Economic Importance and Threats
Threats:  Natural threats
(This species is highly threatened because its population is small, confined to one small area of land, and potentially at risk from an invasive species of ant. The restriction of its entire breeding population to a single island elevates the potential impact of natural disaster or disease. Numbers of breeding frigatebirds on Chistmas Island have declined in some areas, although the overall population is thought to be stable, habitat destruction, disturbance and human predation of birds and eggs have been the main causes of decline. The species is also, and perhaps most seriously, threatened by an invasive species, the Yellow Crazy Ant (Anoplolepis gracilipes), which is spreading across the island, this insect is likely to prey directly on nestlings and to alter the island's ecology by farming scale insects that damage trees and the dominant life-form on the island.)

Habitat:  Pelagic, Coastal
Trophic Level:  Consumer
Prey:  Fish and squids.
IUCN Status:  Critically Endangered
