Brett Westwood presents the aquatic warbler. The stripy aquatic warbler is streaked like the sedges it lives in and is the only globally threatened European perching bird. They sing in the marshes of central and eastern Europe where the small European population has its stronghold. Unfortunately, this specialized habitat is disappearing because of drainage, disturbance and peat extraction. They are migrants so it's vital to protect their wintering areas as well as their breeding sites. It's known that up to 10,000 birds winter in the swamps of North-west Senegal.
