Stork – Terran bird

Terran Storks are large, long-legged, long-necked wading birds with long, stout bills. They are the only family in the order Ciconiiformes, which was once much larger and held a number of families.

Storks dwell in many Terran regions and tend to live in drier habitats than the closely related herons, spoonbills and ibises; they also lack the powder down that those groups use to clean off fish slime. Storks have no syrinx and are mute, giving no call; bill-clattering is an important mode of communication at the nest. Many species are migratory. Most storks eat frogs, fish, insects, earthworms, small birds and small mammals. There are nineteen living species of storks in six genera.

Various terms are used to refer to groups of storks, two frequently used ones being a muster of storks and a phalanx of storks.

Storks tend to use soaring, gliding flight, which conserves energy. Soaring requires thermal air currents. Storks are heavy, with wide wingspans: the marabou stork, with a wingspan of 3.2 meters and weigh up to 8 kg, joins the Andean Condor in having the widest wingspan of all living Terran land birds.

Their nests are often very large and may be used for many years. Some nests have been known to grow to over two meters in diameter and about three meters in depth. Storks were once thought to be monogamous, but this is only partially true. They may change mates after migrations, and may migrate without a mate.

Storks' size, serial monogamy, and faithfulness to an established nesting site contribute to their prominence in mythology and culture.
