Eurasian Wigeon
Mareca penelope
This dabbling duck is 42–52 cm (17–20 in) long with a 71–80 cm (28–31 in) wingspan, and a weight of 500–1,073 g (1–2 lb). The breeding male has grey flanks and back, with a black rear end, a dark green speculum and a brilliant white patch on upper wings, visible in flight or at rest. It has a pink breast, white belly, and a chestnut head with a creamy crown. In non-breeding (eclipse) plumage, the drake looks more like the female. The female is light brown, with plumage similar to that of a female American wigeon.

Falcated Duck
Mareca falcata
Males and females have similar lengths at 46 to 53 cm (18–21 in). Their weight can range from 422 to 770 g (14.9–27.2 oz), with males weighing more than their female counterparts.
