Are they there?

I have seen the robins flying around with what very well may be bugs and other protein sources in their mouth, so I wondered if the baby robins hatched. When I went outside and lurked near the nest I did not see or hear any babies. I googled for information, and didn't find any for sure, but it seems that maybe baby robins don't make noise, at least at first. And I can't actually see into the nest. I'm not willing to agitate the parents by getting my step ladder and climbing up to look.

Since I couldn't get any cute robin pictures, I took one of the saxifraga in bloom.
