He first met with this bird on the spur of the Sierra Nevada, near Lassen’s Butte, and found it constantly, when in high and timbered regions, from there to the Columbia. He describes its habits as a compound, in about equal parts of those of the Jays and of the Woodpeckers. Its cry he speaks of as particularly harsh and disagreeable, something like that of Steller’s Jay, but louder and more discordant. It seems to combine the shrewdness with all the curiosity of the Jays and Crows, and from its shyness is a very difficult bird to shoot, the Doctor never being able to get directly within killing distance of one of them, but only obtaining specimens by concealing himself and waiting for them to approach him. Apparently from excess of caution, it almost invariably alights on a dry tree. Even when going to a living tree for its food, it always flies first into a dry one, if one is near, to reconnoitre, and, if the coast is clear, it begins to feed. At the first movement of an intruder, without uttering a note, it puts a safe distance between itself and its enemy.
The food of this bird, at the time when Dr. Newberry visited its haunts, consisted exclusively of the seeds of the yellow pine (P. ponderosa), in dislodging which from the cones the bird displays great dexterity. Both Maximilian’s Jay and Steller’s Jay were, at that time, feeding on the same seeds, but not so exclusively.
Dr. Suckley obtained a specimen of this bird as far east as Milk River, in Nebraska, about two hundred miles east of the Rocky Mountains.
In crossing the Cascade Mountains, in 1853, Dr. Cooper found these birds quite abundant on the banks of the Yakima River, and from thence north wherever there were trees of the long-leaved pine, the seeds of which were its principal food. On returning to Vancouver during the severe cold weather of the following January, these birds appeared there in considerable numbers. At no other season of the year has he met with them west of the Cascade Mountains, and believes these migrations westward are only made in the severest weather. They extend eastward throughout Washington Territory, as Dr. Cooper has shot them at Fort Laramie, and met with a straggling pair even as far east as Fort Kearney. Dr. Cooper has never known these birds to eat anything except seeds and berries. They rarely descend to the ground, and never frequent river-banks, or other places, for fish or carrion. They may be seen on the tops of trees extracting seeds from cones, hanging head downwards, like a Chickadee. Dr. Cooper has observed this bird pecking at dead bark, in quest of insects. When feeding they are very shy, flying off, if approached, to a great distance before alighting. They are not known to visit the Coast Mountains south of San Francisco, but abound in the Rocky Mountains throughout our limits.
Mr. J. K. Lord notes the arrival of this species at Fort Colville, in May, in large flocks. They were hopping busily from branch to branch, amidst pine-trees.
The statement made to Wilson that this species frequents rivers and seashores, and his inference that its formidable claws indicated that they feed on living animals, is controverted by Mr. Lord. They never frequent river-banks, never by any chance eat fish, and never capture any living thing. Their habits are strictly arboreal, and their food the seeds of pine-trees. These noisy seed-hunters use their formidable claws to enable them to hang on to the pine cones while they are extracting the seed, which they are obliged to get out from under scaly coverings. For this nature has given them feet and claws that serve the purpose of hands, and a powerful bill, like a small crowbar. The cone must be steadied when they pry it open, or it would snap and fall. One foot clasps it, and the powerful claws hold it firmly. The other foot, encircling a branch, supports the bird in every possible position, the long grasping claws being equal to any emergency. The cone is thus fixed, and the seeds are forced out from under the scales. Mr. Lord collected a large packet of seeds of the Abies douglassi from the crops of these birds.
On their arrival they assemble in immense flocks, and the noise they make he describes as a most discordant, continuous, grating clatter, intensified at times into a perfect shriek. These assemblies last about a week, after which they separate in pairs.
A nest of this bird was found by Mr. Lord in the top of a lofty pine at least two hundred feet high,—felled in cutting the boundary line. By chance he discovered the nest, about which the old birds were hovering, leaving no doubt of its identity. This nest was very large and composed of fir twigs, bits of bark, the leaves of the pine, fine root-fibres, with small pieces of moss, and gray lichens mixed carelessly with the other materials. It was shallow and round, and presented a large extent of surface beyond the margins of the hollow containing the eggs. The eggs were in fragments, much like the eggs of Steller’s Jay in color, but of a lighter shade of bluish-green. He thinks that their habit is to build in the very tallest pines.
Dr. Kennerly also met with this Crow west of Albuquerque, in New Mexico, in the thick pine woods skirting the eastern slope of the Rocky Mountains, where it was quite abundant. He rarely saw more than two or three together. None were met with after leaving the mountains.
A single specimen of this crow was obtained at Sitka, by Bischoff.
