Citrine Wagtail (Motacilla citreola)
Pallid Harrier (Circus macrourus)
Adult male easily recognized with all yellow head with dark edges and grey back. Prominent white wing-bars and all dark bill, lacking the pale base of Yellow Wagtail. Females and adult winter lacks the dark lore-stripe of Yellow Wagtail, and the flanks are grey. The same applies to the juveniles. These also give a very grey impression, almost resembling a Pied Wagtail without the dark breast-pattern. Juvenile Yellow Wagtails have a less grey and more olive tone to their backs. The dark facial markings/earcoverts of females/winter/juveniles birds are usually framed by the continuation of the strong supercilium. Some Yellow Wagtails are very similar to Citrine, and call and tail length should be considered as well (tail longer in Citrine).
Sound:Contact call resembles Yellow Wagtail, but is harsher with a more buzzing quality, and of shorter duration. The pitch is more constant, lacking the rise and fall of Yellow Wagtail. The song is a loose repetition of phrases, comprised of disyllabic or monosyllabic contact calls.

Slender and elegant harrier, with narrow wings and four "fingers". Adult male easily recognized by very pale grey and white plumage, with diagnostic wedge-shaped, black wing-tips (outermost primary grey). Female and immature birds often difficult to tell from Montagu's Harrier and Hen Harrier. Adult female differs from Montagu's by lack of dark band on upper wing, and by diffuse, sooty inner underwing. Pale bands do not reach wingpit, and under coverts are darker. Differs from female Hen Harrier by noticeably slimmer wings (both hand and arm) and only 4 fingers (but beware moulting Hen Harriers). Immature similar to Montagu's with unstreaked, rufous underparts. Differs in pale tips of inner primaries, and dark half-collar and pale "boa".
Sound:Some calls similar to Montagu's and Hen Harrier, but display call quite diagnostic. A thin, vibrating trill "peerrrrrrrr".
