Seen quite regularly around Clevedon but have only very rarely seen them on my feeders.
No interactions present.
The difference between the sexes is not great but most pronounced at ths time of year - this one is richly coloured with bright wing flashes, so is almost certainly a male.
This is a great photo, it's certainly a greenfinch from the olive-green colour and the yellow wing streaks.
