There are few birds easier to recognize than male magnificent frigatebirds. They have a giant red throat pouch which makes for a bright, stunning display when fully inflated. It's almost comical to see them puff up. Of course, the brighter the pouch, the more attractive they appear to females.
Though magnificent frigatebirds are migratory birds found across the Atlantic Ocean and Central and South America, the colonies that inhabit the Galapagos are thought to be genetically distinct, not having bred with mainland counterparts for several hundred thousand years.
