Environment: milieu / climate zone / depth range / distribution range
Ecology
Pelagic; depth range 0 - 10 m (Ref. 59262). Subtropical; 22°C - ? (Ref. 84934); 23°N - 24°S, 39°E - 6°W

Length at first maturity / Size / Weight / Age
Maturity: Lm ? range ? - ? cm Max length : 77.0 cm TL male/unsexed; (Ref. 8812); max. published weight: 1.5 kg (Ref. 356)
Culmen: 8.47 cm; tarsus: 3.5 cm; wing: 40.7 cm.
Total Length: 66 to 77 cm; Wingspan: 91 to 101 cm (Ref. 8812). Wingspan: 152 cm. The smallest booby (Ref. 91362). Causes of decrease in population is human exploitation, habitat destruction especially in the Western Indian Ocean, predation by rats, and tourism disturbance (84934). Found <200 m offshore, over deep waters (Ref. 356). Colonial breeder in trees on marine islands. Gregarious; freely approaches ships, undertaking long foraging trips (Ref. 91362). Exhibits plunge diving (Ref. 356). Maturity at past 2 to 3 years (Ref. 91362).
