Πελαγικό(ά); εύρος βάθους 0 - 66 m (Αναφ. 58635), usually 1 - 14 m (Αναφ. 58635). Tropical; 21°C - 31°C (Αναφ. 96995)

Length at first maturity / Μέγεθος / Weight / Age
Γεννητική Ωρίμανση: Lm ?  range ? - ? cm Max length : 46.0 cm TL αρσενικό/απροσδιόριστο; (Αναφ. 8812); μεγ. δημοσιευμένο βάρος: 570.00 g (Αναφ. 356)
Culmen: 4.04 cm; tarsus: 5.13 cm; wing: 31.0 cm.
Total Length: 41 to 46 cm; Wingspan: 97 to 104 cm (Ref. 8812). Occupies ridges and burrows. Form small breeding colonies on headlands and the tops of coastal cliffs; found in groups of burrows rather than spread out (Ref. 89480). Colonial breeder on oceanic islands. Typically gregarious at sea; does not trail ships (Ref. 91362). Found along seashores (Ref. 83946) and the continental shelf. Exhibits pursuit-plunging and surface-diving (Ref. 81748). Feeding mode: contact dipping (birds flew close to the surface to catch their prey); feeding on the surface (birds catch their prey from a sitting position or surface dive); air dipping (observed infrequently; birds catch the flying fish) (Ref. 96995).
Life cycle and mating behavior

Breeding season is dependent on the area: from April to November in northern subtropical Pacific localities; from October to May in southern subtropical Pacific localities; breeding cycle in tropical Pacific localities extends the eight-month breeding season of those in the subtropical Pacific.
