Birds of Conservation Concern 3: the population status of birds in the United Kingdom, Channel Islands and Isle of Man.

Abstract

This is the fourth major review of the status of birds occurring in the UK, Channel Islands and Isle of Man. We present Red, Amber and Green lists of conservation concern based on assessments using objective listing criteria and using the most recent data. The listing criteria assess global conservation status, historical population decline, recent population decline (numbers and geographical range), European conservation status, rarity, localised distribution, and international importance of populations. Some changes have been made to the criteria since the last assessment, and the effect of these changes is discussed. Of 246 species assessed, 52 (21.1%) have been placed on the Red list, 126 (51.2%) on the Amber list and 68 (27.6%) on the Green list. Eighteen species have moved onto the Red list since the last assessment in 2002, and six have moved from Red to Amber.
