Habitat: Breeds on variety of fresh and brackish waters, preferring lakes and ponds (even quite small ones) in forests, pools in taiga bogs or mountain willows, also along rivers and shallow, well-vegetated seashores, and on eutrophic, lakes if near forests, where nest is placed. A common bird, forming large flocks on coastal bays or shallow lakes outside breeding season. Birds from N Europe winter in Britain, but also in Holland, France, etc.

Identification: Smallest duck, with narrow, pointed wings, short neck, fast and agile flight and dense flock formation; takes off from water easily and rises steeply, will twist and turn readily in flight. At distance in flight, appears dark with short, broad white bar along centre of upperwing (both sexes). Speculum glossy green.

• Adult ♂ breeding: Head chestnut with green sides, green colour thinly bordered yellow. Sides of undertail pale yellow, bordered black, visible even at distance. Horizontal white line along grey body. Told from N American Green-winged Teal by this horizontal white line (Green –winged has vertical band across breast-side), and by complete thin yellow lines on sides of head.
• Adult ♀: Brown, streaked and mottled dark. Swimming bird resembles Garganey, but note: small size; small bill, often a little orange at base; moderately dark eye-stripe and lack of dark stripe over cheeks make head look fairly plain; a pale patch or streak along base of tail-side; chin/throat not so clean and pale buff-white. In flight told by wing pattern; belly diffusely paler at centre; underwing has whitish centre and dark leading and trailing edges.
• Eclipse ♂ and juvenile very similar to adult ♀, juveniles generally slightly darker (also on belly), and flanks more ‘striped’ dark (adult ♀ has more delicate scaly pattern).
