- Rallus aquaticus
Identification
25–28 cm (9¾-11 in)
Upperparts olive-brown with broad, black streaks, grey face, breast and flanks, black-and-white barring on rear flanks, and greyish supercilium.
Similar species
Brown-cheeked Rail is very similar, differing in browner, less grey cheeks and flanks; it can usually be separated on range, but overlaps locally with Water Rail on their wintering grounds in southern Asia. Young juvenile Common Moorhen is sometimes mistaken for Water Rail by novice birders.
Distribution
Breeds throughout most of Europe except for the northern half of Scandinavia; also western and central Asia, and northernmost Africa. Western and southern populations are resident, while northeastern birds are migratory. Winters mostly within the southern and western half of the breeding range but also more widely in north Africa and southwestern Asia, and a few reaching east to India and southeastern China.
Taxonomy
Brown-cheeked Rail used to be included in this species as a subspecies1.
Subspecies
There are three subspecies1, 2:
- R. a. hibernans - formerly bred Iceland, wintered Iceland (around thermal springs) and Ireland; extinct c.1965 due to habitat loss and introduced American Mink1.
- R. a. aquaticus - Western Palearctic
- R. a. korejewi - Iran to north-western China; winters to India and southern China
Habitat
Reedbeds, marshes, etc.
Behaviour
A skulker, this bird is much more often located by its piglet-like squeals. Food includes both invertebrates and plant materials like seeds.
