Nuthatch

Tweet of the Day is a series of fascinating stories about our British birds inspired by their calls and songs.

Bill Oddie presents the nuthatch. Nuthatches are the only UK birds that can climb down a tree as fast they can go up and you'll often see them descending a trunk or hanging beneath a branch. Nuthatches are unmistakable: blue-grey above, chestnut under the tail and with a black highwayman's mask.
