Re: Baer's Pochard

["Tim Murphy" <>]

I must admit to extreme ignorance in what hybrids are possible. Can someone
tell us?  How far across phylogeny can a viable offspring occur. Inside
genera yes but outside genera and inside family? (Yes I know these are
artificial)?

I once saw a bird in British Columbia which had the marks of a Mallard /
Merganser cross which I would have thought pretty unrelated - still Sibley
and Alquist place them in the same Tribe and Sub-family.
