We have a European Goldfinch visiting our balcony birdfeeders. The default assumption is that he's an escape from domestic captivity, because its natural range isn't exactly close to here, but it's acting wild, hanging out with a mixed flock of Common (American) Goldfinches, Redpolls, and House Finches, and it arrived with an Arctic air mass. We're hoping that experts can establish its subspecies from pictures, because if it's from a Northern one (rather than, say, the subspecies particular to Sicily, Corsica, and Sardinia), it might be judged a genuine wild bird way out of its range.
If so, the trickle of interest we've had for visiting our viewing area may get rather more substantial!
