Baby Robins

There is a nest just outside the window where I work and there have been three baby robins in there. Last week they started to leave the nest. One by one they disappeared except for the last one. He sat up in the nest looking down and I'm sure thinking to himself, "That's a long ways down there to drop if I can't fly." The next thing I knew my coworker was telling me he was on the ground. He hopped around till his mother found him. I'm hoping he is still doing okay.
