Patelka 1947 Oct. 15 6½ mi ESE Tule Pk, 4500 ft., Virginia Mts, Washoe Co., Nev. Apus striatus, Carpodacus mexicanus, Setta [illegible] Orychthus vociferus, and Junco oreganus The weather was unfavorable for effective hunting, quite apart of the facts of time of day and time of year, so that relatively few birds were noted. The riparian vegetation together with adjoining woodland would seem to provide suitable habitat for scrub jays unless the excessive grazing may now operate to change it effectively. Other pos- sible explanations for their absence are excessive local shooting, as evidenced by abundance of various sized empty shells on the ranch grounds; local absence of pinyons, that is, a woodland without pinyons may be a marginal habitat not necessarily all occupied; local post-breeding and late summer-early fall movements from areas which become very warm then (I doubt breeding pairs would leave the area). The fact remains that scrub jays have been collected in this area, probably on the very grounds of the TH Ranch, and I do not see why they should be absent.
