灰瓣蹼鷸 Grey Phalarope

學名: Phalaropus fulicarius

英名: Grey Phalarope

Family : Phalaropodidae (瓣蹼鷸科). Length: 20-21cm.



Grey phalarope breeds in western North America and migrates to South America, with lobed toes and a straight, slender bill. The red phalarope (Phalaropus fulicarius) is an unusual wading bird, not just because it spends up to 11 months of the year far out at sea, but also because the female is larger than the male and displays more flamboyant colouration during the breeding season. During this time the female has large white cheek patches, a black crown that extends past the black-tipped, yellow bill, and a chestnut red neck and chestnut underparts. The wing uppersides are black, although the buff edges of each feather give a streaked appearance, and the legs are pale blue.

When feeding, a phalarope will often swim in a small, rapid circle, forming a small whirlpool. This behavior is thought to aid feeding by raising food from the bottom of shallow water. The bird will reach into the center of the vortex with its bill, plucking small insects or crustaceans caught up therein.
