[edit] Taxonomy

[edit] Status of Spectacled Petrel conspicillata

Recently, the SACC (2008) passed a proposal to separate conspicillata as a full species, citing vocal differences noted by Ryan (1998). However, it is treated as a subspecies of aequinoctialis by most authorities (Clements 6th edition, 2007; Howard & Moore, 2003; Sibley & Monroe, 1996), and the Opus follows this consensus.

[edit] Habitat

Open sea.

[edit] Behaviour

The diet includes krill.
