Guide to Boreal Birds
Long-legged Waders Overview
These cranes migrate in great flocks and assemble in vast numbers at places like the Platte River in Nebraska. Here it is possible to see what must have been a common sight when the species bred over most of the interior United States. The mating dance of the Sandhill Crane is spectacular. Facing each other, members of a pair leap into the air with wings extended and feet thrown forward. Then they bow to each other and repeat the performance, uttering loud croaking calls. Courting birds also run about with their wings outstretched and toss tufts of grass in the air.
Description
34-48" (86-122 cm). W. 6' 8" (2 m). Very tall, with long neck and legs. Largely gray, with red forehead; immature browner, no red on head. Plumage often appears rusty because of iron stains from water of tundra ponds.

A loud rattling kar-r-r-r-o-o-o.
Nesting
2 buff eggs, spotted with brown, in a large mound of grass and aquatic plants in an undisturbed marsh.
