Dippers (Cinclidae) and Waxwings (Bombycillidae)

Cinclidae (Dippers): Waterbirds found in fast-flowing streams in hilly terrain. Highly adapted to life in and around water. They are excellent divers and use their wings to return to the surface. They hardly use their legs underwater, but are able to walk along the riverbed whilst submerged.

Bombycillidae (Waxwings): Three species found worldwide, one of which is found in Europe. They have soft, silky plumage, long wings and a rounded tail. Short, sturdy feet and legs. Powerful, direct flight. Waxwings whistle and produce trills, but do not really sing. They are generally found in flocks during the winter.
