觀察細節
Single Motacilla Wagtail watched for around 10 minutes before flying north and continuing out of sight. Initial Identification made by typical Wagtail jizz, flight style and call. Plumage features showed a prominent supercilium, white outer rectrices and blotched yellow underparts. Grey Wagtail ruled out due to dark legs, relatively short tail, dark rump, brown back and call. Citrine Wagtail also ruled out by call, and lack of prominent wing barring. Additionally, both observers have experience with this species.
