Great FrigatebirdFregata minorA large black seabird that holds its wings in a distinctive crook. The long, forked tail may appear pointed when folded. Males are all black with a red throat pouch. Females have a white breast. Immatures have a white head and breast. All-dark plumage of male and lack of a pale “armpit” in female and immature separate this species from Lesser and Christmas Island Frigatebirds. Separation from Magnificent Frigatebird can be difficult; note pale wing panel in males and indistinct pale throat in females (Magnificent females have a clean all-dark head). Nests in trees and bushes on tropical islands. Often seen flying along the shoreline, sometimes very high, and sometimes inland. Chases other seabirds to steal their prey.Fregatidae bird family

Magnificent FrigatebirdFregata magnificensMassive seabird of warm tropical oceans and coastlines. Overall black with extremely long, deeply forked tail and angular wings. Male completely black with inflatable red pouch on throat (not seen away from breeding colonies) and bluish eyering. In good light, black coloration can show purplish sheen. Adult female has white chest and golden bar on shoulder. Young birds have white head and breast. Often soars for long periods and flies with slow wingbeats. Steals food from other seabirds. Surprisingly acrobatic during aerial chases despite its large size. Limited range overlap with Great Frigatebird (mainly offshore western Mexico and in the Galapagos); identification is complicated by age and sex variation. Adult males are extremely similar; females and immatures best identified by exact pattern of white on head and breast, bill color, and eyering color.
