Popis: Wildlife managers depend on accurate information regarding wild turkey (Meleagris gallopavo) survival patterns to properly manage turkey populations. Survival patterns of male Rio Grande wild turkeys (M. g. intermedia) have not been studied intensively. Wildlife managers in the Texas Panhandle, USA, and southwestern Kansas, USA, suspected that turkey populations were declining. From January 2000 through August 2002, we studied survival and movement of 107 juvenile male and 115 adult male radiomarked Rio Grande wild turkeys on 4 study sites in the Texas Panhandle and southwestern Kansas. We predicted that males would experience lowest survival during spring and that there would be no difference in survival between age classes. We also predicted that greater male movement rates would lead to lower survival rates. Juvenile males had a higher annual survival rate (0.597 [95% CI hereafter: 0.478–0.716]) than adults (0.364 [0.257–0.472]). Juvenile male survival did not differ among seasons, with surviv...
