In 2003, 1723 birds from 68 species were ringed during the migration periods at Kalimok ringing station (41o00'N 26o26'E, NE Bulgaria). Birds were caught with mist-nets, situated in reedbeds and deciduous forest during the spring (7 March - 28 May) and the autumn (5 August - 14 October) season. Species from genus Acrocephalus, Phylloscopus trochilus and Passer hispaniolensis were most numerous.
Besides ringing, 711 orientation experiments with long-distance migrants were made. Birds were tested in two types of orientation cages – Busse cage for daytime tests and Emlen funnels for night tests. Strong prevalence of non-migratory directions was observed in some species. Main headings in reversed pictures coincide with the observed directions obtained with the moon-watch method for free-flying birds in this place.
