| Occurrence Remarks |
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. |

| Event Remarks |
Viewing Conditions: First 2 birds were seen in the morning about 8:45. Sunny. Birds NW of me in the top of a dead tree, little more than the full width of a road right-of-way away from me. The later individual was in a leafy hawthorn tree. [plus or minus] 20 feet NW of me in the afternoon. The alternating bright sun + patchy shade made observation tricky. 8.5x binoculars used. |
