Storks


Storks have a dignified appearance, standing graceful and tall or marching deliberately on slender legs. Nature has a good purpose for those long legs, of course: they allow the stork to take long strides and wade into deep water or tall grasses and reeds in search of food. A long neck allows them to stretch out to capture their prey. Storks are also beautiful in flight. They fly mostly by soaring on warm air currents, with long, broad wings that only flap occasionally. They stretch their necks out and dangle their legs behind them as they fly, making them recognizable even from far away. Some storks have bare patches on their heads and necks. In the scavenger species, this is thought to prevent feathers from getting stuck together with blood or mud, but the bare places are also used to impress, becoming more brightly colored during breeding season. Some storks also use their feathers in displays, like the woolly-necked stork Ciconia episcopus that has feathers to puff out around its throat like a ruffed collar.
