The nightjars and their allies are amongst the most difficult of all birds to identify. Being strictly nocturnal and cryptically patterned in shades of brown, it is often necessary to rely on size, shape, habitat and voice to safely identify a species.The nightjars are by far the largest family in the order and are spread throughout the world. Some species have developed spectacular tails and wing adornments, but the majority are fairly uniform in appearance. They inhabit both forests and deserts and are ground-nesting. Many species are migratory. The forest-dwelling frogmouths of Asia and Australasia and the potoos of Latin America, adopt a less aeiral feeding strategy and nest on open branches or in tree crevices. The unique oilbird of South American nests colonially in caves, and the owlet-nighjars almost exclusively inhabit Australasia.This book fully covers this popular group of birds. The text has been thoroughly researched, both in the museum and in the field, and the plates depict feather-by-feather detail, allowing identification of all species, providing adequate views are obtained.As voice is so important in nightjar identification, an accompanying CD (priced separately) with the voices of many species will be issued simultaneously."
