We have achieved hatching

I have a little patio out back. It has a little roof over it. About two years ago wind blew away most of the vinyl undersiding, revealing the beams. My father always said he'd help me fix it, but he never has. Anyway, this spring a pair of Robins moved in and built a nest. For the last two weeks I've enjoyed watching them tend the nest. The female spent most of her time incubating while the male would occasionally bring her food, but spent most of the time guarding the nest. Well, about ten minutes ago the nest suddenly got very noisy. Both birds are now busily gathering food for their new family. My cat has yet to notice, but has the window below the nest is one of his favorite spots to sit, I imagine they'll be driving him crazy very shortly.
