The pointed beak makes this bird expert at extracting seeds from thistles, and feeders with niger seeds – which is where we often see them in the back garden. They were once called thistle finches. It took me a long time to recognise goldfinches, because I was expecting something a bit more… gold!
Wikipedia reports that “In Britain during the 19th century many thousands of goldfinches were trapped each year to be sold as cage-birds.” Thank heaven this practice of caging wild birds is no longer acceptable in the UK; some other parts of the world have yet to catch up.
Apparently, many goldfinches are resident in the UK but some migrate further south in winter, as far as Spain – just like many retired Brits.
