Dr. Todd,
Take a look at the citations in http://www.bird-hybrids.com/references.php?id=146&nomenclature=cinfosci. There's also Dilger, W.C., and P.A. Johnsgard. 1959. Comments on "species recognition" with special reference to the wood duck and the mandarin duck. Wilson Bulletiun 71:46-53. I also seem to remember apaper Paul published in the early 60's, I think it was in British Birds decribing a brood of hybrids at the Wildfowl Trust why he was working on hybrids. All reports I have seen say they're a nondescript bird and sterile.

"Clint- We are talking about a Goose being able to insiminate with a duck, CAN'T HAPPEN! U are talking about a certain kind of breed of duck mating with another breed of duck and come out with a hybrid mix. U cannot cross a species of one animal with another species. For instance, a human cannot insiminate a monkey and end up with a whole different mammmal (like a Hunkey) for lack of a better name for a non-exsistant entity. I am aware the the genetics of birds is very different than mammalian genetics (that obvious) But just because a bird has a different number of chromosomes does not mean it can morph into something else and breed."
You are confusing alot of terms there. You say "U cannot cross a species of one animal with another species". If that was the case you could not have a wood duckxmallard hybrid...or a mallardxpintail hybrid, which are fertile. And a breed mating with a breed doesn't produce a hybrid because they are the same species. You might want to take a look at Grant, P.R., and B.R. Grant. 1997. Genetics and the origin of bird species. Proc. Natl. Acad. Sci. 94:7768-7775.
There's also another paper that estimates 22 million years for reproductive isolation to arise in birds, but only 2 million in mammals.
