Quite a fine series of specimens from Jamaica and other West India Islands affords ample material to judge of the validity of the C. tixicrus of
Gosse. It is scarcely possible to distinguish these Jamaican specimens from examples from the Eastern Province of the United States, though minute differences are observable. Their size is somewhat smaller, but they are resident in the region where obtained; and the shades of color are just appreciably darker. There are, however, no differences sufficient to justify retaining the name tixicrus, to designate even a variety.
All the specimens in the collection from Mexico and Guatemala are in the autumnal or winter dress, so that it is probable that they are not resident there; they appear to be identical with North American specimens, and referrible to the variety passerinus as restricted.
Between summer and winter specimens great differences are observable; in the former season the edges of the feathers become worn, so that often the chestnut spots disappear entirely, while the other markings become poorly defined, leaving the black blotches predominant.
Habits. The common Yellow-winged Sparrow appears to be a bird of irregular and unequal distribution, found in certain localities in great abundance, and not seen in the intervening districts. According to some writers, it is partial to sandy places near the sea, and this is certainly true of the neighborhood of New York City, and also of a large portion of the New Jersey coast. It is likewise the case in certain portions of Eastern Massachusetts, as, according to Mr. Maynard, this species is very numerous in Nantucket, where it breeds abundantly. I have never met with this Sparrow in Massachusetts, except in a single instance, near Boston, nor in any collections of eggs have I seen any that I supposed could be those of this species; yet in the western part of the State, according to Mr. Allen, it is an abundant summer visitant, arriving there about the first week in May, and leaving early in September, breeding in dry fields and pastures, and raising two broods in a season. According to Mr. Boardman, it is an occasional visitant in the neighborhood of Calais, yet rare; arriving there the first of April, five weeks earlier than it shows itself in Springfield. Yet that this bird has ever been met with between Boston and Calais does not appear. It was not seen in Western Maine by Professor Verrill.
In the vicinity of Hartford, Conn., this bird appears also to be a not uncommon summer resident. In 1860, I received from Mr. T. S. Brandigee several nests found in that neighborhood. They were all constructed on the ground, in a field of thin grass, and their tops were all nearly covered over.
Dr. Heermann states that he found this bird a not uncommon species, in the summer season, near San Antonio; and Mr. Dresser also procured a specimen there in the early summer. Dr. Lincecum mentions it as a common resident in Washington County, in the same State. He describes it as a close-hiding Grass Sparrow, running on the ground in the manner of a mouse, and never seen to alight on trees. Dr. Coues speaks of it as a resident species in South Carolina, especially abundant during the period of migration.
It has been found quite common, during the winter months, in Central America, specimens having been procured there by Señor Constancia, Mr. Skinner, and Dr. Van Patten. It was also found at Oaxaca, Mexico, by Mr. Boucard.
Mr. Nuttall and Mr. Audubon speak of it as occurring in Oregon, but Dr. Cooper did not meet with it on the Pacific coast. Dr. Kennerly obtained a single specimen on one of the forks of the Colorado, in February. Mr. Ridgway met with the western form of this species, in suitable places, in the Sacramento Valley and the Great Basin, and proposes for it the name of perpallidus.
In the vicinity of Newark, N. J., I have found this species apparently one of the most abundant in that neighborhood, having obtained there in the month of June more eggs of this than of any other species.
