I'm uploading my original sketch of this record (no photos available) in order to reference it in an eBird checklist. The observation was made in Boot Canyon, Big Bend National Park, Brewster Co., TX. The sketch was redrawn later (2nd image) for submittal with further details to the Texas Bird Records Committee. It was later accepted as the 3rd record for Texas (TBRC 1989-22, Amer. Birds 36:994).
