Pigeon Guillemot

Without an action shot of this species before this morning, I was stoked with this result. These guys are super cute, and I really like the pose since we can see the diagnostic white wing patch on the rear/left wing. Fortunately, my shutter was fast enough to freeze his high-frequency flapping.
