HABITS. Notwithstanding the apparent abundance of the species at Cape St. Lucas, and also in Northern Mexico along our entire border, as far as New Mexico and Texas, our knowledge of its history still remains quite incomplete. A single specimen was obtained in Western Texas on the Pecos River, by Captain Pope, in 1856. Others were obtained by Lieutenant Couch, April, 1853, at Santa Catarina, in Mexico. They were first seen by him in the vicinity of Monterey. They were found to be generally of secluded habits. Their song, consisting of three or four notes, is said to be both rich and melodious. In the State of Vera Cruz, this species is given by Sumichrast as occurring in both the temperate and the alpine regions. Its common name is _Calandria india_. They are said by him to occur chiefly in the temperate parts, where they breed, but not to be exclusively confined there, for they are also found in the alpine region to the height of at least five thousand feet, near Orizaba, and on the plateau at even a higher elevation. Dr. Cooper saw a bird at Fort Mohave, in April, which he supposed to be this bird, but he was not able to assure himself of the fact, by obtaining it. Mr. Xantus found this species very abundant during his stay at Cape St. Lucas, and procured a number of specimens of the birds and of their nests and eggs. From his brief notes we gather that the nests are open, and are not pensile. One, found May 22, was built in a bunch of moss hanging down from an old cactus. Another was made in a bunch of hops, suspended from a cactus. A third was placed in a bunch of weeds growing out from a crevice in a perpendicular rock. Another, found May 29, was built in a small dead tree, overhung with vines. This nest was about five feet from the ground. A nest containing four young birds was found placed in a bunch of moss, hanging out of a crevice in a rock. These instances serve to show the general character of the position of their nests. Without being pensile they are usually resting upon pendent branches, and are not placed at great elevations. The eggs measure .90 of an inch in length by .65 in breadth. Their shape is an oblong-oval, and they are obtuse at either end. Their ground-color is a dull white, with a purplish or a bluish tint. They are variously marked, in different eggs, with small blotches and finer dottings of a light purple, purplish-brown, darker purple, and even black. [42] _Icterus wagleri_, SCLATER, Pr. Zoöl.
