Among the most easily identified of a cryptic family, the attractive Sand-colored Nighthawk often hangs out on sandbars in rivers during the day, making it among the more cooperative members of its mostly nocturnal family as well. (Photo by Bill Byers.)
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.)
