Siberian Crane - Behaviour and Ecology

Behaviour and Ecology

Siberian Cranes are widely dispersed in their breeding areas and are highly territorial. They maintain feeding territories in winter but may form small and loose flocks, and gather closer at their winter roosts. They are very diurnal, feeding almost all through the day and their migration is done When feeding on submerged vegetation, they often immerse their heads entirely underwater. When calling, the birds stretch their neck forward. The contexts of several calls have been identified and several of these vary with sex. Individual variation is very slight and most calls have a dominant frequency of about 1.4 kHz. The unison calls, duets between paired males and female however are more distinctive with marked differences across pairs. The female produces a higher pitched call which is the "loo" in the duetted "doodle-loo" call. Pairs will walk around other pairs to threaten them and drive them away from their territory. In captivity, one individual was recorded to have lived for nearly 62 years while another lived for 83 years.
