Subject: An interesting hybrid development
Laurie,
It does happen with birds. A good example is the problem arising in
Europe, where the American Ruddy Duck has started expanding its range
and has started interbreeding with the native White-headed Duck, which
was already endangered. This inter-breeding has exacerbated this
considerably, to the point that culls have been organised of the Ruddy
Duck. There is an informative page on Wikipedia about bird hybrids at
http://en.wikipedia.org/wiki/Bird_hybrid
Cheers,
Carl Clifford

I'm not sure whether this might happen with birds ...
