The name "frigatebird" was inspired by fast, maneuverable frigates, or man-o'-war ships, used by pirates centuries ago. * The breeding period of the Magnificent Frigatebird is incredibly long. Males and females incubate the eggs for approx. 56 days, and once hatched, chicks don't leave the nest until they are around 167 days old. Females continue to feed youths until they are one year old, even after they have left the nest. *Young frigatebirds have been observed practicing thievery, where youths holding sticks in their mouths chase each other. When one drops the stick, the other dives below to retrieve it.
