Grey Plover (Pluvialis squatarola)
Pallid Harrier (Circus macrourus)
Summer plumage unmistakable, with black underparts framed in white, with white and grey-speckled upperparts. Diagnostic in all plumages are the black armpits, which are clearly visible in flying birds. Also shows white wing-bars and very pale tail, with some barring. Winter-plumaged and juvenile birds speckled in grey with white underparts. Can be mistaken for Golden Plover. Especially the juveniles, which may have faint golden tone to plumage. Note instead heavier bill with swollen tip and bulkier body.
Sound:Contact call diagnostic. A plaintive, drawn and trisyllabic (but continuous) "kleeooowee". Pitch falls on second syllable and rises on last.

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".
