Rock Ptarmigan (Lagopus muta)
Bonelli's Eagle (Aquila fasciata)
Slightly smaller and less heavy than Willow Ptarmigan. Overall greyer plumage, and a more delicate bill. Male summer with grey upperparts and white underparts. Female summer with browner upperparts than male. Both sexes completely white in winter plumage, except for black lores in males. Wings white and tail feathers black in all plumages in both sexes.
Sound:Call of male a very distinct "rrrrrrr", being a rattling rapid pulse of clicks, like running a stick along a picket fence. Female has similar sounds, but is higher pitched and not so coarse as male.

CCMedium sized eagle with long wings and tail. Pale base of outermost primaries in all plumages (lacking in Booted Eagle). Adults easily identified by dark greater coverts forming mid wing band on underwing, in combination with pale body and pale lesser coverts (variable). Tail clear cut (but not as pointed corners as in Booted Eagle) with broad terminal band. Back with diagnostic white patch (variable). Immature told from dark and medium morph of Booted Eagle by pale base of outer primaries, narrowly and evenly barred tail (bands reaching outer edge). The species show less fingered wings than many congeners, and long tail combined with small head may recall Honey Buzzard. Characteristic gliding profile with projected carpal joints and straight trailing edge of wing. Slight S-shape to trailing edge of wing when soaring. Flight agile and falcon-like.
Sound:Not very vocal, but may call at breeding ground. Commonest call a sharp, gull-like "kleeee", beginning with marked register-break followed by drawn-out note with fairly stable pitch, unlike most congeners.
