I live on a ranch, and we are somewhat troubled by field mice and mountain rats, and so we must keep cats. We have them, but we do not keep them long, because they are caught by coyotes. Within a few months I have lost four cats in this way. The coyote has been known to kill the young of most farm animals--colts, calves, pigs, lambs, and goats. Colts are seldom killed, because the dam can usually protect them. Calves are taken only when the mother cow is feeding at a distance or has gone for water. The coyotes lie watching in the grass until this opportunity comes. Sometimes older animals are killed. Ranchmen in Oklahoma told the writer that in winter yearling cattle in good condition are sometimes killed by coyotes. To accomplish this two or more of them must hunt together, and get the victim separated from the herd. Capt. P. M. Thorne, writing to the Biological Survey from Fort Lyon, Colo.. January 4, 1887, says: Old cattlemen who have lived here nearly all their lives agree in saying that the coyotes kill cattle, even full-grown ones. They say that they have seen them at their work, which is done in packs; they surround an animal and keep up a constant nipping at its legs until it falls from weakness and loss of blood. In July. 1893, at Farmington, Utah, Vernon Bailey saw two coyotes chasing calves and yearlings about a pasture, evidently trying to separate one from the lot. He notes that in June. 1889, at St. Thomas, Nev., coyotes killed a hog that weighed about 100 pounds. THE COYOTE'S RELATION TO THE SHEEP INDUSTRY. The coyote is especially notorious as an enemy of the sheep industry. In many parts of the West sheep raising has greatly languished because of the depredations of wild animals upon the flocks. While some of the injury is caused by the larger wolves, mountain lions, bears, and lynxes, the coyotes are by far the most formidable enemy. They are not only more abundant than the other animals mentioned, but they are present throughout the year, and their depredations are a steady drain upon the resources of the flock owner, comparable in extent to the losses caused by worthless dogs in many parts of the country.[D] [Footnote D: In 1801 the loss from dogs was placed at $152,034 in Ohio and $200,000 in Missouri. (Sheep Industry in the United States. U. S. Dept of Agric, 1892.)] Dr. E. A. C. Foster, writing from Russell, Kans., in 1887, said: Of mammals, the prairie wolf is perhaps the most troublesome. It is constantly preying upon sheep and lambs; so much so that sheep can not be left alone without some of them falling a prey to this animal. Should the herder be absent or out of view, the wolf makes a dash into the flock and usually secures a lamb. William Lloyd, writing from Paint Rock, Concho County, Tex., said: In January. 1886, coyotes killed over 30 sheep near Fort Stockton, and in March about 20 at Toyah, Tex.
