“The Raven is not, on the whole, so noisy a bird as the Crow, though he croaks vigorously on occasion, and his caw may claim to be impressive, if not agreeable. But the queer sounds that the bird can utter, if he be so minded, are indescribable; even his ordinary cawing is susceptible of considerable modulation. A favorite amusement of his, when, his hunger appeased for the time, he feels particularly comfortable, is to settle snugly on the top of a pine-tree, and talk to himself. The performance generally begins with a loud caw, self-asserting, followed by a complacent chuckle; and then comes a series of comical syllables, so low as to be scarcely audible from the ground below, as if he were musing aloud, and tickled with his own fancies. Then he will raise his voice again, and file away at some old saw for a while, finishing with the inimitable ‘cork-drawing’ for which his tribe is famous. “A Raven that I had slightly wounded in the wing and captured soon became quite tame, and developed a variety of amusing traits. Proving rather obtrusive and inconvenient in my narrow quarters, I undertook to tie him in a corner with a string round his leg. This he objected to, and it was astonishing to see the perseverance he showed in untying any number of knots I might make. It was a task that sometimes took him hours, but he never rested until it was done. I had no chain light enough for the purpose, but I finally got the better of him by twisting a wire with the cord. His intelligence did not reach in that direction more than six inches from his leg.” Mr. Dresser observed the Raven common at San Antonio, frequenting the slaughter-houses. In November, in the Baudera Hills, several came to his camp to feast on the offal of deer. Dr. Woodhouse also found them very abundant in Texas, the Indian Territory, and New Mexico, and especially so on the buffalo plains. In the Mexican Boundary Survey, Dr. Kennerly observed these birds everywhere in Northern Mexico, flocks of them following the train from point to point. They were not at all shy, but often came into camp in search of food.
