Assessment of the incubation period for each sex of Turkish semiwild Northern Bald Ibis (Geronticus eremita)

The semiwild population of Northern Bald Ibises (Geronticus eremita) at Birecik, Turkey, are the final representatives of the Eastern population of the species in the Middle East, apart from a few captive birds in Turkish zoos. This study took place between 2012 and 2015. Breeding is highly synchronized among the colony and incubation behavior was monitored for multiple nests throughout the day. Differences were found when incubation duty period was examined according to sex. In 2013, the incubation period varied significantly between males and females (F = 71.059, P
