Cloebird Posted January 3, 2019 Share Posted January 3, 2019 I was going to post this photo under “Sexual dimorphism in Birds” as male & female Greater Scaup. Or do I have a male Greater and a Lesser? Seen in May at Reed Lake SK. Quote Link to comment Share on other sites More sharing options...
The Bird Nuts Posted January 3, 2019 Share Posted January 3, 2019 I think the peaks at the back of their heads make them all Lessers. Quote Link to comment Share on other sites More sharing options...

Cloebird Posted January 3, 2019 Author Share Posted January 3, 2019 Okay, thanks for the input. I was trying to make a rounded head out of the middle duck. Quote Link to comment Share on other sites More sharing options...
jcarscadden Posted January 3, 2019 Share Posted January 3, 2019 I too would have thought the middle scaup was differente.... head seems smaller - less of a forehead and eye differently placed in head - BUT it may all be camera angle and would not disagree with BirdNuts 1 Quote Link to comment Share on other sites More sharing options...
