Always thought the Starling should not be able to do this, but on research, I was surpised to find that they are actually a 'Passerine Bird' so adept at perching, so like their smaller cousins, the tits, finches etc that eat my birdfood, these chaps with their brightly speckled feathers are also able to do so.
They are the teenagers of the UK garden birds, they arrive en-masse and will strip a feeder of all seed in a matter of hours.
