The
oceanographic and coastal features of the British Isles provide a wealth of
ideal habitats for breeding seabirds and it is no surprise that the British and
Irish seabird populations are of international importance, both in sheer numbers
and in species diversity. Indeed, for some species British waters are host to
the greater part of the world’s population.
This book presents the most up-to-date information available on these seabird
populations, their numbers and distribution, and their changing fortunes in
recent years. The Operation Seafarer survey, carried out in 1969–70, provided
a baseline for future work that led to the establishment of the Seabird Colony
Register by the Seabird Group and the Nature Conservancy Council. The results
and analysis of their counts during 1985–87 form the basis for this book.
Improved census methodology and a new computerised database has set ·the
standards for seabird monitoring in future decades.
In Part 1 the general biology and population trends of British seabirds are
described to set the scene for Part 2, in which the results and analysis for
each of the 24 breeding species are given in detail. Full descriptions of the
counting methods and the estimating factors used provide guidelines for future
surveys not only in Britain, but wherever seabirds are of interest and
importance.
No-one with an interest in seabirds or conservation can afford to be without
this authoritative book, nor but be grateful to the small army of professionals
and amateurs who have so ably explored our coastal habitats.
