Captain Blakiston met with this species on the plains of the Saskatchewan, near the Rocky Mountains, August 6, 1858.
In the eastern portion of Massachusetts it is somewhat irregular in its movements and appearance, which are supposed to be affected by the abundance or scarcity of its food elsewhere. Here it feeds chiefly on seeds of grasses and weeds, probably only after the seeds of the hemlock and other forest trees have failed it. They are usually most abundant late in the season and after heavy falls of snow farther north have diminished their means of subsistence. Mr. Maynard found it very numerous in the winter of 1859-60, remaining until quite late in the season, and again in the winter of 1868-69, remaining until the last week in May. In Western Massachusetts, according to Mr. Allen, it is a regular winter visitant, but never abundant. It arrives early in October, and may be seen in small flocks from that time to the third week in May. It sometimes frequents the apple-orchards, where it feeds on the Aphides. According to Dr. Coues, this species occasionally strays as far to the south as the Carolinas, but it is not common there.
Wilson observed these birds near Philadelphia, where they were feeding on the seeds of the alder. Later in the season they collected in larger flocks and took up their abode among the pine woods. In one particular locality, he states, a flock of two or three hundred of these birds regularly wintered, for many years in succession, where noble avenues of pines furnished them with abundant food throughout the season. Early in March they all disappeared. While there, they were so tame as to allow a person to approach within a few yards. They fluttered among the branches, frequently hanging from the cones, at the same time uttering notes closely resembling those of the Goldfinch.
In severe winters Mr. Audubon has met with the Pine Finch as far south as Henderson, Ky., and Charleston, S. C., but such visits were always brief. In August, 1832, he met with flocks of these birds in Labrador. They were in company with the Crossbill, and were feeding on the seeds of the fir-trees, and also on those of the thistle. When at the Magdalen Islands he frequently saw flocks moving from various directions. At Bras d’Or, towards the end of July, they were in great numbers, and the old birds were accompanied by their young. They frequented thickets of willows and elders in the vicinity of water, and were very fearless and gentle. According to his account they sing while on the wing, and their notes are sweet, varied, clear, and mellow, and, while somewhat resembling the song of the C. tristis, are perfectly distinct from it. Its flight is exactly similar, both gliding through the air in graceful and deep curves.
In Washington Territory Dr. Cooper found this Finch an abundant and constant resident, migrating to the coast in winter, where it feeds on the seeds of the alder. In summer they were gregarious, even when occupied with their nests and young. He has never met with any in California, not even in the Sierra Nevada, though they have been found by others along its whole western slope, as far south as Fort Tejon. They feed on the seeds of both coniferous and deciduous trees.
Early in May, 1859, a pair of these birds built their nest in the garden of Professor Benjamin Peirce, in Cambridge, Mass., near the colleges. It was found on the 9th by Mr. Frederick Ware, and already contained its full complement of four eggs, partly incubated. This nest was three inches in height and four in diameter. The depth of the cavity, as well as its diameter at the rim, was two inches. The base of this nest was a mass of loose materials, and the lower portions of the sides were hardly different. The upper and the inner portions of this fabric were much more compactly and neatly woven, or rather felted together. The outer layers consisted of small twigs of the Thuja, dried stems and ends of pine twigs, grasses, sedges, stalks of small vegetables, fine roots, bits of wool, and coarse hair. The whole was very closely lined with fine dry roots of herbaceous plants and the hair of small quadrupeds.
The eggs are of an oblong-oval shape, of a light green ground-color, spotted, chiefly at the larger end, with markings of a light rusty-brown. They measure .71 by .50 of an inch. They have a marked resemblance to the eggs of the Linariæ, but the ground-color is of a slightly lighter shade.
A nest of this species, found May 15, 1868, at Brunich, Canada, was composed almost entirely of pine twigs interlaced in a very neat and artistic manner. Its diameter was three and a half inches, and its height two inches. It was lined with hair. The cavity was one and a half inches deep and two inches wide.
