Squirrels are funny. They aren't suppose to like that stuff. I brought the upside down feeder and attached it directly to the tree hoping to make it more difficult. They can do it. I catch them nibbling. I put food on the ground for them so they should be satisfied, right?. I see them out eating the suet and now I just open the door and scold them, say hey and they run down. Sometimes they run behind the hedge wait a minute and come back and eat on the ground. I think they are trying to pass themselves off as a different squirrel. LOL
I brought a caged suet feeder. It is round cage and has the suet in the middle. The squirrels cannot get in it at all. . I see mostly Downey in that one but occasional will see a Flicker.
