his notes to the effect that No. 4,855 is the nest with four eggs of this Pipilo, found in a wild Humulus thicket; and that No. 5,076 is a nest with eggs of the same, found in a thicket of wild roses in the garden fence.
Judging from the large number of the nests and eggs of this species collected by that gentleman at Cape St. Lucas, it would seem to be very abundant in that locality.
The eggs of this variety measure .95 of an inch in length and .72 in breadth. They bear a strong resemblance to those of the P. fuscus, but the markings are darker and more distinctly defined, standing out with a clear and striking effect, in marked contrast with the light background. The ground-color of the egg is a light tint of robin-blue. The markings of dots, dashes, and lines are all about the larger end, and are of a deep dark shade of purplish-brown, so dark as, except in a strong light, to be undistinguishable from black.

6748 ♂
Sp. Char. General color of upper parts pale brownish yellowish-red; beneath brighter, and more ochraceous, especially on the under coverts, palest on the middle of the belly. Sides of head anterior to eyes, and chin dark brown. Bill and legs yellowish. Length, 9 inches; wing, 3.70; tail, 4.85.
Hab. Base of Rocky Mountains in New Mexico. Valley of Gila and Colorado.
This plainly colored bird is perhaps the largest of the North American Finches, and is without any blotches, spots, or variations of importance from one color, except on the chin and sides of the head. The bill is similar to that of P. erythrophthalmus, but the cutting edge is less concave and more sinuated. The tail is more graduated; the claws thicker and stronger. The wings are short and much rounded; the first quill shorter than the secondaries; fifth and fourth longest.
It may be easily distinguished from all the varieties of fuscus by the blackish lores and chin, as well as by the absence of any colored gular area, there being, instead, a pinkish rufous tinge prevalent over the whole throat and jugulum. There are no dusky spots across the throat as in fuscus.
Habits. Dr. Cooper assigns the base of the Rocky Mountains, in New Mexico, and the valleys of the Gila and Colorado Rivers, as the habitat of this species. Dr. Coues speaks of it as one of the most abundant and characteristic birds of those two valleys, and adds that it ranges northward to within a few miles of Fort Whipple, but is not found in the adjacent mountains. It was common at Fort Mohave, and particularly so at Fort Yuma.
Dr. Kennerly met with it at Camp No. 114, New Mexico, February 6, and again at Bill Williams Fork, February 12. He states that while travelling down the Big Sandy Creek and Bill Williams Fork, in the month of February, he found them very abundant. They confined themselves to the thick bushes near the water. Generally two or three were seen together. Their motions were very rapid, and their note was a peculiar, loud, chattering sound, sharp but not disagreeable. After leaving the Great Colorado he did not see it again.
On the borders of the Gila, east of Fort Yuma, Dr. Heermann found this bird in great abundance. It kept in the close sheltered thickets, where, secure from intrusion, it sought among the dead leaves for various seeds and insects and their larvæ, on which it feeds. In its habits it very much resembles the Pipilo fuscus, or Cañon Finch, diving into the bushes when alarmed, and repeating, at intervals, a short chirp. After leaving the Gila River he did not meet with any more, as he followed no longer the course of any large stream, for the borders of which these birds seem to have a decided preference.
Dr. Cooper regards this species as the almost exact counterpart of the Pipilo fuscus. The only difference he noticed in habits was in the character of its loud note of alarm, remarkably similar, however, to that of two very distinct birds of the same valley, namely, Centurus uropygialis
