Sp. Char. Tail strongly cuneate and wedge-shaped. Upper parts, lower tail-coverts, and breast cinnamon. A trace of metallic green on the crown, which sometimes extends over the back, never on the belly. Throat coppery red, with a well-developed ruff of the same; below this a white collar. Tail-feathers cinnamon, edged or streaked at the end with purplish-brown. Female with the rufous of the back covered or replaced with green; less cinnamon on the breast. Traces only of metallic feathers on the throat. Tail rufous, banded with black and tipped with white; middle feathers glossed with green at the end. Tail still cuneate. Length of male, 3.50; wing, 1.55; tail, 1.30.
Hab. West coast of North America, and across from Gulf of California to the Upper Rio Grande Valley, and along the table-lands of Mexico, south; in Middle Province east to East Humboldt Mountains.
Specimens from the table-lands of Mexico are smaller than those from Oregon, and have yellower, less ruby throats.
Selasphorus rufus.
Habits. This brilliant species has an extended distribution throughout the western part of North America, being found from the valley of the Rio Grande to the Pacific, and from Mexico to Sitka. It was first discovered near Nootka Sound, by that distinguished navigator, Captain Cook, and described by Latham, and has been met with as far to the south as Real del Monte, on the table-lands of Mexico, by Mr. Taylor, whose specimens were described by Mr. Swainson.
Dr. Coues found it very abundant at Arizona, near Fort Whipple, as it is also along the whole slope of the Rocky Mountains. It is a summer resident in that Territory, and breeds there abundantly, arriving at Fort Whipple April 10, and remaining until the middle of September, being found in all situations, particularly meadows, open copses, ravines, etc., where flowers are most abundant.
Mr. Dall gives them as common summer residents at Sitka. Bischoff obtained sixteen specimens. Dr. Suckley says they are very abundant in the western provinces of both Oregon and Washington Territory, and in Vancouver Island. They appear to be very hardy, and are one of the earliest of the migratory birds to arrive in spring. At Fort Steilacoom, latitude 47°, they appeared April 10. They are supposed to commence their southern migrations from that region in September,—a move induced by the scarcity of flowers and lack of means of captivating insects, rather than by cold. In Washington Territory their incubation commences about the 10th of May, and is made evident by the fierce and angry battles continually occurring between the male birds, in which they tilt at each other at full speed, at the same time keeping up a loud and vociferous squeaking and buzzing.
A nest with eggs, of this species, obtained by Dr. Cooper near Fort Slaughter, May 23, was found in the forked branch of a snowberry-bush. It was composed principally of fine green moss, lined internally with the delicate floss of the cottonwood, and externally bordered most artistically with rock lichens. The female was on the nest, and allowed so near an approach as almost to admit of being grasped by the hand. The nest was 2.00 inches in diameter and 1.50 in height. The eggs measured .45 by .33 of an inch, and were white, as in all the species.
Dr. Cooper states that the appearance of this species at the Straits of Fuca is coincident with the blossoming of the red-flowering currant, which begins to bloom on the Columbia March 10. The male of this species has a remarkable habit, when a stranger or a wild animal approaches its nest, of rising to a great height in the air, and of then darting down perpendicularly
