Hi, I'm a returning Birdwatcher who having dusted down his old Mitchel Beasley Pocket Guide, treated myself to Rob Hume's Birds of Britain & Europe RSPB/Dorling Kindersley ISBN: 0751312347. I've found the photograph's stunning and the descriptive information excellent. I haven't seen many references to it on this thread - recommendations seem to be for the Collins guide - am I missing something by not having the Collin's Guide, and if so can someone give me the ISBN?
