Tweet of the Day is the voice of birds and our relationship with them, from around the world.

Chris Packham presents the New Zealand bellbird. In 1770, during Captain James Cook's first voyage to New Zealand, an extraordinary dawn chorus caught the attention of his crew "like small bells exquisitely tuned": these were New Zealand bellbirds. New Zealand bellbirds are olive green birds with curved black bills and brush-like tongues which they use to probe flowers for nectar. Like other honeyeaters, they play an important role in pollinating flowers and also eat the fruits which result from those pollinations and so help to spread the seeds. The well camouflaged bellbird is more often heard before it is seen. They sing throughout the day, but at their best at dawn or dusk when pairs duet or several birds chorus together. Their song can vary remarkably, and it is possible to hear different 'accents' in different parts of New Zealand, even across relatively short distances.
