A. There are many choices of squirrel proof bird feeders that are designed to thwart them. However, the other creatures present a more difficult problem as they can knock a bird feeder down to the ground and really damage it trying to extract seeds.
The best solution is to use a baffle on any pole used or a hood over a hanging feeder. Also, it is a good idea to attach a hanging feeder well so the animal can't knock it down. If these animals are so clever that they are really causing problems, the only solution may be to bring the bird feeder in at night since most of these animals are nocturnal.
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.
