The long-billed curlew (Numenius americanus) is a large North American shorebird of the family Scolopacidae. This species was also called "sicklebird" [2] and the "candlestick bird". The species breeds in central and western North America, migrating southward and coastward for the winter.

Description

The long-billed curlew is the largest sandpiper of regular occurrence in North America. It is 50–65 cm (20–26 in) long, 62–90 cm (24+1235+12 in) across the wing and weighs 490–950 g (1 lb 1+12 oz – 2 lb 1+12 oz). [3] Its disproportionally long bill curves downward and measures 11.3–21.9 cm (4+128+58 in), and rivals the bill of the larger-bodied Far Eastern curlew as the longest bill of any shorebird. [4] Individuals have a long neck and a small head. The neck and underparts are a light cinnamon in color, while the crown is streaked with brown. This species exhibits reversed sexual dimorphism, as in many sandpipers, the female being larger and having a much longer bill than the male's.

Breeding

The breeding habitat is grasslands in west-central North America. The species displays an elaborate courtship dance, with fast and looping display flights also being common. A small hollow is lined with various weeds and grasses to serve as the nest. The species is a determinant layer, a characteristic of shorebirds, laying four eggs, which vary in hue from white to olive. The young of the Long-billed curlew are precocial, the chicks leaving the nest soon after hatching. Though both parents look after the young, females usually abandon the brood to the male 1–3 weeks after hatching and depart for winter grounds. [5] Adults whose nest fails often depart immediately (or nearly so) for winter grounds. [5]

Feeding

Long-billed curlews often feed in flocks. Using the long bill, an individual probes the mud or other substrate for suitable food. The usual food consists of crabs and various other small invertebrates. The species also feeds on grasshoppers, beetles, and other insects. This bird has been known to occasionally eat the eggs of other birds.

Conservation status

The population was significantly reduced at the end of the 19th century by hunting, though numbers have rebounded somewhat in more-recent times. The species was formerly classified as Near Threatened by the IUCN, but new research has confirmed that the long-billed curlew is again common and widespread. [6] Consequently, it has been downlisted to Least Concern status in 2008. [7]

Candlestick Point in San Francisco was named after this indigenous bird, and subsequently Candlestick Park stadium inherited the name. [8] The species had dramatically declined in the San Francisco area by the early 20th century already, being "practically extinct" in San Mateo County in 1916. [9] By the time the stadium was constructed in the 1950s, there was no remnant of the huge, local flocks of "candlestick birds" left. [8]

The long-billed curlew was also formerly a plentiful wintering bird on the East Coast of the United States, and John James Audubon's painting of the species was in fact of individuals he sighted near Charleston, South Carolina. However, market hunting and breeding habitat loss nearly wiped out this population, and presently only a small "ghost" or relict population of less than a hundred birds still winters on the East Coast, and this population has yet to recover. It is possible that this wintering population may have consisted largely of now-extirpated birds that bred on the eastern Great Plains, and the disappearance of those birds may tie in to the near disappearance of the Atlantic wintering population, with the present Atlantic wintering population being the descendants of the last survivors of the eastern Great Plains breeders. In December 2015, one such "ghost bird" was successfully captured off the coast of Georgia and fitted with a satellite tag with plans to analyze its migration routes, with it taking flight in April 2016.

Scolopacidae is a large family of shorebirds, or waders, which mainly includes many species known as sandpipers, but also others such as curlews and snipes. The majority of these species eat small invertebrates picked out of the mud or soil. Different lengths of bills enable different species to feed in the same habitat, particularly on the coast, without direct competition for food.

<span class="mw-page-title-main">Curlew</span> Genus of birds

The curlews are a group of nine species of birds in the genus Numenius, characterised by their long, slender, downcurved bills and mottled brown plumage. The English name is imitative of the Eurasian curlew's call, but may have been influenced by the Old French corliu, "messenger", from courir , "to run". It was first recorded in 1377 in Langland's Piers Plowman "Fissch to lyue in þe flode..Þe corlue by kynde of þe eyre". In Europe, "curlew" usually refers to one species, the Eurasian curlew.

The Eskimo curlew, also known as northern curlew, is a species of curlew in the family Scolopacidae. It was one of the most numerous shorebirds in the tundra of western Arctic Canada and Alaska. Thousands of birds were then killed per year in the late 1800s. As there has not been a reliable sighting since 1987 or a confirmed sighting since 1963, the Eskimo curlew is considered Critically Endangered or possibly extinct. The bird was about 30 cm (12 in) long and fed mostly on insects and berries.

This species has occurred as a vagrant in western Europe, the Canary Islands, the Azores, Oman, Canada, and Japan. The slender-billed curlew was always a rare species and is feared extinct, with the last verifiable sighting being in 2004.

<span class="mw-page-title-main">Far Eastern curlew</span> Species of bird

The Far Eastern curlew 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. The body is reportedly 565–1,150 g (1.246–2.535 lb), which may be equaled by the Eurasian curlew. 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.
