Suet bird Feeder

These days we spend a lot of time watching birds enjoy their feeders in our garden. I think I could watch them for hours from the warmth of the kitchen table. I decided to venture making a suet block for them with leftover suet from our roast chicken dinner.
Mix any of the following together:
1 C flour
1/2 C suet (rendered fat)
1/2 C oats
1/2 C peanut butter
1/2 C nuts
1/2 C raisins
1/2 C bird seed
1/2 C any other dried fruit, nuts, seeds you have lying around.
Mush into a sort of paste with a spatula & dump it onto wax paper. flatten into a block shape with another piece of wax paper & refrigerate to harden.

We cut our block into 3 even squares to fit the suet cage we picked up at the local hardware store for $3.99. Since hanging it up we have seen myriad more varieties of birds, and many dark small ones that we can't yet identify.
