We have a Christmas wreath hanging on our front door that we have been unable to take down because House Wrens have been roosting there since Christmas. A few weeks ago they started building a nest wedged onto the metal hoop and between the wreath and the door. It's really well constructed - round inside and has some clear plastic on the inside. Yesterday there was an egg in there. They are not sitting on it yet. I decided to name the female Awreatha. Or maybe she spells it Aretha. Al Warfield
