The common snipe (Gallinago gallinago) is a small, stocky wader native to the Old World. The breeding habitat is marshes, bogs, tundra and wet meadows throughout northern Europe and northern Asia. It is migratory, with European birds wintering in southern and western Europe and Africa (south to the Equator), and Asian migrants moving to tropical southern Asia. The North American Wilson's snipe was previously considered the same species, and is listed as such in older field guides.

Description

G. g. faeroeensis in Iceland
Gallinago gallinago – MHNT

Adults are 25–27 cm (9.8–10.6 in) in length with a 44–47 cm (17–19 in) wingspan and a weight of 80–140 g (2.8–4.9 oz) (up to 180 g (6.3 oz) pre-migration). They have short greenish-grey legs and a very long (5.5–7 cm (2.2–2.8 in)) straight dark bill. The body is mottled brown with straw-yellow stripes on top and pale underneath. They have a dark stripe through the eye, with light stripes above and below it. The wings are pointed.[2][3]

It is the most widespread of several similar snipes. It most closely resembles the Wilson's snipe (G. delicata) of North America, which was until recently considered to be a subspecies — G. g. delicata — of common snipe. They differ in the number of tail feathers, with seven pairs in G. gallinago and eight pairs in G. delicata; the North American species also has a slightly thinner white trailing edge to the wings (the white is mostly on the tips of the secondaries).[4][5] Both species breed in the Aleutian Islands.[2] It is also very similar to the pin-tailed snipe (G. stenura) and Swinhoe's snipe (G. megala) of eastern Asia; identification of these species there is complex.[6]

There are two subspecies of common snipe, G. g. faeroeensis in Iceland, the Faroes, Shetland and Orkney (wintering in Britain and Ireland), and G. g. gallinago in the rest of the Old World.

Ecology

G. g. gallinago at Keoladeo National Park, Bharatpur, Rajasthan, India.

It is a well camouflaged bird, it is usually shy and conceals itself close to ground vegetation and flushes only when approached closely. When flushed, they utter a sharp note that sounds like scape, scape and fly off in a series of aerial zig-zags to confuse predators.[7] They forage in soft mud, probing or picking up food by sight. They mainly eat insects and earthworms, also some plant material.[3]

The male performs "winnowing" display during courtship, flying high in circles and then taking shallow dives to produce a "drumming" sound by vibrating its tail feathers. This sound has been compared by others to the bleating of a sheep or goat; hence in many languages the snipe is known by names signifying “flying goat,” “heaven's ram,” as in Scotland by “heather-bleater”[7] and in Finnish the name taivaanvuohi, "sky goat". Common snipe nest in a well-hidden location on the ground, laying four eggs of a dark olive colour, blotched and spotted with rich brown,[7] which are incubated by the female for 18–21 days. The freshly hatched young are covered in dark maroon down, variegated with black, white and buff.[7] The young are cared for by both parents, each parent looking after half the brood, with fledging in 10–20 days.[2][3]

Conservation

Overall, the species is not threatened. Populations on the southern fringes of the breeding range in Europe are however declining with local extinction in some areas (notably in parts of England and Germany), mainly due to field drainage and agricultural intensification.[2]

The Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA) applies to the species. It is still hunted as a gamebird in much of its range.[2]

History

Old folk names include "mire snipe", "horse gowk", "heather bleat", and the variant spelling "snite".[8] See snipe for other aspects of the name.
