Here are some great photos from Tammy Wolfe. She has some great behavior photos on her website of various bird species.

Below is a photo of a female hooder merganser removing an unwanted egg from her next box? I had no idea they were capable of doing that. For some reason I can't get my head wrapped around how they are able to grasp an egg with that thin bill. She must have pierced the egg.

In the spirit of checking the nest box, here is a photo of wood ducks that hatched from one of Tammy's boxes last year. Look close at all the young in the box.

Notice the little guy on the right with rosy orange cheeks? That's a hooded merganser chick. Somebody dumped and egg when the woody hen wasn't looking.

Great photos, Tammy, thanks for sharing!
