I am located in West central NJ and have 3 hanging bird feeders and several cage style suet feeders in operation. I have fed the wild birds ever since we moved here in 1965. With the upsurge in Coopers and Sharpshin populations I feed far less than I initially did. This year I have one interesting finding. There are no blue jays coming to my feeders. None at all. Has anyone else noticed a decrease in the blue jay population in their area, or is it just here.
