Birdwatch: One Flew Out of the Robin's Nest

We're back down to only two birdies! Yesterday afternoon we discovered that one of the babies has left the nest--successfully, we hope. I read somewhere that although they leave the nest after two weeks, they can't fly at first. But we didn't see any sign of the baby on the ground anywhere--so we hope he made it okay. Today was two weeks exactly since the first one hatched, so maybe he was ready!

As you can see, they've outgrown the nest--one has pushed the other into the surrounding pot, presumably because it's so hot outside and they're squished if they both sit in the nest!
