Monotypic species

Genus

Storks are rather well represented in the world fossil record, although no comprehensive review of them has been attempted. The earliest records come from the Late Eocene of Egypt. After taxa incorrectly referred to this family were removed, the earliest named species became Palaeoephippiorhynchus dietrichi Lambrecht, 1930 (Late Oligocene; Egypt). The stork family (Ciconiidae) includes 17-19 species, depending upon which classification is followed. They are widely distributed, mainly in the Old World Tropics. Being large, conspicuous, and easily observed, storks are well known birds throughout their range. Several populations are threatened or endangered. The seven species of “typical” storks of the genus ciconia are all somewhat similar, with mainly black-and-white plumage and straight bills.

Physical charateristics

White storks are large, wading birds. They are covered in white feathers, except for the black primary feathers on their wings. They have long, sharp bills, and slender legs that are bright orange. Hatchlings and young have black bills and yellowish gray legs. Adults stand from 100 to 115 cm stall, with half of that height being made up by the legs. Their wingspan is 155 to 165 cm. Males are larger, on average, than females but both sexes are identical in plumage.

Habitat

White storks inhabit open wetlands, savannas, steppes, meadows, pastures, and agricultural fields throughout their range. They prefer areas with shallow, standing water that are not too cold or humid. Their habitat preferences coincide with human preferences for agricultural areas and settlements, resulting in a long-term commensalism. During the breeding season, white storks also seek out areas with suitable structures on which to build nests, especially sunny sites on tall trees or rooftops. They have also been known to nest on walls, stacks of hay and straw, ruins, chimneys, and artificial nesting platforms.

Reproduction

During the breeding season, the white stork often forms loose informal colonies; up to nine pairs have been seen on one single rooftop. The male and female will stay together for the whole season but do not migrate together; if they reform their partnership in successive years it is typically due to attachment to the nest site rather than each other. Males will often arrive first and vigorously defend the nest site from intruders. The subsequent arrival of the female will initiate a fascinating and intricate courtship display involving the male shaking its ruff and vigorously bobbing its head. The pair will then build a huge, complex nest, with some reaching over two metres wide and three metres deep. Made from sticks, grass and other foliage, the nest is situated high up off the ground, and completion of the nest is often signified by placing one leafy branch on the top of the nest. The female will lay three to five eggs of a chalky-white colour which are incubated for 33 to 34 days. The chicks are fed by both parents via regurgitation and will eat up to 60 percent of their body weight each day, until around nine weeks of age when the chicks leave the nest. The white stork is believed to reach sexual maturity at around four years of age and live for up to 33 years.

Feeding habits

Fish, frogs also amphibia, insects, snails, crabs and small reptiles, mammals and birds.
Usually forages in shallow water, catching prey with a sharp stab of bill.

Conservation

This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population trend appears to be increasing, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size is very large, and hence does not approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.
European white storks breed throughout Europe, North Africa, Asia Minor, and the Middle East, although they have a fairly fragmented distribution within that large area. Breeding populations have been extirpated from many areas of Europe historically. They migrate into tropical Africa, parts of the Middle East, and the Indian subcontinent during the winter.
White Stork status Least Concern

Migration

Migratory. Highly dependent on soaring and thus thermals, crossing deserts, but avoiding large bodies of water and extensive forests. Migration of European birds very well known; populations of race ciconia from SE Palearctic may winter mostly from Iran to India. Birds winter in India Sept/Oct-Mar/Apr; one stork ringed in Germany was recovered in NW India. Most migration takes place from mid-morning to early afternoon.
