Sir John Richardson speaks of it as not uncommon in the Arctic regions. It is abundant in Canada, and throughout all parts of the United States. Dr. Gambel met with it also in large numbers in the wooded regions of Upper California. Dr. Heermann found it very common around Sacramento in 1849, but afterwards, owing to the increase in population, it had become comparatively rare. Dr. Woodhouse met with it in the Indian Territory, though not abundantly. Lieutenant Couch obtained specimens in Mexico, and Mr. Schott in Texas.
Bubo virginianus.
In the regions northwest of the Yukon River, Mr. Robert Kennicott found a pair of these birds breeding on the 10th of April. The female was procured, and proved to be of a dark plumage. The nest, formed of dry spruce branches retaining their leaves, was placed near the top of a large green spruce, in thick woods. It was large, measuring three or four feet across at base. The eggs were placed in a shallow depression, which was lined with a few feathers. Two more eggs were found in the ovary of the female,—one broken, the other not larger than a musket-ball. The eggs were frozen on their way to the fort. Mr. Ross states that he found this Owl very abundant around Great Slave Lake, but that it became less common as they proceeded farther north. It was remarkably plentiful in the marshes around Fort Resolution. Its food consisted of shrews and Arvicolæ, which are very abundant there. It is very tame and easily approached, and the Chipewyan Indians are said to eat with great relish the flesh, which is generally fat.
Mr. Gunn writes that this Owl is found over all the woody regions of the Hudson Bay Territory. In the summer it visits the shores of the bay, but retires to some distance inland on the approach of winter. It hunts in the dark, preying on rabbits, mice, muskrats, partridges, and any other fowls that it can find. With its bill it breaks the bones of hares into small pieces, which its stomach is able to digest. They pair in March, the only time at which they seem to enjoy each other’s society. The nest is usually made of twigs in the fork of some large poplar, where the female lays from three to six pale-white eggs. It is easily approached in clear sunny weather, but sees very well when the sky is clouded. It is not mentioned by Mr. MacFarlane as found near Anderson River. Mr. Dall caught alive several young birds not fully fledged, June 18, on the Yukon River, below the fort. He also met with it at Nulato, where it was not common, but was more plentiful farther up the river.
Mr. Salvin found this species in August at Duenas and at San Geronimo, in Guatemala. At Duenas it was said to be resident, and is so probably throughout the whole country. It was not uncommon, and its favorite locality was one of the hillsides near that village, well covered with low trees and shrubs, and with here and there a rocky precipice. They were frequently to be met with on afternoons, and at all hours of the night they made their proximity known by their deep cry.
Dr. Kennerly found it in Texas in the cañon of Devil River, and he adds that it seemed to live indifferently among the trees and the high and precipitous cliffs. It was found throughout Texas and New Mexico, wherever there are either large trees or deep cañons that afforded a hiding-place during the day. Attracted by the camp-fires of Dr. Kennerly’s party, this Owl would occasionally sweep around their heads for a while, and then disappear in the darkness, to resume its dismal notes. Sometimes, frightened by the reverberating report of a gun, they would creep among the rocks, attempting to conceal themselves, and be thus taken alive.
Though frequently kept in captivity, the Great Horned Owl, even when taken young, is fierce and untamable, resenting all attempts at familiarity. It has no affection for its mate, this being especially true of the female. Mr. Downes mentions an instance within his knowledge, in which a female of this species, in confinement, killed and ate the male. Excepting during the brief period of mating, they are never seen in pairs.
Its flight is rapid and graceful, and more like that of an eagle than one of this family. It sails easily and in large circles. It is nocturnal in its habits, and is very rarely seen abroad in the day, and then only in cloudy weather or late in the afternoon. When detected in its hiding-place by the Jay, Crow, or King-bird, and driven forth by their annoyances, it labors under great disadvantages, and flies at random in a hesitating flight, until twilight enables it to retaliate upon its tormentors. The hooting and nocturnal cries of the Great Horned Owl are a remarkable feature in its habits. These are chiefly during its breeding-season, especially the peculiar loud and vociferous cries known as its hooting. At times it will utter a single shriek, sounding like the yell of some unearthly being, while again it barks incessantly like a dog, and the resemblance is so natural as to provoke a rejoinder from its canine prototype. Occasionally it utters sounds resembling the half-choking cries of a person nearly strangled, and, attracted by the watchfire of a camp, fly over it, shrieking a cry resembling waugh-hōō. It is not surprising that with all these combinations and variations of unearthly cries these birds should have been held in awe by the aborigines, their cries being sufficiently fearful to startle even the least timid.
