摘要
Three of the 4 forms of albinism that occur in avifauna have been detected in Zenaida macroura (Mourning Dove). Albinism is rare in this species, and the incidence rate of each age and sex cohort is not well known. Consequently, we examined the pigmentation of Mourning Doves encountered in the Coastal Plain of South Carolina, and classified the age and sex of all individuals. One adult male Mourning Dove had unusually light coloration of some feathers and the upper mandible. This pigmentation is consistent with partial albinism. This was the only individual out of 10,749 examined that appeared to be albinistic. This low incidence rate of albinism supports the conclusion that this condition is relatively rare in Mourning Doves (Mirarchi 1993).
