BTO Bird ID - Yellow-coloured wagtails

When is a yellow wagtail not a Yellow Wagtail? These bright-coloured summer visitors are declining across much of their range and a frequent mistake is believing that any wagtail showing yellow in its plumage is this species. This video will help you separate individuals from the more widespread resident Grey Wagtail - which despite the name always shows yellow! - and even juvenile Pied Wagtails.
