Robin sized birds that breed in western and southern parts of the UK. Females lack the male’s black head, but have brown backs and an orange tinge to their chests.
Birds are frequently seen flicking their wings while perched, often doing so on the tops of low bushes. As its name suggests, birds utter a sharp loud call that sound like two stones being tapped together. It can usually be found on heaths, conifer plantations or coastal sites feeding on a diet of invertebrates, seeds and fruit.
