A weight sensitive feeder closes access to the seed openings when a certain amount of weight is on the perch. You can calibrate to exclude birds such as starlings, red-winged blackbirds, grackles, etc. I did see a few clever starlings who learned if they continued to flap their wings while only partially applying their weight to the perch, they could poke their beak into the much narrowed slot to get a seed. However, it required effort and energy. Not many persisted. I have my feeder set to support cardinals and smaller birds. Good luck! Holly, Eaton Birding Society member
