@birdfactofficial: A robin's song is one of the loveliest sounds in a British garden. In winter, the lyrics are mostly threats. Robins sing almost all year round. From autumn, males and many females hold their own winter territories, and song is how they keep rivals off. That's why you still hear them when many other garden birds have gone quiet. Some even sing at night, next to street lights. #robin #birdsong #ukbirds
