Many species have so called "hybridization zones" where actual, viable offspring tend to be found. Without the tendency to select for each other, like in the case of these new birds, you don't get speciation, pretty much by definition.

Don't recall. But coyotes and wolves have bred coywolves, which can themselves produce viable offspring.
