My bird feeders have been overrun by starlings and grackles, so I bought this one with tiny perches. It’s supposed to keep the bigger birds out because it’s difficult for them to perch and eat.
Well, guess who the first visitors were? Yes, starlings & grackles. They perch precariously and lean over to eat out of the adjacent port.
Well, they have to eat, too, and I must give them an “A” for being so inventive.
