Behavior Cranes are isolated on their territories during the breeding season and gregarious during the non-breeding period.
All cranes are basically diurnal in their habits.
At night during the breeding season, cranes stay on or near their nests, brooding their chicks and standing guard against predators and other dangers. In the non-breeding season, cranes roost at night in more or less large flocks at traditional roosting sites. The non-breeding season pattern of feeding by day and roosting by night is universal. Roosting provides security for the flock and offers juvenile and single birds opportunities for pair formation. Crowned Cranes roost in trees.
