Apart from 51 additional species, major improvements compared to the French version are:
– supplementary information in the introduction,
– addition of BTO codes and wing tip data in the heading of each species account,
– measurements of all treated species in the ‘identification’ section,
– the addition of schematic figures of moult sequences,
– addition of distribution range notes for all species,
– addition of EURING age codes in ‘moult’ and ‘age’ sections,
– improved organisation of figures clarifying them and becoming more comprehensive,
– addition of sonograms for some species (i.e. warblers…),
– addition of various informative figures and comparative illustrations,
– addition of bibliographic references at the end of each species account,
– different index marks for non-passerines and passerines,
– addition of appendix with a sample of moult and wing formula cards,
– and minor corrections and general updates to species accounts.
“[…] This guide will become an essential reference in ringing labs and observatories. Non-ringers will also find it a great resource, to improve their understanding of techniques used to identify, age and sex birds in the hand, some which rarely appear in field guides. And even those familiar with moult will find the moult progression charts illuminating. Just keep your magnifying glass handy.”

He has collaborated with various laboratories and institutes (Laboratory of Ornithology in Minsk Institute of Zoology, Chizé Centre of Biological Studies (CNRS), Emirates Centre for Wildlife Propagation, Max Planck Institute for Ornithology, University of Antwerp, University of Tromsö). Passionate about bird ringing, he got his ringing licence in 1998, and then participated in ringing activities in many countries (France, Belarus, Poland, Latvia, Lithuania, Spain, Israel […] ).
Hervé Lelièvre, PhD, is an expert in fauna who has worked in various laboratories (Universities of Rennes and La Réunion, National Center for Scientific Research, National Museum of Natural History). Having considerable experience of writing reports and scientific articles in English, he conducted the translation of the book as rigorously as possible, to provide the reader with clear and comprehensive contents.
George Candelin has been a ringer for over 20 years and is currently employed as a Senior Research Assistant by RSPB and he has worked in ornithological research for BTO, RSPB and Oxford University. He has travelled extensively within Europe and been involved with ringing in Scotland, Wales, France, Spain, Gibraltar and Cyprus. He has also held a CRBPO ringing licence and has participated in the ACROLA project. His experience includes a diversity of species ranging from swans and waterfowl, to seabirds, waders, raptors, gulls, pigeons, owls, swifts, woodpeckers, cuckoos, bee-eaters and passerines.
