Great Grey Shrike (Lanius excubitor)
Leach's Storm Petrel (Hydrobates leucorhous)
Light grey upperparts, black wings and tail with white patches, white underparts and throat. Broad, black eyestripe not reaching above highest point of bill. Bill long and medium heavy (not as heavy as in Lesser GS). White patch at base of primaries varies according to subspecies. Black part of tail most narrow at base. Juveniles less pure in colour, with faintly barred underparts and buff fringes to greater coverts.
Sound:Alarm call very harsh, nasal and noisy. Dry and not as deep or resonant as crows. Song varied. During breeding season a varied subdued song is heard from both sexes. Territorial call before breeding starts is simple, loud and resonant. Consisting of pleasant sounding single or double syllables, with well defined pauses and peculiar harmonics.

Forked and fairly long tail. Clearly bigger than Storm Petrel, with more slender appearance and longer wings. Generally not as black, and shows brownish tone to plumage. The white rump patch is oval, has a weak grey center stripe, and does not reach as far down on the sides as in Storm Petrel. Light grey upper greater coverts form a wing-band. Underside of wings all dark. Flight pattern variable, with frequent changes in direction and speed. Sometimes glides like a shearwater but at other times shows surprisingly deep wing-beats. Does not patter surface, but will rest on water. Visits breeding ground only at night, and is usually only seen after storms.
Sound:Only calls at breeding ground. A series of accentuated cooing, interrupted by a squeaky "inbreath" and a loud, absurd, fanfare-like "kaaa-ka-ka-kaaa-ka".
