Similar species

South African Shelduck, Australian Shelduck, and female Paradise Shelduck are all similar; they do not overlap naturally with Ruddy Shelduck, but care needs to be taken with escapes from captivity, particularly in western Europe. Hybrids between any of these four species can also occur as escapes or feral birds. Note the exact tone of the head colour and patterns in particular for distinguishing them.

Distribution

South-eastern Europe east to Lake Baikal and Mongolia. They are also in the Canary Islands (Fuerteventura), across north-western Africa and in the highlands of Ethiopia.

Their winter range extends to southern India and south-eastern Asia and China.

Taxonomy

Flight : note dark primaries and green secondaries ( clear in the leading individual )
