About a week ago I dug out the home made log feeders which have peanut butter in holes for birds to dig out. The intention being to try attracting more visits from a Great Spotted Woodpecker. It took most of the week before anything was bold enough to try them out and then it was the Starlings which have started visiting in larger, greedy, squabbling numbers.
Remember - if you are going to put out some peanut butter use an unsalted variety. Most of that made for human consumption has added salt which is bad for the birds.
These are the two varieties I have used.
