The Great Shearwater — Puffinus Gravis, O’Reilly
This species is a fairly regular summer visitor to the waters round our coasts, but it does not often approach the land.
Nothing is known of its breeding haunts, which are probably in the Antarctic seas.
The upper parts are ash brown, mottled with white on the upper tail coverts. Under parts white, sometimes brownish on the belly. Legs pinkish. Length 19 in.; wing 12·7 in.
