We also saw many Great Frigatebirds at the lighthouse. They are able to soar effortlessly on their long, angular wings. The Hawaiian name for them is ‘Iwa which means “thief”. The name comes from their habit of chasing Boobies, Shearwaters, and Terns and forcing them to drop their food. The Frigatebird is usually able to catch the dropped food in midair. This is a female; she is identified by her black plumage with white throat and chest (the male is all black).
