Is the Mountain Bluebird Resident at High Altitudes?
During the latter part of February and early March of this year (1907), Sialia arctica was very numerous in and about Flagstaff, Arizona, altitude 6800 feet; in fact, the commonest bird. That period also covers the coldest weather for that locality. And as this bird is a known breeder in northern Arizona (San Francisco Mountains), can we not infer that they are resident in that zone?
