Storks

Order Ciconiiformes    Family Ciconiidae

The storks, which belong to the Ciconiidae family, are found worldwide in temperate or tropic climates. Those in temperate climates migrate to warmer places during the winter. They are large birds with especially long legs and bills. Even the smallest species is 70 cm (27 in) tall while the largest is over 150 cm (59 in) in height. Males larger than females.

Storks tend to use soaring, gliding flight, which conserves energy. They use thermals to soar to over 1200 meters (4000 ft), glide in the direction of travel, gaining elevation again with another thermal, etc. They gather into large flocks for migration. When in flight, almost all storks have their necks and legs extended giving them an elongated shape. The 3 species in genus Leptoptilos fly with the neck retracted like herons.

Storks are carnivorous, not a vegetarian among them. Most favor aquatic habitants where they can wade to hunt and eat, fish, small amphibians, reptiles, insect larvae and more. The marabou stork and the greater adjutant eat carrion and have bald vulture-like heads. The Abdim’s stork eats mainly locusts, caterpillars and other large insects; also reptiles, mice and more.

Some species are colonial breeds while other enjoy nesting in solitude. Most storks nests in trees; some on cliffs or buildings. The maguari stork’s nest is made of grass and reeds and constructed on the ground. That is the exception; stork nests are usually built with sticks then covered with twigs, vegetation, or mud.

Storks are nonvocal birds and usually silent. However, greetings are made upon nest arrival by rapidly opening and closing its beak so that a clattering sound is made. Some species have a pouch that amplifies this sound. The clattering greeting may be accompanied by accompanied by deep head bowing and neck stretching. Clattering sound can also be produced by the partners striking their bills together.

Habitat: Most of the species are wading birds implying they like the edges of ponds and lakes. Other wet areas they frequent for finding food: streams, rivers, marshes, swamps. flooded meadows. A few species prefer dry grassy meadows. Less typical habitats include dense temperate forests (European black stork), and rain forests (Storm’s stork).


Genus Anastomus
The openbills are large wading birds characterized by large bills, the mandibles of which do not meet except at the tip. The cutting edges of the mandible have a fine brush like structure that is thought to give them better grip on snails. This feature develops only in the adults. No agreement about why the mandibles are gapped; perhaps so more pressure can be applied at the tips. They nest colonially in trees.
