This is a great story. I would encourage you to go to their website, WoodstockSanctuary.org and read about it. This is a worthwhile organization not to mention a great story. The ducks apparently had never been in water before and it took some coaxing to get them to go in. Once they got over the initial shock of something so new, they started enjoying themselves! Very cute story.

Last night at 11pm, I was turning out lights and there was a chestnut-backed chickadee trying to get into my back door. I have a window in the top of the door and here is this little bird frantically trying to get in. So I let him in with the door left open and he flew up on top of the cabinetry, then around the light. I have a natural wreath of dried flowers and he landed on that. He was quite confused, flying all about. I should explain that this is my back porch so it was not like I was letting him into my whole house. Anyway, I decided to turn off the overhead light and turned on the outside light right outside the door and he flew right past me and out. I find this rather odd and have never had this experience before. I don't think of chickadees as nocturnal at all and why all the agitation. ...............................................................Anyway, thought I would share.
