Population trends of widespread breeding birds in the Republic of Ireland 1998–2008

Capsule The first analyses of trends in relative abundance of terrestrial birds in Ireland showed that trends were predominantly stable or increased between 1998 and 2008. Aims To determine trends in relative abundance of common and widespread breeding birds in the Republic of Ireland between 1998 and 2008. Methods Changes in abundance of 52 species were described nationally, and at regional level, by fitting log‐linear regression models to transect data gathered as part of the Countryside Bird Survey between 1998 and 2008. Results Some 22 species were shown to increase, 8 species declined, and 22 species were relatively stable. Greatest increases were seen in Stonechats Saxicola torquata, Blackcaps Sylvia atricapilla, European Goldfinches Carduelis carduelis, Common Redpolls C. flammea, and Common Bullfinches Pyrrhula pyrrhula. The greatest declines in trends were in Common Kestrels Falco tinnunculus, Common Swifts Apus apus, Sky Larks Alauda arvensis and Mistle Thrushes Turdus viscivorus. Most of the na...
