Been trying to come up with a custom platform feeder for my trees. I have ringneck dove’s and unfortunately a neighbor of outdoor and feral cats. Trying to come up with a way to feed the larger bird’s where the cats can’t get to them. Also have blue bird’s, Robins, wood Peckers plus a few other larger bird’s
I have the tube feeders for my smaller birds like finches, chickadees sparrows and a few others I haven’t been able to find in the bird pictures. Just need input on what type of feeder would be best to customize and the best place to locate them away from all of the seems to be rapidly multiplying felines. I live in Orem Utah which is pretty much in the center of the State.
