Loved the picture! I have a similar suet feeder that is surrounded by a
small cage made of the same material as the feeder with the same size
mesh. The chickadees (chestnut backed and black capped, both) go inside
it regularly. The have to do a little twist to get out, but they make
it easily.

I hung this feeder because the big birds dominate the suet feeders
otherwise, but I forgot about those long-billed woodpeckers who reach
right through the cage to the suet until the chunk gets too small. The
flickers, in particular, are daily visitors! Which is good: I love
watching the flickers, and I am so glad to find something that will keep
them breeding on my five acres.
