White-throated Swifts making a feeding stop above Arkansas River in CO
They sometimes flew quite close to the Arkansas River as they picked off the apparent abundance of insects on which they feed. Boy oh boy, do they move fast! Trying to get a reasonable photo was a real challenge. While not great (terrible back lighting so virtually no features) I think these photos show some interesting views of these highly skilled flyers.
These swifts stayed over, possibly grounded by the rainy weather last week, and I saw them several days more. SeEtta
