You will need:

Large pine cones 
Chunky peanut butter 
Corn Meal 
Shortening (or bacon fat, melted suet, etc.)
Bird seed and/or bread crumbs
Cake
String or yarn

Mix peanut butter, corn meal and shortening. Spread mixture thickly into the crevices
and all over the pine cone. Pour bird seed and/or bread crumbs into the cake pan. Dip
and roll the pine cone in the bird seed so that it sticks to the peanut butter and covers
the pine cone.

Let this harden overnight, then tie a piece of string or yarn to the very top of the pine
cone. Loop the string under the topmost "leaves" of the pine cone and tie a knot in the top. Hang the bird feeder on a tree branch in the yard, and watch the birds flock in!
