I'm pretty sure all the rest have left - the little lady is probably waving goodbye with a last stop at the lantana to boost her on the way. They are a bit fatter than earlier this summer!
Wow, this is a gorgeous shot! I love the position of the Hummingbird, and the lovely background really makes the bird stand out. From the look of those spots on the throat, seems like this is a young male on its first migration!
@janetb Thanks, Janet, for that identification hint - hadn't realized until you mentioned it that the young ones look alike until the first winter. So much I learn here.
Great action shot.
