In California and in all the adjacent regions, Dr. Cooper states, the Raven is found everywhere in pairs, more numerous than in the Atlantic States, and abundant even in the most barren desert districts. It follows trains and herds of cattle, and keeps on the lookout for anything befalling them. It is omnivorous, eating snakes, lizards, eggs, carrion, and even grain, though the last very rarely. It is accused of destroying young chickens and lambs. In Arizona Dr. Coues speaks of it as resident, and very abundant about the cattle enclosures, where it congregates in immense numbers during the autumn and winter. During the severe winter of 1864-65 great numbers perished of cold and hunger at Fort Whipple. Dr. Coues has favored us with the following interesting sketch of the habits of this bird as observed by him in that Territory. “The geographical distribution of the Raven seems to be in great measure complementary to that of the Crow. On the prairies, in the desert, among the mountains, of the Western States and Territories, where the Ravens and their congenial companions, the coyotes, abound, the Crows are rare or wanting altogether. In travelling westward, I saw no Crows after leaving the settlements this side of the Plains, while the Ravens were conspicuous, until in some parts of Southern California Crows reappeared, but no Ravens amongst them. I saw a fair number of Ravens along the Arkansas River, and they were frequent in the valley of the Rio Grande; after crossing the river, while traversing the wild region thence to the Colorado, they were our inseparable companions; hundreds, if not thousands, of them lived about Fort Whipple all the year, seemingly attracted from miles around by probabilities of finding abundant food. Throughout the Western wilds they hang on the footsteps of man, needy adventurers, claiming their share of his spoils, disputing with the wolves and vultures for the refuse of his camp, and polishing the skeletons of the buffalo, with which he sometimes strews the plain. The more desolate the land, the closer the Raven follows in the trail of the emigrant, till its dismal croaking sounds ominous of hardship, and its plumage seems to foreshadow days as dark.
