67% of the blacks that I shot this season were hybrids.

a mallard will mate anything that stands still or is moving very slowly....

The Black Duck is slowly being bred outta of existence.
The pic is a bit blurry, does the head have green in it? Or what is your clue this is a hybird?
Just trying to learn about all the details that make a black/mallard hybird.

White bar at the bottom of the speculum

looks like pure black duck from picture...however it isn't a very good picture. White on bottom of speculum is ok. White on top of speculum is sign of mallard hybridization.

True black ducks can and will have some white on the lower speculum.

The problem is not drake mallards mating with hen black ducks, its the blacks mating with the hen mallards. Mallards tend to prefer to stay with their own kind, the black ducks will stool on mallards though.

Thanks Dan I was waiting for somebody to catch that ....Figured I would've gotten chastised by pointing out that his statement was incorrect....

It's a bad pic but there was green in the head. It was a Cape May County bird. I usually get 2 or 3 hybrids each season. Third or fourth generation hybrids are not as obvious as first generation. I also shot a few banded hybrids years ago. One was banded in Canada.

Thanks for the link. It is very informative. I am surprised that CT hybrids count towards the mallard limit. In NJ they count towards the black duck limit. The ID of many of my hybrids were confirmed by USF&WS biologists during the
annual Wingbee.
