Hi Cobirders

I saw a dark phase Ross' Goose at Rocky Mountain Lake Park this afternoon. No grinning marks.It was on the south side, near the shore, with many Cackling and Canada geese. This is Denver County.

Thank you, Bob Canter, Denver

Hi Cobirders

I say this goose again today on the grass at Rocky Mt.Lake Park, Denver. To ID it as a hybrid, a hybrid of what?

Thank you, Bob Canter, Denver

I think cackling with ross given it’s small size.
A blue morph ross looks like it would have a hood and much darker body with extensive white markings on wings I think.
I searched ross/cackling hybrid on ebird and it looks very similar to the bird at the park.
Still a very rare bird and cool to see!
