One of The Birdbooker Report's Best Bird Books of 2011 "Incredible... A definitive monograph on the birds concerned: the sections on specific taxa include colour photos (many showing species that have hardly ever been photographed before) as well as huge amounts of new data on ranges, voice and behaviour. I don't think there can be much doubt that this is the new standard work on these birds."--Darren Naish, Scientific American "A must have for those with an interest in Neotropical birds or collectors of family monographs!"--Ian Paulsen, Birdbooker Report "Definitive... This book will have you booking your next trip to the Neotropics! ... It's a treasure trove of information and beauty from the cover to the last page."--Eva Matthews, Flying Mullet blog "An identification tour de force."--British Trust for Ornithology "Mr. Kirwan and Mr.Green bring you vast information about their habitats, location maps. Also identifications, descriptions, distributions and status. Let's not forget the wonderful color illustrations and terrific plates... A 'must have'."--H.J. Ruiz, Avian 101 blog "Invaluable to anyone studying this group of birds, as well as birders looking to learn more about these colorful gems... A fantastic book that is worth adding to your library if you are making the trek to Central/South America, or you are as fascinated with these birds as I am."--Drew Weber, Nemesis Bird blog "Cotingas and Manakins is a brilliant piece of work and well worth having in your library."--Frank Lambert, Birder's Library "Cotingas and Manakins is a massive, erudite, and gorgeous compilation of all extant knowledge about cotingas and manakins, undoubtedly the two most extravagant and fascinating bird families of the neotropics."--Derek Kverno, Birding Brazil "[T]his volume will stand as the authoritative guide to this remarkable group of birds for years to come. It will appeal to tropical ornithologists and conservation biologists, as well as to globetrotting birders, who, after poring over the text and savoring the illustrations, will begin to daydream about their next trip to the New World tropics."--Mark Riegner, Quarterly Review of Biology "What a treasure! ... Failure to treat these amazing birds with the care they deserve might have turned me against the book. As it is, I was consistently delighted; the book should be a key reference for anyone interested in these two families... This book will be a cherished resource... I highly recommend it to anyone with a strong interest in Neotropical birds, and cannot imagine why anyone with more specialized interest in the manakins and cotingas could possibly fail to own it."--David B. Mcdonald, Wilson Journal of Ornithology
