Had some guys working on the roof a couple weeks ago and noticed the beginning of a nest in one of the beams above the door. I initially took it down and threw it away but had a change of heart and put it back. I have been doing a lot of work on the house and have been in and out of the porch a lot lately. The last couple days the bird has been in the nest more frequently. She has gotten to the point where she doesn't fly away when I step on the porch now, unless I come towards her. Otherwise, she just sits there and watches me do whatever I'm doing.
