Scientific classification
Kingdom: Animalia Phylum: Chordata Class: Aves Subclass: Neornithes Infraclass: Neognathae Superorder: Neoaves Order: Charadriiformes Suborder: Scolopaci Family: Scolopacidae Genus: Scolopax Linnaeus, 1758
Diversity
7-8 living species

The woodcocks are a group of seven or eight very similar living species of wading birds in the genus Scolopax. Only two woodcocks are widespread, the others being localised island endemics; most are found in the Northern Hemisphere, but a few range into the Wallacea. Their closest relatives are the typical snipes of the genus Gallinago.^[1]

Description, ecology and use by humans

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 almost^[specify] 360° vision.^{[citation needed]} Unlike in most birds the tip of the bill's upper mandible is flexible.^[2]

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.^[3]

All woodcocks are popular gamebirds; the island endemic species are often quite rare already due to overhunting. The tiny feathers that are located at the first joint of the woodcock's wings are referred to as "pin feathers" and are much esteemed as brushtips by artists, who use them for fine painting work.^[4]

Species

The following species of woodcocks are extant today:^[5]

• Eurasian Woodcock, Scolopax rusticola
• Amami Woodcock, Scolopax mira
• Bukidnon Woodcock, Scolopax bukidnonensis
• Dusky Woodcock, Scolopax saturata
  • New Guinea Woodcock, Scolopax (saturata) rosenbergii
• Sulawesi Woodcock, Scolopax celebensis
• Moluccan Woodcock, Scolopax rochussenii
• American Woodcock, Scolopax minor

Fossil record

A number of woodcocks are extinct and are known only from fossil or subfossil bones. Due to their close relationship to the Gallinago snipes, the woodcocks are a fairly young group of birds, even considering that the Charadriiformes themselves are an ancient lineage. Gallinago and Scolopax diverged probably around the Late Miocene some 10-5 million years ago.

• "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)
• Puerto Rican Woodcock, Scolopax anthonyi (prehistoric)
