Scientific name: Motacilla cinerea
Size: Approximately 18cm long. Wingspan approximately 26cm
Distribution: Found throughout most of the UK
Months seen: All year round, but scarce in eastern areas in summer
Habitat: Close to water, especially fast flowing rivers and streams
Special features: Grey wagtails have predominantly grey plumage on their upper parts and yellow plumage below. The legs are orange-brown and the beak is grey.
As the name suggests they frequently flick their tails up and down when on the ground. They have a long tail which accentuates this 'wagtail' action.
Grey Wagtails are sometimes confused with Yellow Wagtails (see link below).
