Although more widespread in Scotland and Wales, come wintertime siskins are likely to be seen across the UK, many traveling from Europe to join the resident populations. They are a joyful sight, brightening even the dullest December day with their bright yellow plumage.
The siskin is a busy little bird with a distinctively forked tail and longish, narrow beak. The male (seen here) is marked by a black crown and bib. The female is more grey-green in colour.
Like other finches, siskins are seed eaters so you're likely to see them enjoying the seeds in conifer trees, or alder and birch woodlands where they gather in numbers during the winter months. If you're lucky you may get to enjoy them visiting your garden bird feeder.
