All I saw was a pile of black goo...and it had some red things mixed in with it. Have you even seen a halfway developed bird egg fall out of the nest and break? The stuff that wasn't black goo looked like that. But I didn't see any shells around. I washed it away with the hose the best I could.
The Robin on the front yard is gone. I found 2 eggs under the nest...one on the driveway and one in the grass. Both broken I don't know if the mom knocked them out or if maybe a squirrel did it...sad. I was looking forward to taking some pictures of the babies. he nest wasn't very far off the ground. And it was right beside the driveway so I could have stood on the bumper of my truck and got some good shots.
