Key information
The high, insect-like reeling song of the grasshopper warbler is the best clue to its presence. Even when you hear one it can be difficult to locate it due to the ventriloquial effect of its singing. If seen on migration it moves like a little mouse, creeping through the foliage. Dramatic population declines have made this a Red List species.
