Stupid bird!

We have the interior demo work 100% complete. We have a floor plan selected. We have windows selected and ready to order. I have almost decided on an exterior color. We have the house clean (well, as clean as it's going to be in this stage). We are totally ready to pull off the back mud room from the house. We've been ready for a week. However, one little bird refuses to leave the nest (I realize he was born in 2010, but he's a gen x'er at heart). We watch the mom come and literally try to pull him out. He looks outside and heads back to the nest. We have been more than generous. He has to fly by tomorrow or my goodwill towards him is gone.
