| Re: Goose question
well I have seen numerous canada greylag crosses and I have seen a clear barnacle hybrid though its parentage was uncertain....
So it does happen outside of captivity - but these are birds that don't ever get to reach their native breeding territory where they would be amongst their own and geograpically or socially separated from other species. So this is is unlikely to happen with truly wild birds (which have gone back to their breeding territories) as upposed to feral birds (or perhaps damaged birds unable to fly back to breeding grounds) like the barnacles and greylags that are here in the summer.
Hormones are very powerful things no doubt about that!! |
