(24) The breeding season of the Cranes in the North zone of latitude has a certain time period which differential to the species in the South zone that has breeding season depending on the rainfall (23) and most nesting on the wetland. (25) From the observed of Walkinshaw, found the nesting of Sarus Crane built on before laid eggs about one week and the average territories per a pair is 40.47-60.70 hectares or 100-150 acres. (26) Their clutch average is two eggs and lay apart not over than 48 hours (27) which are incubated by both sexes for about 31-36 days. Usually, the female are incubate in the night which flip the eggs many times for a day and has communicated with the male by unison call. The chicks will be hatch within one or two days after the incubation period and live together with the parent until to 8-9 months before separated in the next breeding season. (23) These juvenile cranes come to living together after the separated for feed and rest until to eighteen months before have the courtships displays, develop the calling of guard calls and unison calls for mating in the next time.
