Our first uncommon visitor of the season.

Bufflehead at Green CayThe Bufflehead is the smallest diving duck in North America. It breeds primarily in Canada and winters in the United States. A female Bufflehead has been spotted over the last couple of weeks at Green Cay and this past weekend I was finally able to spot it and get some pictures good enough for positive identification. If you’re looking for this duck, it looks very much like a grebe with a white cheek. You’ll need a good pair of binoculars as she does not come close that often. I’m hoping that changes with time and that she’ll become friendly to visitors like the Eared Grebe last winter.

As birds go the Bufflehead has a couple interesting behaviors. Unlike other ducks the Bufflehead is usually monogamous, remaining with the same mate season after season. This duck also nests almost exclusively in holes made by Northern Flickers and Pileated Woodpeckers; a great example of how one species heavily relies on another for success.
