This crane feeds mainly on the seeds of grasses and sedges, waste grains, insects and a range of small vertebrates (8). Unlike other species of crane that probe the ground with their bills, the blue crane tends to take above-ground resources (6). Courtship involves a 'dance' in which the male chases the female, interrupted with leaps, bows and bouts of calling (6). Nesting occurs during summer, usually from September to February, and the typical nesting site is secluded grassland at high elevations. The eggs are laid in the grass or on bare ground (8). Nesting occasionally occurs in wetlands, in which case a platform nest of reeds is constructed (8). Two eggs are usually produced per clutch, and these are incubated for 30 to 33 days. The young become fully fledged after 3-5 months (8). Blue cranes undertake local migrations, moving to lower elevations in autumn and winter with their chicks. Flocking is known to occur throughout the year but is more common during the winter when large flocks of several hundred birds form (8).
