I love birds and got several feeders a few years ago. The problem is the squirrels liked them, too! I got this feeder with a landing shelf than would automatically close when something too heavy (a squirrel) got on it. If a bird got on it, it stayed open and the bird had access to the seeds.
I would watch these squirrels climb up the pole and get on the side of the landing shelf..Not on it! They would take their paw and manipulate it in a way that they got to the seeds. Amazing. I swear they are smarter than some of the homeowners we have here in our development! How do I know this to be a fact you ask? Well, I am a Board member(Homeowner’s Association).
