The documentation form by Barbara L. Wilson is the only one submitted and forms the basis of this record. | Elimination of similar species: these are Rose-breasted Grosbeaks or Blackheaded Grosbeaks. Or hybrids. Unfortunately, the identification depends on things I do not know. Ruth Green informs me that some Rose-breasted Grosbeaks in early September are so orange on the breast one would think them Black-headeds. Are these young Rose-breasted? What about the call? Do Rose-breasted Grosbeaks make a lower-pitched call, more mellow than the distinctive high-pitched call that is the only one I know for them? If you know, please tell me. These were odd-looking grosbeaks but I can't really identify them. | The original documentation form events occurred around 08:45:00 and in the afternoon.
