Tweet of the Day is a series of fascinating stories about the British birds inspired by their calls and songs.
Michaela Strachan presents the long-tailed tit. They are sociable birds and family ties are vital. They even roost together at night, huddled in lines on a branch, and this behaviour saves lives in very cold winter weather. The nest of the Long-Tailed Tit is one of the most elaborate of any UK bird, a ball of interwoven moss, lichen, animal hair, spider's webs and feathers.
