Description
Size: Length: 37-41 cm.

Color: Drake recognisable by his pink-brown white-speckled head, with conspicuous broad white eyebrows, and bluish grey on wing and shoulders. Duck closely resembles female Common Teal (Anas crecca) but is paler. In flight, her very indistinct speculum as compared with the Teal's is suggestive. At close range the pure white throat (instead of brown-speckled) and the prominent superciliary stripe distinguish her. Breeding male vermiculated grey flanks, dark back, mottled brown breast; Head, neck and breast dark chestnut brown with paler mottling on breast and cheeks; bold white eyebrow stripe from above eye to nape; wing blue-grey, primaries darker, speculum green with white trailing edge above. Female and eclipse male brown with wide pale edges to feathers giving mottled appearance; distinctive white eyebrow and white loral patch; speculum green; belly white in all plumages. Immature like female but with spotted belly. Bare parts: iris dark or umber brown, grey in immature; bill black or grey; feet and legs dull olive grey.

Habits: Along with the Common Teal, one of our earliest migrants, commencing to arrive by August. Very similar to it in habits. Also a swift flier and a good sporting and table bird.

Nesting: Season- in the Palaearctic Region (N. Europe to E. Siberia), May/June. Nest- a depression in the grass in wet meadows, sometimes lined with a layer of finer grasses but always with plenty of down feathers. Eggs- 6 to 12, buffy white with a glossy texture.
