Bluebirds

As we were leaving the Great Swamp National Wildlife Refuge in New Jersey yesterday after a snowy picnic, and a distant owl sighting, and the company of a crowd of very noisy bird photographers (interested only in dramatic owl pictures but not in the other birds around them, apparently), we noticed a small flock of bluebirds beside the road. 

No one else was about, and they were hunting. So we waited, and watched.
