The cuckoos are the most variable birds in social behavior and parental care: a few cuckoos are among the most social of all birds and rear their young in a common nest; most cuckoos are caring parents that rear their own young with some females laying a few eggs in the nests of others; while many cuckoo species are brood parasites who leave their eggs in the nests of other birds to rear, with their young maturing to kill their foster nestmates. In The Cuckoos, Robert B. Payne presents a new evolutionary history of the family based on molecular genetics, and uses the family tree to explore the origins and diversity of their behaviour. He traces details of the cuckoos' biology to their original sources, includes descriptions of previously unpublished field observations, and reveals new comparisons of songs showing previously overlooked cuckoo species. Lavishly illustrated with specially commissioned colour plates and numerous maps, halftones, and line drawings, The Cuckoos provides the most comprehensive and up-to-date account of this family yet available.
A gifted biologist's careful and beguiling study of why cuckoos have got away with tricking other birds into hatching and raising their young for thousands of years. The familiar call of the common cuckoo, “cuck-oo,” has been a harbinger of spring ever since our ancestors walked out of Africa many thousands of years ago. However, for naturalist and scientist Nick Davies, the call is an invitation to solve an enduring puzzle: how does the cuckoo get away with laying its eggs in the nests of other birds and tricking them into raising young cuckoos rather than their own offspring? Early observers who noticed a little warbler feeding a monstrously large cuckoo chick concluded the cuckoo's lack of parental care was the result of faulty design by the Creator, and that the hosts chose to help the poor cuckoo. These quaint views of bad design and benevolence were banished after Charles Darwin proposed that the cuckoo tricks the hosts in an evolutionary battle, where hosts evolve better defenses against cuckoos and cuckoos, in turn, evolve better trickery to outwit the hosts. For the last three decades, Davies has employed observation and field experiments to unravel the details of this evolutionary “arms race” between cuckoos and their hosts. Like a detective, Davies and his colleagues studied adult cuckoo behavior, cuckoo egg markings, and cuckoo chick begging calls to discover exactly how cuckoos trick their hosts. For birding and evolution aficionados, The Cuckoo is a lyrical and scientifically satisfying exploration of one of nature's most astonishing and beautiful adaptations.
Many species of cuckoo lay their eggs in the nests of other birds. After the young cuckoo hatches, it may eject the other babies from the nest so it can thrive. Readers learn these and other amazing facts about the life cycle of the cuckoo through engaging and information text. Colorful photographs engage readers in the easy-to-read explanations. Fact boxes add even more weird information about the cuckoo, and graphic organizers enhance readers’ understanding of science content.
With nearly six hundred identified species of birds—and an average of five "new" species discovered annually—Belize is becoming a birding hotspot for amateur and professional birders from around the globe. Thousands of birders visit the country each year to enjoy Belize's amazing abundance and variety of both temperate and tropical birds in natural habitats that remain largely unspoiled. But until now, despite the growing need for an authoritative identification guide, birders have had to rely on regional field guides that offer only limited information on Belizean birds. Birds of Belize provides the first complete guide to the identification of all currently known species—574 in all. The birds are grouped by families, with an introduction to each family that highlights its uniquely identifying characteristics and behaviors. The species accounts include all the details necessary for field identification: scientific and common names, size, plumage features, thorough voice descriptions, habitat, distribution, and status in Belize. Full color, expertly drawn illustrations by noted bird artist Dana Gardner present male and female, juvenile and adult, and basic and alternate plumages to aid visual identification throughout the year, while 234 range maps show the birds' distribution and seasonality in Belize. A comprehensive bibliography completes the volume.
