The present species, given the English name of mountain partridge, by the ornithologists, and which he has taken for his type, is a small race found only on the Coast Range from the Bay of San Francisco north into Oregon, and, therefore, never reaches the high altitudes reached by its near relatives, the Oreortyx pictus plumiferus, to which the English name, plumed partridge, has been given. In fact, both of these varieties are plumed, though that of the latter is a trifle the longer. The fact that the plumed quail ascends the mountains each spring to heights of from five to eight thousand feet for nesting purposes, gives it a better claim to the name, mountain, than has the other variety.
The present species, the mountain quail, is generally found in the canyons and on the damp hill-sides where ferns are abundant. They have very little of the migratory habits of the other species, except when driven down in the winter by the snows. Their habits and general plan of coloration are so much like those of the other two species that I shall describe them all together, with the proper mention of wherein they differ.
THE PLUMED QUAIL
(Oreortyx pictus plumiferus)
The range of the plumed partridge is throughout the entire length of the Sierra Nevadas and of the coast range south of San Francisco bay into Lower California, where it intergrades with the San Pedro partridge, but it does not cross the Colorado river and enter Arizona or the mainland of Mexico. This species begins its migrations early in the spring, keeping close to the snow line until they reach altitudes as high as 7000 to 8000 feet, where they nest and rear their young. In the fall, just before the winter rains begin, they commence their migrations down again to the foothills, where they remain until the following spring. Unless driven by unusually heavy snows, they rarely descend lower than 2000 to 3000 feet above sea level.
SAN PEDRO MARTIR MOUNTAIN QUAIL
(Oreortyx pictus confinis)
The San Pedro partridge, so named by the ornithologist, is a resident of the San Pedro Martir mountains of Lower California, and ascends to a height of ten thousand feet, and is rarely seen lower than five thousand feet above the sea.
I want to say here that no work on ornithology that I have seen, describes the San Pedro partridge properly. Most likely this is the result of an examination of the intergrades only, for they do intergrade with the California species to the northward. The two species first mentioned have the plume from one and a half to two and a half inches long and nearly round in form. The plume of the San Pedro partridge is flat, about three-sixteenths of an inch wide and from three and a half to four and a half inches long. The plume of the other varieties is erectile, but that of the San Pedro denizen is soft and falls down the side. In all species both sexes are alike, with the exception that the plume of the female is generally a trifle the shorter; but this can not always be relied upon to distinguish the sex.
Generally speaking there is not much sport in hunting the mountain quail, but I have at times had a bevy scattered in ferns, and in such cases had very good sport with them with a dog, and found them to lie very well. They are about a half larger than the valley quail, and as a table bird much more succulent.
