Not hard to imagine a common ancestor of American and European goldfinches managed to make the hazardous passage across the Atlantic to found a colony on the other side that evolved different colors over time. A single member of the European species was recorded here in 1999, although possibly released or escaped from captivity.

They are common, with similar habits and belong to the same genus. But of the pair the American deserves the name as breeding males are cloaked in canary yellow and sooty black, whereas Europeans have only a yellow flash on the wings. Both delight the eyes, twittering with apparent joy as they pluck seeds from flower heads, deserving the collective noun, a charm of goldfinches.
