Although Ireland has fewer breeding species than Britain and Continental Europe (because there are fewer habitat types, fewer deciduous woodlands, Scots pine forests, heaths, and high mountain ranges), there are important populations of species which are in decline elsewhere. Storm petrels (largest breeding numbers in the world), roseate tern, chough, and corncrake. Four species of bird have Irish subspecies. These are the coal tit ("Parus ater hibernicus"), dipper ("Cinclus cinclus hibernicus"), jay ("Garrulus glandarius hibernicus"), and red grouse (" Lagopus lagopus hibernicus").
