The great snipe (''Gallinago media'') is a small stocky wader in the genus ''Gallinago''. This bird's breeding habitat is marshes and wet meadows with short vegetation in north-eastern Europe, including north-western Russia. Great snipes are migratory, wintering in Africa. The European breeding population is in steep decline.
The birds are noted for their fast, non-stop flying capabilities over huge distances. They can fly up to 97 kilometres per hour, with researchers finding little evidence of wind assistance. Some have been recorded to fly non-stop for 48 hours over . Their wings are not especially aerodynamic, lacking pointed tips, and they typically do not stop to feed despite having opportunities. The birds instead rely on stores of fat.〔
The voice is described as a faint ''yeah''. Mating display calls of groups can be heard at long distances (more than 300 m) and include a rising and falling series of chirping calls and accelerating clicking noises.
At dusk during the breeding season, the males display at a lek (arena), standing erect with chest puffed and tail fanned out. They may jump into the air, and will produce a variety of rattles, clicks, buzzes and whistles while displaying. Three to four eggs are laid in a well-hidden nest on the ground.
These birds forage in soft mud, probing or picking up food by sight. They mainly eat insects and earthworms, and occasional plant material. They are difficult to see, being well camouflaged in their habitat. When flushed from cover, they fly straight for a considerable distance before dropping back into vegetation.
At 26–30 cm in length and a 42–50 cm wingspan, adults are only slightly larger, but much bulkier, than the common snipe and have a shorter bill. The body is mottled brown on top and barred underneath. They have a dark stripe through the eye. The wings are broad, and a pale wingbar is visible in flight.
The great snipe is one of the species to which the ''Agreement on the Conservation of African-Eurasian Migratory Waterbirds'' (AEWA) applies.
== Fossils ==
Fossils of the great snipe have been uncovered in North Carolina, dating back to about 4.465 Ma ±0.865M. This suggests that the bird must have at some point relocated across the Atlantic Ocean.〔(【引用サイトリンク】url=http://paleodb.org/cgi-bin/bridge.pl?action=checkTaxonInfo&taxon_no=83481&is_real_user=1 )
