There’s a nest that I’ve been watching with baby blackbirds in it. They seemed to be doing well and were about ten days old. This morning, I went out and noticed the nest was empty, but there was no sign of a struggle or any sort of predator getting them. Is it possible that the mother could have moved the babies? I saw the mother taking worms up to a different section of the yard this morning. I’ve seen her take worms to the babies in the nest before, so I thought maybe she moved them. If not, what happened?
