Female or sub-adult male Rufous Hummingbird: Randell Davey Audubon Center, Santa Fe, New Mexico, July 2023 — There were all most as many of these birds at the Randell Davey Audubon Center in the foothills above Santa Fe as there were full adult males, though they were not “guarding” feeders. I am sure some of them were females, but some were probably sub-adult males. OM Systems OM-1 with 100-400mm zoom at 800mm equivalent. Program mode with my custom bird modifications. Processed in Pixelmator Pro. ISO 250 @ f6.3 @ 1/640th.
