Birds of Conservation Concern

BoCC4_coverThe population status of birds in the UK is regularly assessed through a collaboration of the UK’s leading governmental and non-governmental conservation organisations. The most recent review was undertaken in 2015, this being the fifth since 1990. The review used a range of criteria to place a total of 246 regularly occurring species onto one of three lists: Red, Amber or Green. This categorisation provides an indication of the priority that should be given to each species when allocating resources for conservation action.

Red list species are those that are globally threatened, whose population or range has declined rapidly in recent years (i.e. by more than 50% in 25 years), or which have declined historically and not recovered. Amber list species are those whose population or range has declined moderately in recent years (by more than 25% but less than 50% in 25 years), those whose population has declined historically but recovered recently, rare species (<300 breeding pairs or <900 wintering individuals), those with internationally important populations in the UK, those with localised populations, and those with an unfavourable conservation status in Europe. Species that meet none of these criteria are Green-listed.

Of 244 species assessed in 2015, 67 (27%) were placed on the Red list, 97 (40%) on the Amber list and 80 (33%) on the Green list. Twenty species moved on to the Red list since the previous assessment in 2009, but three moved to the Amber list and two were not assessed as they have ceased breeding.
