Nombre en español: Aguja Parda
Nombre en ingles: Hudsonian Godwit
Nombre científico: Limosa haemastica
Familia: Scolopacidae
El aguja café (Limosa haemastica), también denominada zarapito pico recto, aguja parda, becasa de mar, picopando canelo, barga aliblanca, aguja lomiblanca y aguja de Hudson, es una especie de ave Charadriiforme de la familia Scolopacidae propia de América, y divagante en Europa y Australia.
Descripción
Posee largas patas y el pico largo y algo curvado hacia arriba le permiten andar y alimentarse entre la vegetación alta sobre el limo, y vadear aguas que le llegan hasta el vientre, sumergiendo la cabeza y el pico.
Historia natural
En primavera, los machos ejecutan un vuelo de exhibición dejando ver las partes inferiores de sus alas, que son blancas con la mitad delantera negra. En invierno el plumaje pierde brillo, pero las alas y la cola mantienen su dibujo. La postura de huevos ocurre en América del Norte y luego emigran a América del Sur. Sus presas son insectos, gusanos y otros invertebrados. Anida en marjales, cerca de aguas abiertas y en estuarios.
Distribución
Durante el periodo reproductivo se distribuye localmente desde el noroccidente y sur de Alaska hasta la bahía Hudson. Inverna en la costa Atlántica del sur de Suramérica y la isla Chiloé en Chile. En Colombia ha sido registrada en la costa Caribe en la isla Barú y en la ciénaga de Cholón.
Hudsonian godwit
The Hudsonian godwit (Limosa haemastica) is a large shorebird in the sandpiper family, Scolopacidae. The genus name Limosa is from Latin and means «muddy», from limus, «mud». The specific haemastica is from Ancient Greek and means «bloody». An 18th century name for this bird was red-breasted godwit. The English term «godwit» was first recorded in about 1416–7 and is believed to imitate the bird’s call.
Description
Adults have long dark legs and a long pink bill with a slight upward curve and dark at the tip. The upper parts are mottled brown and the underparts are chestnut. The tail is black and the rump is white. They show black wing linings in flight. The legs and feet are bluish-grey.
Breeding
Their breeding habitat is the far north near the tree line in northwestern Canada and Alaska, also on the shores of Hudson Bay. They nest on the ground, in a well-concealed location in a marshy area. The female usually lays 4 olive-buff eggs marked with darker splotches. Incubation period is 22 days.[4] Both parents look after the young birds, who find their own food and are able to fly within a month of hatching.
Migration
They migrate to South America. These birds gather at James Bay before fall migration. In good weather, many birds make the trip south without stopping. They are vagrants to Europe, Australia, and South Africa.
They can perhaps be most easily seen in migration on the east coast of North America where they can be plentiful in migration in late July through early August.
Diet
These birds forage by probing in shallow water. They mainly eat insects and crustaceans.
Conservation history
Their numbers were reduced by hunting at the end of the 19th century.
