Petrels night and day. By Magnus Robb and illustrated by Killian Mullarney. 2008, The Sound Approach.
This is a comprehensive exploration of the petrels of Europe and North Africa. You can listen to previously unpublished digital stereo recordings of 23 species of petrels nesting on islets, islands and coasts of the North Atlantic and the Mediterranean. You will learn how to separate them by ear, with the help of clearly annotated sonagrams. You can read the author's tales of making the recordings, and learn where to go to experience the birds.
There is a series of full-colour plates and photographs for birdwatchers and especially seawatchers. Many if the photographs were taken at the same time as the recordings. Most importantly, read how the latest research is leading to the recognition of new - European - species, some of which are exceedingly rare. Written and illustrated by enthusiasts so be warned: this book could be the start of a serious obsession.
300 pages, 20,5 x 28,8 cm, Hardback, Illustrations: 18 colour plates + numerous colour photos. Includes two CDs with 127 recordings. ISBN-13: 9789081093323

Birds of the Atlantic Islands – Canary Islands, Madeira, Azores & Cape Verde. By Tony Clarke and illustrated by Chris Orgill and Tony Disley. 2006, Helm Field Guides.
This is the first comprehensive field guide dealing exclusively with the birds of this spetacular region. It covers all resident, migrant and vagrant species found in Macaronesia which comprises the Canary Islands, Madeira, Azores and Cape Verde. Over 450 species are illustrated with full details of all the plumage variations and for all major subspecies which are likely to be found anywhere in the area. Concise text offers descriptions of identification, status, range, habits and song. This authoritative book will not only be an indispensable guide to the visiting birder, but also a vital tool for those engaged in work to conserve and study the avifauna of this region. The Atlantic Islands shelter a remarkable diversity of birds, many seriously endangered with small and vulnerable ranges.
368 pages, 23,4 x 15,6 cm, paperback. Illustrations: 56 colour plates.

Bird related articles about the archipelago
There is a huge bibliography on Selvagens. The first record of a known scientist on Selvagem Grand was Captain Cook on "Endurance" with Banks on board. It was doubtful if they ever landed and the real purpose of the landfall was for navigational purposes.
   Only Mougin must have published 30-40 papers on Selvagens birds as well as Roux, and Frank Zino have been involved in many of these publications, which see below.
