PORCUPINE A Society to promote interest in the ecology and distribution of marine fauna

and flora in the N.E. Atlantic. The name porcupine is derived from the surveying vessel of that name

which is immortalised in the reports of the Lightning and Porcupine expeditions and in the Porcupine Bank west of Ireland.

The chief aims of porcupine are: 1. To promote interest in aspects of marine biology involved in the recording

and distribution of marine organisms. 2. To be a forum for discussion of progress and problems at all levels

especially on a personal basis at meetings. At the moment it is envisaged that meetings will occur three times a year

and be held at various venues in Scotland, N. England and Ireland, to facilitate those without easy access to London. The meetings will normally last two days and take the form of discussion or field work centered on a particular theme.

3. To publish a Newsletter usually soon after each meeting. The substance of the Newsletter will be a resume of the meeting's progress.

Additional articles on a wide range of subjects are welcome.

REVIEWS Bird Observatories in Britain and Ireland. Edited by Roger Durman. 292 pp. ?5.00 T. & A.

D. Poyser. Berkhamsted. Robert Spencer, deputy director of the British Trust for Ornithology, has written

the introduction to this interesting and informative book, which tells the story of the Bird

Observatories since the first one, Skokholm, was set up in 1933. There are at present four

teen* of them, although in aU twenty-five have operated at one time or another. Their main

function is to provide information about the migration of birds by visual observation and by

trapping and ringing. They have contributed a great deal of knowledge to the study of birds as well as providing a training ground for young ornithologists.

A chapter on each of the present observatories has been written by one of its

members, giving information about the history and geography, bird movements and Tecords, and domestic arrangements for each. The one on Copeland, County Down, has been

written by Mr Neville McKee, a founder member and currently Boat Officer and Records

Secretary. The chapter on Cape Clear Island, County Cork, has been written by Mr Tim

Sharrock, also a founder member and organiser of the BTO/IWC atlas project. Other Irish

observatories were at Saltees, Tory Island and Malin Head, but these have ceased to

function for some years. Also included are some black and white photographs illustrating the buildings and traps of some of the observatories and some excellent maps and tables.

This book will be of great interest to existing observatory workers and should

attract many more to take up observatory life. Copies can be purchased from Copeland Bird Observatory c/o Mr Neville McKee, 19 Deerpark Gardens, Belfast 14, Telephone No.
