Update

I went to check on the nest with 4 robin eggs that I took a photo of last Sunday. I saw blue shells on the ground under the nest and I didn't hear the parents squawking. Then the parents started up. I took a peek in the nest and got this shot and quickly left.

It appears all 4 made it to this point. Their downey feathers were still wet and their eyes are still closed. I've never seen anything like it. It seemed sacred to me. Hopefully when I go to check next week they will all have safely flown the nest.
