INCUBATION SHARING OF NORTHERN BALD IBIS PARTNERS

The study was carried out during the free-flying period. Pairs share incubation between two sexes. In observations made 2013 and 2015 (n=79 in day). Females incubated for 177.08 minutes per day on average while males 240.99 day. This period is statistically different (P< 0.0001) withmales staying 23-32% longer than females. stayed together only a short time. According to made(n=79), couples stay nests 20.52 average. During all long it realized that eggs are left alone 0.40 average.Incubation periods did not vary according years. (n=100) nest were of years 2014 (P>0.05). (n=128) (n=88) results no statistical difference could be observed (P >0.05).The excess protected by northern bald ibises which does have any (altruism).
