Christmas Frigatebird. It belongs to a family of five birds, the Fregatidae, which have the largest wingspan to body weight ratio of any bird. This bird has the ability to stay airborne for more than a week at a time allowing them to have a large foraging range. It spends a large proportion of time at sea, plucking squid and fish from the surface of the water. They also employ a method of feeding called kleptoparasitism; where they steal other birds’ food by forcing them to regurgitate. Its breeding habitat is affected by invasive yellow crazy ant, which is a key threat to many species on the island. They are also threatened by hunting, getting trapped in fishing gear, habitat destruction for phosphate mining, and the ecological fallout from the phosphate dust. Much of the breeding colony now lies within the Christmas Island National Park, but almost 10% of the population nests outside this area which does not have any formal protection. With such small numbers surviving, every individual counts and conservation measures must protect the entire population. Elevation: 0 m. Date added to IBC: April 5, 2019.
