Woodcock

The woodcocks are a group of seven or eight very similar living species of wading birds in the genus Scolopax. The genus name is Latin for a snipe or woodcock, and until around 1800 was used to refer to a variety of waders.[1] The English name was first recorded in about 1050.[2] According to the Harleian Miscellany, a group of them is called a "fall."[3]

Taxonomy

Only two woodcocks are widespread, the others being localized island endemics. Most are found in the Northern Hemisphere but a few range into the Greater Sundas, Wallacea and New Guinea. Their closest relatives are the typical snipes of the genus Gallinago.[4][5] As with many other sandpiper genera, the lineages that led to Gallinago and Scolopax likely diverged around the Eocene, some 55.8-33.9 million years ago, although the genus Scolopax is only known from the late Pliocene onwards.[6]

Woodcock species are known to undergo rapid speciation in island chains, with the extant examples being the Amami woodcock in the Ryukyu Islands and the several species of woodcock in the Indonesian islands, the Philippines, and New Guinea. Subfossil evidence indicates the presence of another radiation of woodcock species in the Greater Antilles; these Caribbean woodcocks may have been more closely related to the Old World woodcock species than the New World ones, and were likely wiped out by human incursion into the region.[7]

Description and ecology
American woodcock

Woodcocks have stocky bodies, cryptic brown and blackish plumage and long slender bills. Their eyes are located on the sides of their heads, which gives them 360° vision.[8] Unlike in most birds, the tip of the bill's upper mandible is flexible.[4][9][10]

As their common name implies, the woodcocks are woodland birds. They feed at night or in the evenings, searching for invertebrates in soft ground with their long bills. This habit and their unobtrusive plumage makes it difficult to see them when they are resting in the day. Most have distinctive displays known as "roding", usually given at dawn or dusk.[4][10][11]

The range of breeding habits of the Eurasian woodcock extends from the west of Ireland eastwards across Europe and Asia preferring mostly boreal forest regions engulfing northern Japan, and also from the northern limits of the tree zone in Norway. Continuing south to the Pyrenees and the northern limits of Spain. Nests have been found in Corsica and there are three isolated Atlantic breeding stations in Azores, Madeira and the Canary Islands. In Asia the sites can be seen as far south as Kashmir and the Himalayas.

Hunting

Some woodcocks being popular gamebirds, the island endemic species are often quite rare due to overhunting. The pin feathers (coverts of the leading primary feather of the wing) of the Eurasian woodcock are sometimes used as brushtips by artists, who use them for fine painting work.[12] The dog breed cocker spaniel is named after the bird, and were originally bred to hunt the woodcock.

Species

The following species of woodcocks are extant today:[4][11]

Fossil record

A number of woodcocks are extinct and are known only from fossil or subfossil bones.

  • "Scolopax baranensis" (fossil, Early Pliocene of Hungary; a nomen nudum)
  • Scolopax carmesinae (fossil, Early/Middle Pliocene? of Menorca, Mediterranean)
  • Scolopax hutchensi (fossil, Late Pliocene – Early Pleistocene of Florida, USA)
  • Scolopax anthonyi (prehistoric)[13]
  • Scolopax brachycarpa (subfossil, Holocene of Haiti)
gollark: Well, they have labels which look like `P/[random string]`.
gollark: Yes.
gollark: Does PotatOS do that? Huh.
gollark: Enjoy that in general, but don't enjoy that in this case as it does not apply.
gollark: Enjoy being wrong!
