Each of 2,356 dove hunters ws sent 10 wing envelopes with instructions for recording data and handling wings. A total of 992 hunters submitted 22,362 wings in 2,349 envelopes that included mourning dove (Zenaidura maroura) and white-winged doves (Zenaida asiatica). The survey yielded information on (1) age ratios of the Arizona dove harvest ; (2) the chronologic and geographic distribution of the kill within the State ; and (3) the feasibility of using a wing survey to obtain reliable age ratios and kill data. The weighted kill for Arizona was 676,974 mourning doves and 182,711 white-winged doves. The young:adult age ratio in the kill of mouning doves was 0.83:1, which was abnormally low. Correction for differential vulnerability by use of banding data raised the ratio to 1.80:1. This low age ratio probably resulted from migration of immatures to little-hunted areas before the September hunting season. The age ratio in the kill of white-winged doves was 1.78:1. Most hunters hunted within their county of residence. Hunter numbers and dove kill related closely to both human and dove populations.
