Answer 2

network of rivers and streams drain the North Pennines creating a web of linear habitats of vital importance to birds and other wildlife.

A number of birds are closely associated with rivers and streams and thanks to this association are relatively easy to see.

The dipper is perhaps the most characteristic bird of upland rivers and streams. This medium sized, rather round bird can often be seen standing on a rock in the middle of a stream, bobbing a few times before popping under the water to forage for its favourite food, the caddis fly larva.

Dippers have a striking plumage, a deep brown head and back and a bright white breast. Often all that is seen of them, however, is a whirr of wings as they fly fast and low over the water emitting their high-pitched squeaking call. Being dependent on a rich supply of river invertebrates, the presence of dippers is an indicator of good water quality.
