Species of bird From Wikipedia, the free encyclopedia
The Far Eastern curlew (Numenius madagascariensis) is a large shorebird most similar in appearance to the long-billed curlew, but slightly larger. It is mostly brown in color, differentiated from other curlews by its plain, unpatterned brown underwing. It is not only the largest curlew but probably the world's largest sandpiper, at 60–66 cm (24–26 in) in length and 110 cm (43 in) across the wings.[3] The body is reportedly 565–1,150 g (1.246–2.535 lb), which may be equaled by the Eurasian curlew.[4] The extremely long bill, at 12.8–20.1 cm (5.0–7.9 in) in length, rivals the bill size of the closely related long-billed curlew as the longest bill for a sandpiper.[3]

In 1760 the French zoologist Mathurin Jacques Brisson included a description of the Far Eastern curlew in his Ornithologie based on a specimen. He used the French name Le courly de Madagascar and the Latin Numenius madagascariensis.[5] Although Brisson coined Latin names, these do not conform to the binomial system and are not recognised by the International Commission on Zoological Nomenclature.[6] When in 1766 the Swedish naturalist Carl Linnaeus updated his Systema Naturae for the twelfth edition, he added 240 species that had been previously described by Brisson.[6] One of these was the Far Eastern curlew, for which he coined the binomial name Scolopax madagascariensis.[7]
The Far Eastern curlew spends its breeding season in northeastern Asia, including Siberia to Kamchatka, and Mongolia. Its breeding habitat is composed of marshy and swampy wetlands and lakeshores. Most individuals spend the non-breeding season in coastal Australia, with a few heading to South Korea, Thailand, Philippines and New Zealand, where they stay at estuaries, beaches, and salt marshes. During its migration the Far Eastern curlew commonly makes stopovers on the mudflats of the Yellow Sea.
It uses its long, decurved bill to probe for invertebrates in the mud. It may feed in solitary but it generally congregates in large flocks to migrate or roost. Its call is a sharp, clear whistle, cuuue-reee, often repeated.
On its breeding grounds the Far Eastern curlew consumes insects, such as larvae of beetles and flies, and amphipods. During migration it also feeds on berries. In the non-breeding season, it consumes marine invertebrates, preferring crabs and small molluscs but also taking other crustaceans and polychaetes.[1]
As of 2006, there are an estimated 38,000 individuals in the world. Formerly classified as least concern by IUCN, it was found to have been rarer than previously believed and thus its status was uplisted to "vulnerable" in the 2010 IUCN Red List of threatened species.[1]
In Australia its status under the Environment Protection and Biodiversity Conservation Act is "critically endangered".[8]
Its population decline has been linked[9] to the massive tidal flat reclamations by China, North Korea and South Korea along the coasts of the Yellow Sea, which have caused a greater than 65% loss of mudflats[10] where the Far Eastern curlew makes stopovers.[9]
