Blue-winged Teal Spatula discors x Cinnamon Teal Spatula cyanoptera hybrid
Both species were formerly placed in the genus Anas.
This can be a naturally-occurring hybrid in both North America where both species are common but is also frequent in captivity.
This tame bird undoubtedly originated in captivity (Blue-winged Teal is a very rare vagrant in the UK and Cinnamon Teal hasn't been accepted as occurring here naturally, though it probably has; both parent species are popular in captivity). It was seen displaying vigourously, sometimes on its own, sometimes with Mallards but most often to a female Mandarin.

It was such a lovely bird I couldn't help but go back for seconds...
