Poročilo o obročkanju ptic v Sloveniji v letu 2016 in pojavljanje mušje listnice Phylloscopus inornatus v 25 letih v Sloveniji

Abstract In 2016, data on 176 bird species were gathered during bird ringing activities in Slovenia. A total of 65,711 birds of 165 different species were ringed. Furthermore, 148 recoveries of birds ringed in Slovenia and found abroad, 245 foreign recoveries in Slovenia and 1840 local recoveries were made. The most frequently ringed species was the Blackcap Sylvia atricapilla. Among the ringed nestlings, Great Tits Parus major, Tree Sparrows Passer montanus and White Storks Ciconia ciconia predominated. Considering recoveries of birds ringed or found abroad, the most frequent were finds based on colour rings, especially of Black-headed Gulls Chroicocephalus ridibundus, Mute Swans Cygnus olor and Common Terns Sterna hirundo. As far as local recoveries are concerned, most data were collected for Great Tit and Siskin Spinus spinus. Among rare species, two Yellow-browed Warblers Phylloscopus inornatus were ringed, one Paddyfield Warbler Acrocephalus agricola, one Little Emberiza pusilla and one Black-headed Bunting Emberiza melanocephala, the latter as a singing male, which probably also bred in 2016. The catch frequency of the Yellow-browed Warblers has indeed been increasing in Slovenia in the last 25 years, but this is still a rare and irregular vagrant on autumn migration.
