Brolgas typically found in large noisy flock (sometimes 1,000 or
more ) in a herd Each family group led by a man . When the rainy season
ends they may have to fly long distances to find food . Brolgas can search for cold air to fly to high altitudes . The Brolga
is found mostly in the tropical north or in the east of Australia is
difficult to estimate the numbers in Australia , but is said to range
between 20,000 and 100,000 conegrate They prefer freshwater marsh meadow
, but can survive in marginal brackish and salty wetlands.

Brolgas are gregarious creatures; the basic social unit is a pair or small family group of about three or four birds, usually parents together with juvenile offspring, though some of such groups are unrelated. In the non-breeding season, they gather into large flocks, which appear to be many self-contained individual groups rather than a single social unit.
Within the flock, families tend to remain separate and to coordinate their activities with one another rather than with the flock as a whole. When taking off from the ground the flight is ungainly, with much flapping of wings. The bird's black wingtips are visible while it is in the air and once it gathers speed, its flight is much more graceful and it often ascends to great heights. Here it may be barely discernible as it wheels in great circles, sometimes emitting its hoarse cry.
