Well, these were the last two birds in the nest this past Saturday when we went to go look. Unfortunately, all four did NOT make it. We had a casuality at the top of the slide :( I try to forget about it because it makes me sad, but it's part of nature I suppose; survival of the fittest. These two actually flew away when we were down there; I think we freaked them out. That wasn't good, but they flew away successfully...phew! Although this experience with "our robins" was not as successful as the last time, we still enjoyed watching it take place right in our backyard!
There is more information about Robins here if you're interested; it really is amazing. Most hatch and are out of the nest in less that 2 weeks.
