Appearance:

Occurs in dark and pale morph. Plumage recalling gulls more than shearwaters (especially pale morph). Differs from shearwaters in white or pale head, compact body, short and heavy bill and broad wings. Flight pattern distinguishes it from gulls, and is similar to other tubenoses. Glides on stiff wings with occasional bursts of shallow and stiff wing-beats. Pale base of primaries visible at considerable distance in both dark and pale morph. Dark morph most common in high-arctic areas, pale morph most common in southern breeding range.

Sound:

Mostly heard on breeding ground. Coarse, harsh, staccato calls when courting or quarrelling.

Appearance:

A medium sized, brown and long-winged owl, with long ear-tufts and deep orange eyes. Only half the size of Eagle Owl. Differs from the more similar Short-eared Owl by darker (orange) eyes, longer ear-tufts and heavily streaked lower belly. In flight, note paler wing-tips (only finely barred, not tipped black).

Sound:

Song a series of very deep, monotonous "hooooo"s, quite widely spaced. Uttered about once every 2-3 seconds. Sometimes rises in pitch, but with each "hoo" being constant. Rich repertoire of calls. Other sounds include; a nasal "eeeeeaaa" reminiscent of Collared Dove, nasal mewing and bill clicking.
