Appearance:

Chocolate-brown hood in adult plumage (seemingly black at a distance), but head only with dark markings in winter and juvenile plumages. Underparts of inner primaries dark grey. First few primaries white with black tip, both on upper side of wing and under. Last character conspicuous in all plumages, but slightly less obvious in juveniles due to larger dark area of wing-tip. Slender-billed Gull and Bonaparte's Gull show similar white first primaries, but differs in long and slender head profile and white underparts of hand respectively.

Sound:

Quite vocal, especially at breeding ground. Distinct, harsh calls. A rasping "kreearr", and shorter, sharp warning calls; "kek".

Appearance:

A medium sized owl, which can give a very pale impression in flight. Quite similar to a Long-eared Owl with folded tufts, but differs in bright yellow eyes, darker wing-tips and heavily streaked breast in contrast to pale belly.

Sound:

Song: a series of 6-10 deep "ho"s evenly spaced. Much faster than long eared owl, and rising in pitch until the final "ho". Calls: a raspy, drawn, mewing "eeeeeeeeeah" (about 2 seconds), rising in pitch with accented ending.
