1176. Eastern Dusky Shearwater.
PUFFINUS ASSIMILIS.
Puffinus assimilis, Gould, P.Z.S. 1837, p. 156 ; id. B. of Austral, vii. pl. 59 ; Dresser, ix. p. 407 ; Salvin, Cat. B. Br. Mus. xxv. p. 384 ; Ridgway, p. 61 ; Saunders, p. 743 ; P. nugax, Solander, M.S. Bp. Consp, ii. p. 205 (1856) ; P. bailloni, Bp. Compt. Rend. xiii. p. 769 (1856).
Ad. (Porto Santo). Differs from P. obscurus in having the upper parts rather bluer in tinge, the white extending rather more round the eye and on the lores ; under wing-coverts, axillaries, and under tail-coverts pure white ; outer portion of inner web of primaries white except at the tip ; bill dark horn-colour ; tarsi and toes greenish yellow ; webs yellowish orange ; iris dark brown. Culmen 1.2, wing 7.1, tail 2.85, tarsus 1.42 inch.
Hab. The Australian and New Zealand seas ; the Atlantic north to the Canaries and Madeira ; has occurred on the coasts of Great Britain at least twice.
In habits it resembles P. obscurus. Mr. Grant says that it is a very silent bird, but Mr. Boyd Alexander states that when on the wing it continually utters a weird cry, karki-karrou, karki-karrou, karki-karrou. It breeds in holes, under boulders, and in clefts of rocks, depositing a single white egg, which measures about 1.70 by 1.32.
I have carefully compared specimens from the North Atlantic with those from Australia, and fail to find any difference, therein agreeing with Mr. Salvin.
