This flock was about o.5 miles from me when I took this shot. This is just a fraction of the entire flock. It really looked like a tornado as the birds were going to roost in some cattails.
I travel to Potlatch every day for work. Where did you see this flock of swallows? I've noticed several along Hwy 1 at the fish pond prior to the intersection with Hwy 4. I'd love to see them!
