We were away for five days. Before we left I had been bringing in big bowls of blueberries every day, but I took the netting off while we were gone to let the birds have their share.
When we got back there was not a berry left on any of the four shrubs. We obviously had some happy birds while we were gone. I also saw the chipmunk sitting on the tree stump that is near the blueberries -- he probably had something to do with stripping the bushes.
I had harbored some fears that the black bear would discover the blueberries, but there was no evidence of a big berry eater anywhere, so I think it was just a bonanza for the birds and some good snacking for the chipmunk.
I'm glad they enjoyed them when we couldn't.
