Following the publication of Andrew Self’s Michael West book The Birds of London, our Rarities Committee has made some changes to our Checklist. The Checklist now includes Snow Goose, Black Grouse and Black Guillemot, ASSISTANT TREASURER but no longer includes American Wigeon. Andrew’s paper in this report explains the Robin Blades reasons for these changes (see page 203). We have also decided to separate records World List Abbreviation: Lond. Bird Rep. formerly reported as Walton Reservoirs into two sites: Walton Res (Chelsea & Lambeth) © London Natural History Society 2016 and Walton Res (Knight & Beesborough). This follows changes to the Chelsea and Lambeth sections of these reservoirs. Designed by Nigel Partridge As space permits this time, we have included indexes of common and scientific names Printed by Swallowtail Print Limited, Norwich, Norfolk at the back of the journal (see page 250). Notes for Contributors are on page 255. We are sad to learn of the death of Gay Carr, who valiantly proof-read one section of ISBN 0 901009 42 3 Birds of the London Area in LBR 2012 while undergoing treatment for cancer. ISSN 0141 4348 It would be a great help in producing this report, if people would send us records as Published by soon as they can. In particular, we would like all records to be with our Recorders as the London Natural History Society – May 2016 soon as possible after the end of the year to which they refer. We will not usually be www.lnhs.org.uk able to be include in the LBR, records received after March 31st in the year following. Records of birds which are rare in London will not be published without our Rarities LONDON BIRD CLUB Committee receiving full details (notes/description or photo). Our Checklist on pages The London Bird Club is the section of the London Natural History Society 239-247 gives details of which species this applies to, and what details are needed, using for those with a particular interest in birds. the keys D, N or BBRC. http://www.lnhs.org.uk/ornithology1.htm The LNHS uses three different kinds of recording area: a circle for its outer boundary, twitter.com/londonbirdclub an Inner London rectangle, and the Watsonian vice-counties. There is sometimes confusion over the exact location of these, so the LNHS has commissioned GiGL to CHAIR publish them on their website. You can now see all of these on the iGiGL map at: Gehan de Silva Wijeyeratne http://www.gigl.org.uk/online, to check exactly which area your record is in. COMMITTEE SECRETARY The Editorial Board, which took over the production of LBR in September 2010, has Angela Linnell managed to catch up with the backlog of reports now, but much of this work falls on 6 LONDON BIRD REPORT NO. 79 7 just a few people. We urgently need more people to help. In particular, we are looking RARITIES COMMITTEE AND RECORDERS for a new Editor of the Birds of the London Area section and for an Editor of the ——— Remaining Sections (pages 1-27 and 239-248 of this report). Please contact me if you could help with this. There are many uses of the word London in this report. Usually this refers to the LNHS RARITIES COMMITTEE recording area (see page 8 for details). But when we comment on Breeding Bird Survey Chairman: Bob Watts data in London, we are giving figures for the smaller area used by the BTO for their Members: John Archer, Richard Bonser,
