The Bird Nuts Posted January 7, 2019 Share Posted January 7, 2019 I'm thinking that's an intersex female Mallard. 1 Quote Link to comment Share on other sites More sharing options...

Tony Leukering Posted January 13, 2019 Share Posted January 13, 2019 Though it's certainly not definitive, I'd vote for an old female Mallard. Since the homozygous sex in birds, unlike in humans, is male, old females, apparently particularly in ducks, with declining female-hormone levels begin taking on male plumage patterns. 1 Quote Link to comment Share on other sites More sharing options...
