Avian pox in California quail from Oregon.

California quail (Lophortyx californicus) from several locations in Oregon were examined seasonally between fall 1975 and summer 1978 for avian pox. Pox lesions were present on 66 of 256 (26%) birds from the E.E. Wilson Wildlife Area. None of the remaining 41 birds from other areas was infected. Rates of infection of males and females were equal; juveniles had a slightly, but not significantly, higher prevalence of pox than did adults.
