Massive 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). Adult female has white chest and golden bar on shoulder. Young birds have white head and breast. Only frigatebird species typically found in North America; unlikely to be confused with any other species due to size and shape. Often soars for long periods and flies with slow wingbeats. Steals food from other seabirds. Surprisingly acrobatic during aerial chases despite its large size.
