In autumnal and winter specimens the buff tints are much deeper than in

spring; the sides of the crown, as well as the dark markings on the back, more intensified, and in greater contrast with the lighter ashy and olive tints.

Habits. The Sharp-tailed Finch is one of the most striking and well-characterized of land-birds, and as peculiar to the sea-shore as the Tringæ. In habits it very closely resembles the whole family of Waders in many striking respects. Like them it feeds upon small crustaceans and minute marine insects, keeping about the water’s edge, walking upon the floating weeds and other substances raised by the tide, preferring this mode of life to a more inland residence, and only resorting to the uplands to feed upon the seeds of grasses and sedges when their food fails them at the water’s edge.

Dr. Coues is of the opinion that this bird does not breed in the neighborhood of Beaufort, N. C., and that it leaves for the North in May, having a more northern habitat than A. maritima. He does not coincide with those who detect a resemblance between the actions of the Ammodrami and of the Sandpipers. He thinks the manner in which they climb the reeds, slide up and down, and hang from them in various attitudes, is more like that of Nuthatches and Titmice. On the ground they seem to him unmistakably sparrow-like.

This Sharp-tailed Finch is abundant along the coasts of Connecticut and Rhode Island, and is also found in Massachusetts, though sparingly, and only in a few congenial localities. In the marshes of Charles River, near Boston, this species is occasionally common in the breeding-season. In the summer of 1869, Mr. H. W. Henshaw found quite a number of their nests. Mr. Maynard has also taken it among the marshes of Ipswich, which is probably about its extreme northern limit. It has not, so far as I am aware, been traced to Maine. In these localities it probably raises two broods in a season, as it appears there in May, and remains until into October. They are eminently terrestrial, run on the ground like mice, are difficult to flush, and can only be shot while on the wing. They lie close to the ground, and conceal themselves in the grass.

They are also very numerous in the marshes in the neighborhood of New York, and especially so in New Jersey, breeding along that coast to Cape May. How much farther south than this they are found I cannot state, but I did not meet with any at Cape Charles, where the maritimus was very abundant.

In the winter this species is found in large flocks along the shores of South Carolina and Georgia. Mr. Audubon, however, did not find any in Florida. In the marshes near Charleston they are found in immense flocks, so much so that Audubon has known of forty being killed at a single shot. They search in the sedgy marshes for their food when the tide is out, and, on the approach of the returning waters, retreat to the higher shores and to the rice embankments.

The flight of this species is quite different from that of any other bird, and by it they may at once be recognized. In flying, they also drop their tails very low.

Mr. Audubon states that during the winter the Sharp-tailed Finch is furnished with an extra quantity of feathers on the rump, for which he finds it difficult to account.

These birds are essentially maritime, are found only in the vicinity of the sea, and always keep immediately about the water, except when the inclemency of the weather drives them to the high grass of the uplands for shelter. They walk and run, or remain feeding on the floating weeds and other substances raised by the tide, with all the ease and fearlessness with which they move on the land. They are gregarious in the winter, and in the Southern marshes are found feeding in companies. During the breeding-season they keep more in pairs, and are found more isolated. At this time they are also shy, and difficult to detect. Their usual call-note is only a single tweet, and in the love-season their series of twitters Mr. Audubon thinks hardly worthy to be called a song. They feed indiscriminately on seeds, insects, small crustaceans, and various forms of refuse matter floated or thrown up by the tides.
