This is another feeder that I made for certain birds that can hold on, sparrows don't get to it. One side of the roof lifts up to put the suet block in. I used a piece of an old leather belt for the hinges. You can see how I made it here. Upside Down Feeder
This type of feeder would be ideal for our Long tailed tits and our Great spotted woodpeckers. It would stop the starlings getting at the food inside.
