On the right is a piece of a branch drilled out to provide holes to put peanut butter in. My father in law made this about ten years ago. The birds and squirrels love it. On the left is a small suet holder. Currently the birds are eating a small suet cake every three days or so. I also have a bird bath adjacent to these to give the birds water and a place to bathe. Its great when I get 5-6 birds in there at one time splashing around to get clean.
