Our fat ball feeder is having some unusual visitors recently. The local male blackbird is using it quite frequently, as is at least one robin. What looks to be a juvenile blackbird is also trying to emulate the elder bird. I think we also have a warbler of sorts using it, but without any form of optics to allow me a closer look I can't be sure. Am I correct in assuming these all to be unusual?
This is how close I was able to get. Little ratty was totally oblivious to my presence.
