The North American Green-winged Teal (Anas carolinensis) was formerly considered a subspecies of ''A. crecca'' but most authorities consider it as a separate species.

  Changed :) - I think with DNA testing these days we may see a lot of "new" species. Looks like Cornell still needs to catch up. I've been using the All About Birds website ( http://www.allaboutbirds.org/guide/search ) for my bird IDs. I like that it lists and compares similar birds. Posted 10 years ago, modified 10 years ago

    This is the divergent evolution.
    Cornell use the American Ornithologists' Union Checklist of North American Birds which does not recognise Anas carolinensis as a separate species. Here's a list of who does and who doesn't.

The Green-winged teal

The green-winged teal is a common and widespread duck that breeds in the northern areas of North America except on the Aleutian Islands. It was considered conspecific with the common teal for some time but the issue is still being reviewed by the American Ornithologists' Union; based on this the IUCN and BirdLife International do not accept it as a separate species at present. However, nearly all other authorities consider it distinct based on behavioral, morphological, and molecular evidence.
