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

The rasping repeated call of the corncrake was once a familiar sound of hay meadows throughout the UK. However these birds were no match for mechanical mowers which destroyed their nests and they're now mainly found in the north and west where conservation efforts are bringing them back to lush meadows and crofts.
