Here's the same bird just before it took off. Kelly says it's an older female because of the few iridescent feathers on the top of her head.
The area near Terlingua/Study Butte is decorated for the season with red ocotillo blooms. Stunning!
This rascally Rufous Hummingbird is likely one Kelly banded a couple of years ago. He returns to the same location for the winter, but shuns the traps.
