A. No, American Robins are the same species everywhere. But there IS a close relative that looks like a fancy robin, called the Varied Thrush, that lives in the coastal zone of Oregon north through the Pacific Northwest. A. Ornithologists do two kinds of DNA testing on birds. One is to figure out if all the baby birds in a brood are from the same parents. With robins this usually, but not always, is the case.
Scientists do another type of DNA testing to figure out which birds are related to which.
This kind of testing has shown that the robin family, Turdidae, is not as closely related to a group of tiny birds, called kinglets, as scientists once believed. For a while scientists thought that kinglets and robins were in the same family, but DNA testing proved that they weren't. The Varied Thrush looks a lot like a robin, but DNA testing and other methods have shown that it's not only a different species, it's also in a different genus. Their normal flight speed is around 20-32 mph. The fastest robin speed that I could find in my research books was 36 mph.
