During the period 15 August — 1 November 2020 “Durankulak 2020” bird ringing camp was organised with the substantial financial help of National Museum of Natural History at the Bulgarian Academy of Sciences. The camp was situated on the shores of Durankulak Lake, NE Bulgaria, very close to the Black Sea coast. During the campaign in the camp were captured and ringed 13 786 birds representing 93 species.
The most numerous were Yellow Wagtail (Motacilla flava), Barn Swallow (Hirundo rustica), Robin (Erithacus rubecula), Reed Warbler (Acrocephalus scirpaceus) and Sedge Warbler (Acrocephalus schoenobaenus). We had four recaptures of birds ringed abroad — from Belarus, Finland, Slovakia and Romania. We had also some recaptures from Durankulak from the previous autumn. We succeeded to capture three very rare new species for the Bulgarian avifauna — Yellow-browed Warbler (Phylloscopus inornatus), Dusky Warbler (Phylloscopus fuscatus), and Red-flanked Bluetail (Tarsiger cyanurus). Dusky Warbler was found for the first time for the Bulgarian fauna and Red-flanked Bluetail — for second time.
More than 75 experts, ringers and volunteers took participation in the camp that autumn. Many of them obtained new knowledge and skills on field ornithology. We thank to all the participants for their valuable help.
