Looking like a cross between a big tern and a skimmer, Large-billed Tern also has the beautiful tricolor upperwing pattern that reminds us of Sabine’s Gull and Swallow-tailed Gull. This species is found mostly in lowland rivers of South America, but one wandered to Hackensack, New Jersey in 1988! (Photo by Bill Byers.)
Also lovers of riparian environments, Hoatzins are birds we never tire of studying for long periods. Their odd calls, wide-eyed interest in human activities, and artless clambering around branches as they search for fresh leaves to eat make them almost monkeylike. (Photo by Charlotte Byers.)
Slightly less cuddly, but often interesting to observe in action, White Caimans are one of four caiman species that prowl the Tambopata. (Photo by Bill Byers.)
