Report of the Swiss Ringing Scheme 1. Ringing In 2001, 86704 birds from 166 species were ringed and 962 recoveries were recorded (for details see Wiprächtiger et al. 2002). In 2002, 82654 birds from 175 species were ringed and 1083 recoveries were recorded (for details see Wiprächtiger et al. 2003). In June 2003, all Swiss ringing recovery data were transferred to the EURING data base. In 2002, the Sempach scheme introduced a special type of rings for raptors and owls released from captivity after recovery from injury or illness. In 2003, a new ring size (diameter 2,0 mm) was introduced for ringing wren, warblers, goldcrest, firecrest, long-tailed tit, treecreepers, and serin, as well as a new plastic ring for white stork (ELSA®-ring). Switzerland continued to participate in the EURING Swallow Project. Since 2000, 12 areas have been investigated during the breeding season. In all, breeding populations declined between 2000 and 2002 by 40%, due mainly to a higher mortality of young Swallows in these years which has probably been caused by bad weather conditions during migration. Ringing activities in roosts continued as well and resulted in 6885 birds ringed and 104 recaptured in 2001 (15 roosts) and 5449 resp. 107 in 2002 (14 roosts). 2003 will mark the end of the field activities within the Swiss Swallow Project. The nation-wide Integrated Population Monitoring Programme for the Kestrel Falco tinnunculus and the Barn Owl Tyto alba continued. It aims at studying (1) how population changes are reflected by population parameters and (2) how they disperse. A study on local population dynamics in barn owls was published (Altwegg et al. 2003). 2. Administration The Swiss Ringing Scheme is based at the Swiss Ornithological Institute, Sempach. The Ringing Scheme is being financed by the Swiss Agency for the Environment, Forests and Landscape SAEFL. The contract for this invaluable support has been extended until 2005. 4 candidates sucessfully passed the ringer's examination in 2001, and 14 in 2002. 3. Staff The following staff worked within the Ringing Scheme: An advisory board of six highly experienced ringers is assisting the Sempach scheme. Lukas Jenni kept serving as General Secretary of EURING. 4. Publications 4.1 Publications of the ringing scheme Altwegg, R., A. Roulin, M. Kestenholz & L.
