Columba fasciata.
Specimens—even those from the same locality—vary a great deal in size, particularly as to the bill, and there is also considerable variation in the shade and depth as well as the extent of the purplish tint; this varies from a purplish-chocolate tint to nearly violaceous, and sometimes tinges the ends of the lower tail-coverts; sometimes the back has faint bronzy reflections. Guatemalan skins have the white edgings to the wing-coverts less conspicuous than in northern ones, showing an approximation to the features of var. albilinea of Costa Rica; they also have a shorter bill than California specimens. Oregon birds, on the other hand, have longer bills than the California, and are considerably darker in color.
Habits. The Band-tailed Pigeon was first met with in Long’s expedition to the Rocky Mountains, and described by Say in 1823. It is found from the northern Rocky Mountains westward to the Pacific, and from Central America northward along the whole of the Pacific Coast as far to the north as Washington Territory, and probably portions of British Columbia.
Mr. Townsend, quoted by Audubon, noticed this Pigeon from the eastern spurs of the Rocky Mountains across to the Columbia River, where it was very abundant. He noticed their arrival in very great numbers on the 17th of April, and they continued in large flocks even while breeding. Their breeding-places were on the banks of the river, the eggs were placed on the ground, under small bushes without any nest, where numbers congregated together. The eggs were two in number, and are described as of a yellowish-white color, some inclining to a bluish-white with minute white dots at the larger end.
These birds feed on the berries of the black-elder and the buds of the balsam poplar. When sitting on the trees, they huddle close together in the manner of the Carolina Parrot, and many may be killed at a single discharge. Their flesh is said to be tender, juicy, and fine eating.
Mr. Nuttall states that this Pigeon is always in flocks, and in Oregon keeps only in the thick forests of the Columbia and the Wahlamet, and during the summer is more particularly abundant in the alluvial groves of the latter river, where he constantly heard its cooing, and saw it in large flocks, feeding on the berries of the elder, the Cornus nuttalli, and the seed-germs and young pods of the balsam poplar. Its call is somewhat similar to that of the Carolina Dove, but is readily distinguishable, is uttered at the usual intervals, and is repeated an hour or two at a time, chiefly in the morning and evening. It remains on the lower part of the Columbia nearly the whole year, feeding on the berries of the tree cornel, moving south only in the severity of winter.
Mr. Salvin found this Pigeon at Volcan de Fuego, in Guatemala, at an elevation of six thousand feet, and at Coban. It was quite common in the high forests of the Volcano.
Dr. Woodhouse met with small flocks of these Pigeons in different parts of New Mexico, and especially in the San Francisco Mountains, now included within the limits of Arizona.
