INCUBATION SHARING OF NORTHERN BALD IBIS (Geronticus eremita) PARTNERS

Özet

This study related out during the incubation period of northern bald ibises. Northern bald ibises in Birecik are free-living in nature during the breeding period (February–June) in 2013-2015. Pairs share the incubation between the two sexes. Females were incubated for 177.08 minutes per day on average while males were incubated for 240.99 minutes per day. This incubation period is statistically different (P 0.05). According to 2014 (n=128) and 2015 (n=88) results no statistical difference could be observed between incubation periods (P >0.05).The excess eggs during incubation are protected by northern bald ibises which do not have any nest (altruism). From time to time-synchronized behaviors can be observed in the population.
