Chinese Grey Shrike © James Eaton/Birdtour Asia

Norbert Lefranc and Tim Worfolk are preparing a revised edition of 'Shrikes: a Guide to the Shrikes of the World' for Bloomsbury Publishing.

The book will include photos and the authors are seeking images of as many species, subspecies and recognisable plumages as possible. Photos should be uncropped, preferably in RAW or TIFF format, however for rarely photographed species a high quality JPEG may be acceptable.

All published photos will be individually credited. Unfortunately the budget is insufficient to allow payment, but contributing photographers will receive a copy of the book. Please contact Tim Worfolk timworfolk@blueyonder.co.uk if you think you can help.
