Birds of South Asia: The Ripley Guide


Birds of South Asia: The Ripley Guide by Pamela C. Rasmussen and John C. Anderton is a two-volume ornithological handbook, covering the birds of South Asia, published in 2005 by the Smithsonian Institution and Lynx Edicions. The geographical scope of the book covers India, Bangladesh, Pakistan, Sri Lanka, Nepal, Bhutan, Maldives, the Chagos archipelago and Afghanistan. In total, 1508 species are covered. Two notable aspects of Birds of South Asia are its distribution evidence-base — the book's authors based their distributional information almost completely on museum specimens — and its taxonomic approach, involving a large number of species-level splits.

The books

Volume 1 is a field guide. A nine-page introduction is followed by 180 colour plates, each with an accompanying text page giving brief identification notes, and, for most species, range maps. In addition to the 69 plates by Anderton, eleven other artists contributed, including Ian Lewington and Bill Zetterström. Volume 2: Attributes and Status contains more detailed supporting texts for every species. Twelve other authors are listed as having contributed to this volume, including Per Alström, Nigel Collar and Craig Robson. This volume opens with an appreciation, written by Bruce Beehler, of S. Dillon Ripley, who initiated the work which led to the book, and after whom it is named. This is followed by a 24-page introduction. The bulk of the book, from pages 41 to 601, consists of individual species accounts; each of these includes sections on identification, occurrence, habits and voice. There are ten appendices, including a hypothetical list, a list of rejected species, a summary of taxonomic changes, a glossary, a gazetteer, and a list of institutions holding major collections of South Asian bird specimens.
The book's covers are illustrated by montages of South Asian birds, painted by Anderton. Volume 1 features crimson-backed flameback, stork-billed kingfisher, Indian eagle-owl, black-and-orange flycatcher and Himalayan quail on its front cover. Volume 2 features six laughingthrush species: variegated, Bhutan, grey-sided, blue-winged, black-chinned and Assam. The back covers of both volumes feature a painting of Serendib and Nicobar scops-owls.

Taxonomic changes

In preparing the book, the authors undertook a major revision of the taxonomic status of bird forms found in the region; many allopatric forms previously regarded as conspecific are treated by Rasmussen and Anderton as full species. Many of these had previously been proposed elsewhere, but the book introduced a number of innovations of its own. The majority of these changes, and the overwhelming majority of the novel ones, are among the passerines. The following is a list of the groups of taxa which are considered conspecific in the sixth edition of the Clements Checklist, but split into two or more species in Rasmussen and Anderton's work.

Non-passerines

The taxonomic changes proposed increase the number of South Asian endemic bird species, and the numbers of restricted-range endemic bird species in several of South Asia's Endemic Bird Areas. Using the taxonomic arrangements in Birds of South Asia, the following species are additional South Asian endemics: Ceylon bay-owl, hill swallow, white-bellied and orange minivets, square-tailed black bulbul, Jerdon's leafbird, Indian blackbird, large blue flycatcher, common babbler and Indian and white-cheeked nuthatches; the following are additional Indian endemics: crested hawk-eagle, grey-fronted green-pigeon, Malabar barbet, Malabar woodshrike, flame-throated bulbul, Nilgiri thrush, white-bellied blue robin, Naga wren-babbler, Indian yellow tit, Nilgiri flowerpecker and Malabar white-headed starling; the following are new Sri Lankan endemics: Ceylon green-pigeon, Ceylon small barbet, crimson-backed flameback, Ceylon swallow, Ceylon woodshrike, black-capped bulbul, Ceylon scaly thrush and Ceylon crested drongo; and the following are additional endemics in the Andaman/Nicobar islands: Nicobar imperial-pigeon, Andaman barn-owl, Hume's hawk-owl, Andaman cuckooshrike, Andaman bulbul, Nicobar jungle-flycatcher, Andaman shama and Andaman flowerpecker.
