Another feature that is claimed to be diagnostic for separating Ash-throated from Great Crested is the wing feather edges. On Great Crested the tertial edges are bright white contrasting with gray edges on the secondaries and coverts. On Ash-throated all these feathers have edges with similar contrast. Dave Czaplak's (http://www.odolep.com/abirdhome.htm) excellent description and photos make a good case for this bird being an Ash-throated Flycatcher. However, they also suggest the possibly that the wing pattern may be somewhat more consistent with Great Crested. See the right-hand photo in the second row and sketch 1. So I have two questions 1) Are there other examples of this wing pattern not matching the bird? 2) Can anyone who saw the bird comment on what the wing pattern looked like in the field? Photographs can be misleading.
