Hawks' Forbidden Love Results in a Rare Hybrid
She was a common black hawk. He was a red-shouldered hawk. They weren’t in the same genus, let alone the same species, and they normally don’t even live in the same part of the continent. But in a strange twist of fate, none of that mattered: It was love at first screech.
Researchers have discovered that two hawks from surprisingly distant perches on the tree of life have mated, resulting in rare hybrid chicks.
In 2005, Stan Moore, a master raptor bander at Fairfax Raptor Research, spotted something peculiar in the Laguna de Santa Rosa Wetlands Complex in Sonoma County, California. It was a common black hawk (Buteogallus anthracinus), a bird of prey definitely not known to inhabit coastal California. Normally, the species stayed close to river systems throughout Central and South America, only barely reaching up into the interior of the American Southwest. The nearest breeding population was in southeastern Nevada, hundreds of miles away.

Nice to see you over here! 
And this article is fascinating. Since the birds are so very different genetically, how did this mating produce a chick? They don't really answer that.
I hope someday that they will.
Now and then I get a glimpse of your success--Congrats!
