Nidification. This Petrel has been found breeding in Kerguelen Island during March, laying one egg in a crevice in a rock. An egg is described by Mathews as "dull white, minutely and sparingly dotted all over with small pink dots" and measuring 37 x 27 mm. During the South Orkney Expedition a bird was caught in Laurie Island on December 5th on its nest, a hole in a rock, fifteen feet above the sea. The egg from this nest measured 36.0 x 25.5 mm.

Habits. Much the same as those of the preceding bird. The note is said to be a shrill piping uttered every few seconds by the birds on the wing.
