Mr. B. R. Ross speaks of Ravens as common as far north as the Arctic Ocean. They feed on carrion, and act as scavengers to the establishments. Their sight is remarkably keen, and the sagacity with which they follow the trapper is wonderful. Early as the hunter may start, these harpies will have been before him, and torn out the eyes and entrails of each hare. They will break into marten-traps for the sake of the bait or the captured animal, thrusting aside or pulling out with their beaks the sticks that compose the enclosure. Sometimes they are caught in steel traps that are set for foxes, or eat the strychnine baits laid for the same animals, and slowly succumb to this powerful poison. Their flesh is so rank that even a fox, unless sorely pressed by hunger, will not eat it. They pair in April, and usually construct their nests in the loftiest trees. They have various call-notes, one of which is like that of the Canada Goose, and another is said by Mr. Ross to be very liquid and musical. Mr. Dall states that these birds were abundant all the year at Nulato, and indeed everywhere throughout Alaska, but much more common near the Indian villages and trading-posts than elsewhere. They build on the sandstone cliffs at Nulato, in cavities that have been occupied for years. They lay about the 20th of April, and the young are hatched before open water. He also speaks of them as very intelligent, and states that on several expeditions made to obtain their eggs, the instant he stopped at the foot of the bluff the whole colony would arrange themselves on the edge of the rock in anxious consultation, uttering repeated cries of warning. On one occasion, where the nest was inaccessible and the party went back unsuccessful, their departure was announced by significant and joyous croaks and derisive screeches. Ravens were also found by Mr. Bannister common all the year on the small islands lying off the northeast point of St. Michaels. In the Eastern States the Raven is a comparatively rare bird, except in a few special localities. These are usually mountain-ranges, high precipitous banks of rivers and lakes and of the ocean, and among wild and lonely islands. It occurs on the Labrador coast, at Grand Menan in the Bay of Fundy, the Adirondacks, Lake George, the Hudson River, etc. Mr. Lawrence speaks of it as quite common on the coast of New Jersey. It is found among the mountains of Buncombe and other counties in North Carolina, and Mr. Audubon mentions its occurrence at Table Mountain, in the district of Pendleton, South Carolina. Dr. Coues found Ravens not rare at Labrador, where the almost inaccessible cliffs afford them safe and convenient retreats. They were so excessively wary that it was found impossible to shoot them. They descended in pairs to the sea-shore to feed on dead fish, crabs, and other animal substances thrown up by the sea.
