The Sooty Shearwater — Puffinus Griseus (J. F. Gmelin)
This species visits us yearly but is much scarcer than the Great Shearwater.
Its only known nesting haunts are in Chatham Islands and others near New Zealand, but the birds which visit us probably nest in the South Atlantic.
The whole of the plumage is brown, rather greyer below and more mottled. Legs blackish outside, lilac grey within. Length 18 in.; wing 12 in.
