Size/Age/Growth

About 16 inches long, with a wingspan of 35 to 40 inches. Adults weigh about 9.8 ounces .

Habitat

Vegetation: freshwater marshes, pelagic waters • Zoogeographic Region: o • Foraging Strata: Water • Center of Abundance: Lower tropical: lowlands, lower than 500 m.; tropics. • Sensitivity to Disturbancet: High

Typically found at an altitude of 0 to 864 meters (0 to 2,835 feet).[1]

Biome: Terrestrial ; Marine

Ecology: It nests (starting in December) colonially in cliff burrows, often within montane forest at 1,500-2,000 m , but up to 2,300 m in the Dominican Republic7. Nesting birds commute large distances from breeding to foraging sites3. It is primarily nocturnal and crepuscular, feeding on fish, invertebrate swarms , fauna associated with Sargassum seaweed reefs3, and squid5. It is attracted to localised upwellings , where the mixing of surface and deep oceanic waters produces nutrient-rich areas3.[2]
