We got a new bird feeder and it is guaranteed to be squirrel proof, following the instructions and all! It makes me laugh out loud, because we have 2 squirrels here that are very at home and THEY are UNABLE to get to this feeder! It is marvelous! It is meant for small birds UP to the size of a cardinal and we have all these sweet birds coming to eat here and the squirrel is stuck cleaning up the ground! The curved posts are weight sensitive and collapse at anything heavier than a cardinal AND the length is calculated for the reach of the red/brown/gray squirrels and it works!!!!!!! Heeeheh! Very funny! See his dismay!!!!!!! :0)
