Bufflehead Duck

Day 25 / 365

Freezing my bum off for an hour in one spot today paid off.    🙂

Interesting Fact: Buffleheads are highly active and will undertake dives almost continuously. One duck will serve as a sentry, watching for predators as the others in the group dive in search of food. ( http://www.withmephotographyblog.com/10-interesting-facts-about-the-bufflehead )
