Somewhere I have pictures of this from the beginning, but over the spring a robin made a nest in a bush off our deck. The robin laid four eggs, every day the girls would check on the nest. One of the eggs fell out of the nest shortly after we discovered it...not going to mention what happened to that egg. When we left on vacation there were three eggs in the nest and the mother robin was just keeping it warm. When we got back from vacation, only one egg was left and it had cracked open. The next day the baby bird was flopping around, it was hard to tell if it was going to make it, but every day they checked on the bird.
I wish this was more in focus but you could see him opening his mouth for food. Every day he got bigger and bigger, some days it was hard to tell because the mother robin still sat on him to keep him warm. Eventually he began looking like a mini version of the mom and today when the girls checked the nest he was gone. I don't know if they were excited or sad, we have seen this living science experiment right in our back yard. Very cool.
