Here in Alaska, and in most of the United States, there is only one species of Kingfisher. The Belted Kingfisher is fairly large and impressive though not particularly colorful. Near the Mexican Border and to points south, there are two other species of Kingfisher, the small, Green Kingfisher, and the massive Ringed Kingfisher. Still further south there are 3 more kingfishers, American Pygmy Kingfisher, Green and Rufous Kingfisher, and Amazon Kingfisher. All of them look similar to Green Kingfishers. I have seen them all except for the Green and Rufous Kingfisher.
During my recent trip to South Africa, I was impressed by the 6 species of kingsfisher I saw there. Woodland, Brown-headed, Mangrove, Pied, Giant, and the brilliant Malachite Kingsfisher. There are many other species in Africa, and most are very colorful.
