<abstract xmlns="http://www.w3.org/1999/xhtml"><p> In 2015, 170 bird species were recorded during bird ringing activities in Slovenia. We ringed 73,371 birds belonging to 162 species, there were 132 foreign recoveries of birds ringed in Slovenia, 120 recoveries of birds ringed abroad and found in Slovenia, as well as 1964 local recoveries. The most frequently ringed species were Blackcap Sylvia atricapilla and Great Tit Parus major. In ringed nestlings, Great Tits and Tree Sparrows Passer montanus predominated. In 2015, the first preliminary ringing of Scops Owls Otus scops during migration took place, resulting in the highest number of Scops Owls ringed so far. Concerning recoveries of birds ringed in Slovenia and later recorded abroad and birds ringed abroad and later recorded in Slovenia, the commonest were Mute Swans Cygnus olor and Black-headed Gulls Chroicocephalus ridibundus. The longest-distance recovery concerned a Reed Bunting Emberiza schoeniculus found in Sweden (2,144 km away).
