The principal habitat requirement of the coyote seems to be extensive areas of open country. This it finds in the desert area of the Columbian Plateau, the open forests of northeastern Washington and the eastern Cascades, and in the extensive timbered and burned-over lands in western Washington. In summer coyotes range well up into the Hudsonian Life-zone of the Cascade and Olympic mountains. Their principal range is lower, in the Transition and Upper Sonoran life-zones. The coyotes are both nocturnal and diurnal. In the vicinity of human habitations they are most active at night. In the heat of the day they take refuge in brushy areas or small gullies. Many actions of the coyote are doglike, and were it not for the large, round, bushy tail, a coyote might easily be mistaken for a dog. The tail is carried in a drooped position with the tip bowed slightly backwards. When badly frightened and running at full speed the tail is stretched out straight behind. The ordinary gait is a purposeful trot with the head held erect, the ears pricked up, and the legs moving smoothly and effortlessly. Near Moses Lake, Grant County, I watched a coyote trot along the side of one of a series of small sand dunes. At the report of the small shotgun fired at it, the coyote's dignified trot changed to terrified bounds, its feet dug into the dune, throwing showers of sand into the air, as it crossed several successive dunes in full flight before turning to take advantage of the shelter of a draw between two dunes. A coyote chased by an automobile attained a speed of 43 miles an hour for a short distance (Zimmerman, 1943: 400). I have not watched a coyote stalk game, but as described to me it creeps up to within a few yards of its prey and catches it with a sudden dash. In hunting a jack rabbit, the coyote is said to pursue it, taking advantage of short cuts, until close enough to seize it. Better known than the coyote itself is its howl--several doglike barks, each successive one of a series shorter and higher pitched, the last one ending in a long, drawn-out howl. In the winter of 1936 the coyotes near Cottage Lake, King County, were especially vociferous. They ordinarily began to howl about 9 p.m., but could be induced to howl earlier by imitating their call. Their howling was a signal for all nearby ranchers' dogs to howl in reply. In the desert areas of eastern Washington I heard coyotes most often just at dusk or at dawn. The coyote is principally carnivorous, feeding on any mammals and birds easy to kill. It willingly eats carrion, even when much decayed. Large insects such as grasshoppers and crickets are eaten when they are abundant and easily caught. Fruit and berries are eaten when available.
