Not in my experience. I put up a four perch feeder on a tree in myfront yard. A squirrel reached over to feed from it.
I chased it away. The birds still came at feeding time to eat. I just wish there was a way to keep the House Sparrows away from it.
They are so aggressive when they feed. Attacking each other and the Cardinals that I do attract I extended the feeder out more to keep the acrobatic squirrel out and taped off three of the perches. This kept the crowding down and the cardinals have more to eat when they come now Eddie, Detroit, Michigan.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
