Breeding begins in September, occuring in colonies where it nests in long burrows excavated in soft soil under grass tussocks (del Hoyo et al. 1992). Foraging during the chick-rearing period at the Kerguelen Islands involves regular alternation between short trips in the vicinity of the island and long trips to Antarctic waters. Short trips enable an increase of chick-feeding frequency at the expense of energy reserves built up during long trips. Diet comprises of crustaceans (especially krill), fish, squids and some insects (del Hoyo et al. 1992, Cherel et al. 2002). The highest recorded blue petrel burrow in surveys by Dilley et al., (2019) was found at an elevation of 200m.

The Blue Petrel is found throughout southern Oceans. Breeding sites include the Crozet Islands and Kerguelen Island (French Southern Territories), Marion Island and Prince Edward Island (South Africa), Macquarie Island (Australia) and South Georgia (Georgias del Sur). Adults are perhaps mainly sedentary, though young birds are more dispersive (del Hoyo et al. 1992).

Conservation Actions Underway
Cats were eradicated on Marion Island in 1991, which led to an increase in Blue Petrel breeding success (Cooper et al. 1995). European Rabbits were eradicated on Ile Verte in 1992, which was followed by an increase in Blue Petrel population within six years of the eradication Brodier et al. 2011).

Conservation Actions Proposed
Research into the extent of nest predation by introduced house mice Mus musculus on petrel breeding success (Cerfonteyn and Ryan, 2016) .
