Suet Soiree

Do you have leftover roasting grease (chicken, turkey, pig, beef) from the holidays? I had a ton and I re-use most of it but couldn't get the last layer out of the foil roasting pan. Plus a lot of it had terribly burnt bits. I decided to put a thin layer of wild bird seed over the grease and let the birds go to town in the backyard. I've never seen so many songbirds in my yard! They're out there having a ball, and bulking up for winter cold. Unless they all have heart attacks first.
