20-12-2015 JURONG, SINGAPORE - WHITE NAPED CRANE (Antigone vipio)


These cranes breed in northeastern China, northeastern Mongolia, and adjacent parts of southeastern Russia. Individuals in the western part of the breeding range will migrate south through China, stopping to rest at the Yellow River delta, then wintering in wetlands of the middle Yangtze River valley. Overwintering areas include the Demilitarized Zone that separates North and South Korea, as well as the Japanese island Kyushu, where there is an artificial feeding station outside the city of Izumi which they heavily rely upon. These birds prefer shallow wetlands or wet meadows within broad river valleys, near lake edges, and within lowland steppes or areas that are mixed forest-steppe. They feed nest, and roost in shallow wetlands and along the edges of wetlands, foraging in the adjacent grasslands or farmlands. While migrating and at their wintering grounds, they will use rice paddies, agricultural fields, mudflats, and other wetlands.


The White-naped crane is a social bird and is often found alongside other crane species within their range, such as Red-crowned, Hooded, Eurasian and Demoiselle cranes. A White-naped crane is diurnal and when foraging it digs into the soil with its long bill, to reach tubers and roots. This species is fairly territorial when digging and feeding. As with all cranes species, these cranes are often observed ‘dancing’: flapping their wings, tossing sticks and grass, jumping, running and bowing. These actions are part of courtship, but are also thought to relieve tension and reduce aggression. White-naped cranes start a flight by running along the ground, and taking off into the wind, quickly gaining speed, and lifting into the air, to fly with outstretched necks, while the legs trail behind. They use thermal currents whenever possible. They fly in a V formation during migration. They make high-pitched, penetrating calls.
