Our feeder is mostly visited by sparrows and tits and nuthatches, with the occasional magpie swooping in and scaring them all off. Bigger birds such as jays and magpies don’t like the new feeder much – I guess it swings and sways too much for their taste.
Occasionally a gang of goldfinches flies in. They’re rarely on their own; they seem to travel in groups.
Greenfinches have the opposite habits. I’ve never seen more than one here at the same time.
