When, in 1984, Benny Génsbol first published the Collins Guide to the Birds of Prey of Britain and Europe, North Africa and the Middle East it received a warm welcome. This chunky, field-guide-sized book was reissued several times but then in 2004 it was completely revised and issued in Danish - and now we have an English version.
An introduction of 35 pages explains the characteristics of birds of prey, their breeding biology and migration, and summarises the challenges they face from habitat change and pollution. One change since 1984 is the fact that in many areas most birds of prey are currently increasing - although a few are more threatened than they were 24 years ago.
Each species is given its own account, including a decent-sized distribution map and summary population trends across its range. The maps have been updated and although the book has been revised on a regular basis it is interesting to compare the changes since 1984. Goshawk was restricted to just a few tiny areas around the Peak District and southern Scotland, and now it covers the whole of Great Britain and has a tiny population in Northern Ireland. However the maps are not perfect. Hobby has greatly increased in Great Britain in recent years but the map shows it as being absent. Montagu's Harrier and Honey Buzzard are also not shown as breeding here yet the text refers to 9-16 pairs and 70 pairs of each nesting. Similarly Egyptian Vulture and Black Vulture are incorrectly shown as breeding in Cyprus. The distribution maps include North Africa although the text ignores population data for these areas. Breeding distribution is indicated by four shades of green (a test for your eyesight!) and non-breeding winter ranges are indicated by blue. I was also a bit surprised to see Spanish Imperial Eagle included on same map as Imperial Eagle.
For me one of the book's best selling points is its up-to-date information on population trends with statistics for each species across Europe (but not North Africa). Where migration routes are known these are explained, together with recent data on counts and the best time to be in position. Another great feature is the wide range of photographs - very few of which are repeated from the original book. These, together with a 165-page section on identification, make this an excellent field guide for raptor enthusiasts. The colour drawings of raptors in flight are a vast improvement on those in the original book, and are well laid out for use in the field. The texts that accompany these are clear and concise.
