I think it may just support the weight of a Starling, but they have no finesse when it comes to landing and I think the momentum would cause it to shut. A Pigeon has no chance!
Seems a bit of a sneaky buy for someone who likes Squirrels, Starlings, Crows, Pigeons, Jays, Magpies - the list goes on !! But they do have their own table down the garden which is filled up most days

The 2 separate upper compartments store 1 pint of crushed peanuts EACH! The lower compartment has two and a half pints of sunflower hearts.
It is claimed to hold over 4 Lbs of seed, - just what I need as we get through loads of seed weekly!

I've just put it out as a New Years surprise for them tomorrow.
