I live in Western Connecticut.
This year we just had a chickadee family make a nest in one of our birdhouses.
The babies were just born a couple days ago and this morning we found total
devastation. The babies are gone but one of the parents was killed and ripped apart and bird wings left on our deck and the nest ripped apart and dumped on our deck as well.

I cried like a baby when I found this lovely little family destroyed. We had so been enjoying watching them painstakingly make their nest and the chirping of the new babies and we were waiting for them to grow and leave the nest. I kept leaving cat hair on the deck because I read many birds use hair to make nests and hair was mixed in with the twig nest.

Does anyone know what could have done this. I found that maybe house sparrows could do this.
Any experiences?

Thanks, Diandra
