Tweet of the Day is a series of fascinating stories about our British birds inspired by their calls and songs.
Kate Humble presents the grasshopper warbler. The reeling song of the grasshopper warbler sounds more like an insect than a bird. Like the paying out of an angler's line from a reel, the grasshopper warbler's song spills out from the bush or bramble clump in which he sits. You'll hear it most often at dawn or dusk in overgrown scrubby or marshy areas.
