Appearance:

Only eagle in WP with whitish underparts and dark hood and chest. Underparts variably barred with 2-3 tail-bands, but leaves an overall pale impression. May be confused with Osprey, but outer wing is much broader and carpal patches is absent. Dark individuals may resemble Honey Buzzards, but note 6 fingers and lack of carpal patches. Pale individuals may show pale throat and chest. Soars on flat or marginally raised wings, with hand stretched slightly forward. Tail slender with straight cut end and sharp corners.

Sound:

Quite vocal, especially at breeding ground. A wailing "keeeeaaaaaa" with marked register breaks, or a soft "pjuu-pjuu-pjuu". Male purer and more resonant than female.

Appearance:

Large gull with deep chest, light grey back and heavy yellow bill with red spot (adult). Pinkish legs and black tipped primaries with white windows. Winter plumage with streaked head and neck. Develops grey mantle in 2.nd winter. Young birds may be difficult to distinguish from juvenile Greater- or Lesser Black-backed Gulls, and the species shows notable variation in both plumage and size. Juveniles generally shows darker head and less contrasting markings than Greater Black-back, and pale inner primaries (window), as opposed to the all black hand of young Lesser Black-backs.

Sound:

Quite vocal. A long and strong "ay-kay-kay-kay-kay" with fading strength commonly heard. A deep "ga-ga-ga" heard from anxious birds. All calls much deeper pitched than Common Gull. Difficult to distinguish from Lesser Black-backed Gull, but tone is less nasal.
