Joanna We are east of you near cape Ann & our tube feeder is hung from a branch of a beech tree. It doesn't get dumped but sometimes the squirrels do get on it. they usually work on the spilled seeds on the ground. Ground feeders like Mourning Doves all work on the spills. Next year I am thinking about getting a tube with the screen bilt on so only the small birds can perch on it. The cardinals have been on the tube but are quite able to work on the ground. Every spring we have to clean the covers of the black oil seeds across the driveway that the chickadees dump. They grab the seed & fly off, different from the goldfinches which sit on the perch & eat & eat.
I don't use my digital camera very well & the window screens sort of block photos from inside.
