Baby birds

These guys have been making quite the racket in the tree near the house. I could only see one of them in the nest, but I think I hear several. This one seemed hungry.

I've never seen mom or dad bird around, but they must be around somewhere, because these guys have been there for weeks now. I think they're probably just old enough to be emerging, because I've taken several looks in the past, and only this evening did I spy this guy poking his head out occasionally.
