[Tweeters] Hybrids

[Nelson Briefer via Tweeters]

William Clark or anyone else cannot look at a photo of a bird and call it a
hybrid. You can start to think a bird is a hybrid if it looks as other
birds and the physical  zone or area is determined to hold hybrids. In
other words, a hybrid is not a hybrid, unless the bird is proven to be a
hybrid. One of the best ways to think the bird is a hybrid is if there is a
definite change in the structure of the bird, such as changes in the wing
length, tail structure, beak structure, also the feet and legs. Possibly, I
don’t know— the pattern and color change of a bird might not indicate a
hybrid, but might be a start into thinking the bird is a hybrid. Cheers -
