Abstract

The area of Coastal Dobrudzha in NE Bulgaria is well known for its richness of vagrants. A long-term research project was started at a location at Durankulak Lake, on the northern Black Sea Coast, aiming to obtain data on the characteristics of autumn migration of passerine birds and on the presence of vagrants there. A total of 20 mist nets with an overall length of 200 meters were set between August and October in two different habitats - reed bed and broad-leaved forest. In 2019, a total of 9344 birds of 84 species were caught and ringed. In 2020, the number of the birds caught increased to 13786 of 93 species. Vagrants such as dusky warbler (Phylloscopus fuscatus), yellow-browed warbler (Phylloscopus inornatus) and red-flanked bluetail (Tarsiger cyanurus) were captured in 2020. Detailed information about these findings is given in the present work.

The area of maritime Dobrudzha is well known for its richness of vagrants and rare birds of different orders having eastern or northern origin like Phalaropus fulicarius, Charadrius mongolus, Lanius isabellinus, Serinus pussilus, Phylloscopus proregulus and many others (Dontschev, 1967; Mitev & Welsch, 2011; Simeonov, 2013; Ignatov et al, 2015; Simeonov, 2015)

Summary

Introduction

Autumn passerine migration is not systematically studied along the northern part of the Bulgarian Black Sea Coast. The area of maritime Dobrudzha is well known for its richness of vagrants and rare birds of different orders having eastern or northern origin like Phalaropus fulicarius, Charadrius mongolus, Lanius isabellinus, Serinus pussilus, Phylloscopus proregulus and many others (Dontschev, 1967; Mitev & Welsch, 2011; Simeonov, 2013; Ignatov et al, 2015; Simeonov, 2015). Along the North Bulgarian Black Sea Coast, records of vagrants are mostly a result of intensive field monitoring. Occasional short term ringing activities, mostly during summer and autumn, had been carried out at Durankulak Lake and Shabla Tuzla Lake (Dimitrov et al, 2018; own unpublished data)
