The Eurasian or common whimbrel (Numenius phaeopus), also known as the white-rumped whimbrel in North America, is a wader in the large family Scolopacidae. It is one of the most widespread of the curlews, breeding across much of subarctic Asia and Europe as far south as Scotland. This species and the Hudsonian whimbrel have recently been split, although some taxonomic authorities still consider them to be conspecific.

Taxonomy

The Eurasian whimbrel was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his Systema Naturae under the binomial name Scolopax phaeopus. [2] It is now placed with the curlews in the genus Numenius that was introduced by the French ornithologist Mathurin Jacques Brisson in 1760. [3] [4] The genus name Numenius is from Ancient Greek noumenios, a bird mentioned by Hesychius. It is associated with the curlews because it appears to be derived from neos, "new" and mene "moon", referring to the crescent-shaped bill. The specific epithet phaeopus is the Medieval Latin name for the bird, from Ancient Greek phaios, "dusky" and pous, "foot". [5] The English name "whimbrel" is imitative of the bird's call. [6]

Five subspecies are recognised: [4]

The Hudsonian curlew (Numenius hudsonicus) was formerly considered to be conspecific. The two species were split based on genetic and plumage differences. [4] [11]

Differences in species

The common whimbrel was traditionally considered a sub-cosmopolitan bird, breeding in Russia and Canada, then migrating to coasts all around the world to spend the winter. However the North American population of whimbrels was considered distinct enough to be considered a separate species from the common whimbrel. [12] In 2020, the New World population was recognised as a separate species, with the whimbrel in North America being assigned to the binomial name Numenius hudsonicus.

Whilst very similar at an initial glance, there are several features that distinguish whimbrel species in the Old and New World. In appearance, the New World species has a more “faded” appearance, with differences in the supercilium and crown. By far the most significant difference may be seen in the lower half of the bird. Whimbrels in Europe and Asia have a primarily white rump that can be seen in flight, while whimbrel in the New World have a rump similar in colour to the rest of the bird - drab brown with dark streaking. [13] As a result, whimbrel on vagrancy trips to North America may be known as the “white-rumped whimbrel”, while whimbrel vagrants from North America to Europe may be known as “Hudsonian whimbrel”.

When the context of their location is known, both species may be simply known as the whimbrel.

Description

The Eurasian whimbrel is a fairly large wader, though mid-sized as a member of the curlew genus. It is 37–47 cm (15–19 in) in length, 75–90 cm (30–35 in) in wingspan, and 270–493 g (9.5–17.4 oz; 0.595–1.087 lb) in weight. [14] It is mainly greyish brown, with a white back and rump (subspecies N. p. phaeopus and N. p. alboaxillaris only), and a long curved beak with a kink rather than a smooth curve. The usual call is a rippling whistle, prolonged into a trill for the song. The only similar common species over most of this bird's range are larger curlews. The whimbrel is smaller, has a shorter, decurved bill and has a central crown stripe and strong supercilia.[ citation needed ]

Distribution and migration

The whimbrel is a migratory bird wintering on coasts in Africa, and South Asia into Australasia. [1] It is also a coastal bird during migration. [15] It is fairly gregarious outside the breeding season. It is found in Ireland and the United Kingdom, and it breeds in Scotland, particularly around Shetland, Orkney, the Outer Hebrides as well as the mainland at Sutherland and Caithness.

Behaviour and ecology

Breeding

The nest is a bare scrape on tundra or Arctic moorland. Three to five eggs are laid. Adults are very defensive of nesting area and will even attack humans who come too close.

Food and feeding

This species feeds by probing soft mud for small invertebrates and by picking small crabs and similar prey off the surface. Before migration, berries become an important part of their diet. It has also been observed taking insects, specifically blue tiger butterflies [16]

Conservation

The whimbrel is listed in the Agreement on the Conservation of African-Eurasian Migratory Waterbirds . Near the end of the 19th century, hunting on the Eurasian whimbrel's migration routes took a heavy toll on its population, which has since recovered. [17] It is listed as Least Concern on the IUCN Red List and has been negatively impacted by climate change, habitat destruction and outbreaks of Avian flu to which it is susceptible. [1]

The whimbrel and the Hudsonian curlew are considered to be conspecific. [1] [18]

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.

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 is about 30 cm (12 in) long and fed mostly on insects and berries.

The bar-tailed godwit is a large and strongly migratory wader in the family Scolopacidae, which feeds on bristle-worms and shellfish on coastal mudflats and estuaries. It has distinctive red breeding plumage, long legs, and a long upturned bill. Bar-tailed godwits breed on Arctic coasts and tundra from Scandinavia to Alaska, and overwinter on coasts in temperate and tropical regions of Australia and New Zealand. The migration of the subspecies Limosa lapponica baueri across the Pacific Ocean from Alaska to New Zealand is the longest known non-stop flight of any bird, and also the longest journey without pausing to feed by any animal. The round-trip migration for this subspecies is over 29,000 km (18,020 mi).

The specific haemastica is from Ancient Greek and means "bloody".The English term "godwit" is believed to imitate the bird's call.

The slender-billed curlew is a bird in the wader family Scolopacidae. Isotope analysis suggests the majority of the former population bred in the Kazakh Steppe despite a record from the Siberian swamps, and was migratory, formerly wintering in shallow freshwater habitats around the Mediterranean. 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.

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.
