Ah, Migration, I love you so. Driving around on my bird survey route, I see a ton of red-tailed hawks perched on power poles. The other day as I approached a pole I thought, "Oh hey, that's not the chunky red-tailed hawk shape I know..."
Sure enough, it was a hatch year peregrine falcon (and banded at that).
Alas the bird was not thrilled to have a scope on it and it flew after a few photos so I was unable to get the band numbers.
But a random and unexpected peregrine falcon among corn fields is always fun to find.
