Spotless Starling (Sturnus unicolor)
Hen Harrier (Circus cyaneus)
Similar to Starling, and may be difficult to tell apart in winter and immature plumages. Most birds are in breeding plumage from March on, completely lacking spots, and with a purple (not green) sheen. Flight feathers lacks pale fringes, and the overall look is much darker than Starling. Elongated head and throat feathers are slightly longer than in Starling. Winter and immature plumage birds difficult to identify, but has small and spearhead-shaped spots, and darker wings (due to lack of pale fringes). Leg colour generally paler pink, than Starling, but some overlap occurs.
Sound:Similar to Starling in form and variation, but the long, descending whistling notes are more dominant and accented. Sometimes uttered as trills, or "stuttered". Whistles also used as contact calls when not breeding.

CCIn all plumages: Glides with wings raised in shallow V. Shows 5 primaries. This makes the wing tip broader than in Pallid- and Montague's Harriers, and the wings seems shorter. (Note that moulting individuals may show only 4 primaries). Male; grey with black primaries, white rump and underparts, and broad black trailing edge to underwing. Note that subadult males may show partly black primaries like Pallid. Female; brown with white rump, barred tail and streaked underparts.
Sound:Mostly heard at breeding ground. Calls with quite soft series of "ke-ke-ke-ke". Also a wailing, squealing whistle, with emphasized first syllable.
