Curlew
Rust curlew (Numenius americanus)
The curlews (Numenius ) are a genus of the family of the Waders ( Scolopacidae ). They are characterized by a long, narrow, slightly curved beak and a plain brown plumage with no major seasonal changes. The closely related godwits are distinguished by their straight beak.
Curlews feed mainly on insects, worms and other invertebrates that they are looking for with their long beak in marshy soils, but also of berries. An unusual for curlews food spectrum shows the very rare bristle curlew. He also eats lizards, small ground mammals and carrion, as well as the eggs of sea birds, which he occasionally wegpickt even among breeding birds. Usually break bristle curlews on the shell by letting the eggs fall to the ground. Bristle curlews were also at it observed that they dropped stones on the eggs. On their long journeys, they show high flexibility in the diet, the bristle curlew has been observed to plunder Seevogelnestern.
Species
- American curlew or rust curlew ( N. americanus), breeds in the prairies of North America and draws in the winter to the southern coast of the United States, Mexico and occasionally into southern Central America; still unchallenged, but stocks going back
- Curlew ( N. arquata ), widely used in Europe and Asia, overall because of the large and stable Asian stocks safely, in Germany highly endangered
- Eskimo curlew ( N. borealis) breeding bird of the Canadian tundra, pulls in winter to South America, may already be extinct. Last confirmed evidence in 1963 in Barbados, since repeatedly unconfirmed observations. The species counted until the 19th century the most common birds in North America, but was decimated by extremely strong hunting
- Isabellbrachvogel ( N. madagascariensis ), breeding bird in eastern Siberia and Mongolia, moves in the winter to Southeast Asia and Australia, but stocks going back more safely
- Dwarf curlew ( N. minutus), breeding birds in Siberia, winter overcoat to northern Australia, safely
- Whimbrel ( N. phaeopus ), breeding bird in the sub-Arctic regions of Europe, North America and Asia, wintering in Africa, South America and South Asia, safely
- Bristle curlew ( N. tahitiensis ), breeding bird in western Alaska, Winter Overcoat to Oceania, endangered
- Slender-billed Curlew ( N. tenuirostris ), breeding birds in Siberia, wintering in the Mediterranean. In the 19th century a very common type, extremely declined sharply due to strong hunting and destruction of wetlands in the wintering areas and highly threatened with extinction.
