Biological Station Rybachy, Russia

During the year 2004, totally 47 587 birds of 106 different were species ringed at the Courish Spit. It is only 43,9% of our maximum, reached in year 1983, and slightly higher than yearly average for 1956-2003.
Most birds: 59% were caught with big Rybachy-type traps (27 865 birds of 91 species); 23% (11 060 birds of 75 species) – with mist-nets in Rybachy, 3% (1 582 birds of 25 species) were ringed as nestlings at the nests or in nestboxes, and 15% trapped with a use of other methods.
Comparatively numerous species were: Acrocephalus scirpaceus (62.9% of yearly maximum registered at our place), Dendrocopus medius (maximum of 9 birds was reached second time after the year 2001), Dendrocopus minor (89% of maximum registered), Hirundo rustica (86.8%), Lanius collurio (61.5%), Loxia curvirostra (68.2%), Parus palustris (68.2%), Phylloscopus collybita (72.6%) and Sylvia curruca (61.8%). Some birds of species, rare for the region, were trapped, for example 3 Certhia brachydactyla, 1 Hippolais calligata, 1 Loxia leucoptera, 7 Phylloscopus trochiloides and 5 Regulus ignicapillus.
Among ringed birds, 1781 individuals of 54 bird species were retrapped (caught at least twice the same year), thus 2 780 retraps were recorded. 487 birds of 39 species ringed at the Courish Spit before 2004 were retrapped in 2004.
152 birds of 27 species with foreign rings were controlled, and 114 birds of 27 species, ringed at the Courish Spit, found abroad. The most interesting recoveries analyzed were: the Reed Warbler that flew from the Courish Spit to Belgium in 9 days (more than 1200 km), Swallow’s recovery from South Africa (9461 km), Thrush Nightingale from Kenya (6689 km) etc.
Some aspects of migration timing and dynamics were discussed.
