I left a cup of water and a little bird seed our for the mamma bird. It has just been so hot here, I want to make her food hunting as easy as possible for these little guys. I love peeking in on them each time I go in and out of the house. All I have to do is stand on my tiptoes on my welcome mat and I see them resting. I'm a little worried because I haven't see a forth beak since yesterday. Maybe he is just really smart and learned I'm human and not going to feed him.
