Yes.Steve do they like millet ?
Might be a squirrel, might be sparrows and starlings. They can empty a feeder fast. Especially a smallish one. Is there any hulls underneath? Squirrels can/will fill their cheeks and run. Birds tend to drop a lot or eat at the feeder and leave the hulls.I think a squirrel discovered the feeder, filled it yesterday almost empty today. Darn
