How to identify
Scaup are diving ducks with a resemblance to Tufted Ducks. Males have black heads, shoulder and breast, white flanks, a grey back and a black tail. Females are brown, with characteristic white patches around the base of the bill. In flight, they show white patches along the length of the back edge of the wing. Only a handful breed in the UK every year, making them our rarest breeding duck. Key
