So I was finally able to capture a couple pictures of the papa bird feeding the baby chicks (the top and bottom photo). And second from the bottom is the mother bird keeping a watchful eye as usual. Their breed was also identified...House Finch (thanks Rita!). And the image below is a closeup of one of the babies...they have become so full and chubby--and full of feathers--in less than two weeks. I'm pretty sure there are four in the nest. The reason the pictures of the parents are somewhat blurry are that I've had to take their photos not only from a distance (they hear the camera turn on, I swear) but also through an unwashed window (I really do need to clean my windows). Anyhow, to see previous pictures of the birds--in chronological order--click here, here, here, and here.
