The Greater Frigatebird is one of Norfolk Island's most distinctive inhabitants, well known for bright red throat pouches that males bring out for mating season (but which remain essentially invisible the rest of the year). Displays like this aren't too common; with young birds dependant on parents for more than a year, the species will only mate every 1-2 years. Have you made the trip to Norfolk Island?
