Birdswatching Tour – Vultures

New World vultures are familiar carrion feeders, with bare, unfeathered skin on the head and neck. Most often seen in soaring flight. Black Vulture locates food sources entirely by sight, but all Cathartes have welldeveloped sense of smell and can detect carrion that is hidden in vegetation. The largest and most impressive vultures, King Vulture and Andean Condor, are on plate 28. The flight profile of Zone-tailed Hawk closely mimics Cathartes vultures; see account on plate 40.1

Birding Tours .Hrons and Spoonbill

Herons and egrets are long-necked, long-legged birds with long, daggerlike bills; fly with neck retracted and
long tarsi protruding beyond tail. Most forage by wading slowly in water, capturing animal prey with sudden
lunges of neck and bill. Some species nest in colonies that may contain several species of herons and ibis. In many species soft parts become more intensely colored for a short period in breeding season, at which time some also acquire long plumes on neck or lower back. The spoonbill is superficially similar but is related to ibis; note its peculiar bill shape.
