Green Woodpecker

Tweet of the Day is a series of fascinating stories about our British birds inspired by their calls and songs. Kate Humble presents the green woodpecker. The maniacal laughing call, or 'yaffle', of a green woodpecker was supposed to herald rain, hence its old country name of 'rain bird'. You can hear their yodelling calls in woods, parks, heaths and large gardens throughout most of the UK. Altough green woodpeckers do nest in trees they spend a lot of their time on the ground, probing lawns and meadows for their main food, ants and their pupae.
