The black- billed stork ( Ciconia boyciana ), also known as the oriental white stork , is an endangered Asian walking bird species.

description

The 100–115 cm large black-billed stork can weigh up to 5 kg. It differs from the white stork ( Ciconia ciconia ), to which it is assigned as a subspecies by some authors, by its black beak and its overall more powerful appearance and size. In captivity, the oldest bird lived to be 48 years old. In addition to insects, fish and amphibians, it also eats small reptiles and mammals.

Occurrence

The black-billed stork breeds in northeast China and southeast Siberia on the Amur and Ussuri . He winters in southern China on the lower Yangtze , but also with a few animals in Hong Kong . During bird migration, the stork can also be seen elsewhere in China, Korea, and Japan. The habitat includes wet meadows and swamps with isolated trees.

Reproduction

The black-billed stork breeds in areas with forests, reeds and sedge meadows far from human settlements. Since this bird occupies a fixed territory, it is aggressive towards other species. He builds a single nest of dead twigs that is padded with grass on a tree that offers a view of the surroundings. The clutch consists of two to six eggs.

Duration

Endangered Species on Russian Postage Stamp (2007)

In 1994 the population was estimated at 2500 birds. The reasons given for the decline in stocks are the drainage of wetlands for agriculture, overfishing and human disturbance. Therefore, the bird is protected in Russia, China, South Korea, and Japan.

There is an international breeding program for the black-billed stork that specifically aims to reintroduce this species to Japan. Offspring in captivity have proven difficult because of the aggression of the male towards the female.
