Spotted Nutcracker (Nucifraga caryocatactes)
Leach's Storm Petrel (Hydrobates leucorhous)
Largely unmistakable. Chocolate brown body with small white dots. Wings and crown dark brown without spots. Tail dark with broad white edges/corners. Vent shiny white. Recognizable at long distance when in flight, by its peculiar flight pattern and profile. Fluttering, "inefficient" wing beats, short tail, long bill and often a throat bulging with seeds.
Sound:Fairly silent. Warning call a characteristic dry and rasping "karrr karrr karr" in even pitch. Song a quiet improvisation of whistling and clappering sounds, interspersed with mimicry of other birds.

CCForked 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".
