One of the foremost birds in the spring movement is the grass-finch (vesper-sparrow or bay-winged bunting). It is to be found in open fields and along roadside fences, in company with meadow larks, and its sweet song may be heard almost any warm evening after the middle of April. Unlike most of our birds, this sparrow sings at its best late in the afternoon and during twilight, which perhaps makes its song seem the sweeter. It is rather a gentle song, though to be heard at some distance, carrying quite as far as that of the song-sparrow. Although the quality of voice is somewhat similar in these two birds, the grass-finch lacks the merry abandon that characterizes the song-sparrow's song, but has instead a deeper chord, which is called by some people sadness. The bird may be easily recognized in the fields by the white tail-feathers, which always show in flight. It is about the size and general color of the song-sparrow. * * * * * By the time the foregoing birds are comparatively common, and the maple buds are bursting and the lilacs swelling, the gay purple finch appears. He is not purple at all, but has a crimson head, which fades on the lower breast through rosy pink into pure white. He is fond of spruces and larches, feeding greedily on the tender buds as well as on the ants and scale insects that infest them. His song is a fine one, and in addition to the charm of being poured forth in full flight, is so long and intricate that one finds himself holding his breath as the burst of melody continues, as if to help the little fellow catch up with his music. * * * * * Along the banks of some lake or stream, sitting idly on a telegraph pole or wire, rising and settling, elevating and depressing his long parted top-knot, a patriarchal old kingfisher may be seen silently awaiting the gleam of a shiner in the water below (Fig. 182). Or perhaps you may first see him flying like a big woodpecker, screaming his chattering cry high in the air, or scaling close to the water under the fringing hemlock branches that overhang the stream. His large size, slate-blue back, loud notes, and characteristic flight make him a hard bird to mistake in any case. [Illustration: _Fig. 182. Kingfisher._] * * * * * There are many other birds which pass us on their way north, but they herald rather the summer than the breaking of spring. The following list of spring migrations is taken from Mr. Chapman's "Handbook of the Birds of Eastern North America," and was compiled for use about New York City. The dates nearly coincide with those I have found about the central part of the State, and are, in the main, only a few days in advance of those for the northern counties. The latter dates in the column are about what may be taken for the middle tier of counties.
