Eider (Somateria mollissima)
Demoiselle Crane (Grus virgo)
Large diving duck with elongated, triangular head profile and short neck. Male: white upperparts and black belly, black cap and two light green patches at back of head. Females are mostly barred in brown. Differs from King Eider by extended feathering on light tipped bill, triangular head profile with less steep forehead and lack of v-barred flanks. Flying birds gives a more elongated impression than King Eiders.
Sound:Males call a typical, pleasant, clear, 2-3 second long "aaaooooooh". Starting on a low note, slowly ascending and ending on a descending note. Usually accompanied by the female "ga ga ga ga".

Smaller and more delicate than Crane. Front of neck and chest black, with long plumes. Immatures show only faint black markings on neck and head. Upper wing lacks pale patch close to alula, and show little contrast between secondary and primary coverts. Easily mistaken for Crane in flight if black chest is not visible. Identification by call then helpful. Wing beats significantly faster than in Crane.
Sound:Recalls Crane but timbre very dry, almost rasping and pitch higher.
