I spent a freezing cold but delightful couple of hours watching a Dipper diving in the shallow waters of the burn running through my local wood today.
Dippers are the only passerine (perching) birds which dive and swim underwater, in search of freshwater shrimp and insect larvae, and they have a transparent nictating membrane over their eyes to protect them underwater (see photo).
