Focus of scientific research

I have been working in the field of avian biology since 1993. My major research interest is seasonal migration as a tool for the study of microevolution of birds. I have also worked on the fauna, reintroduction and ecology of endangered and rare bird species.

The main focus of my research is on the microevolution of birds. My research is broadly in population ecology with particular emphasis on the responses of individuals to changing environmental conditions and the proximate factors influencing these responses. I am interested in evolutionary consequences of bird migration and of the adaptive significance of migratory habits as well as to the migrants’ flexibility in responding to environmental changes.

At present, I am interested in the norm of reactions and adaptive radiation in performance of the seasonal migration in birds. After the large scale investigations of this adaptation in birds I am interested now in the study of the process in details. My research group works primarily on wild populations of birds since these offer excellent opportunities for testing a number of theoretical predictions in this area. Recent work has focused variability in orientation behaviour, physiological conditions of the migrants and terms of migration at specific and population levels.

We have also worked on captive birds and on methods for reintroduction in nature of endangered species of birds and conservation aspects of bird migration. I have been also involved in a project of impact estimation of wind turbines on the migrating birds along the Bulgarian Black Sea coast.

I have recently been interested in the molecular approach to population studies and in my group we currently have a number of ongoing studies in this area. Bird parasite interaction and its concequences on the population proceses are studied both in experimental and natural infected Gread Reed Warblers (Acr. arundinaceus). The polymorphism of the population in Gentoo Penguins (P. papua) from Livingstone island, Antarctica and Paddyfiel Warblers (Acr. agricola) with most western breeding population in Bulgaria have been studied.

I collaborate with a number of colleagues both here in Bulgaria and abroad.

Past projects

  • The role of the Balkan region in the Palearctic-African migration system: A quantitative estimate of the spatial and temporal distribution of nocturnal bird migration. (1999 – 2002) Simultaneous large-scale moonwatching observations in South Eastern Europe (1999 – 2003). Joint research project of the Institute of Zoology, Bulgarian Academy of sciences and the Swiss Ornithological Institute.
  • Reintroduction in the nature of rare and endangered bird species: Ruddy Shelduck (Tadorna ferruginea), Ferruginous Duck (Aythya nyroca) and Great bustard (Otis tarda). (1999 – 2001) The project involved development of schemes for captive breeding and reintroduction of endangered bird species.
  • Radio-satellite tracking of Red-breasted geese (Branta ruficollis) and Lesser White-Fronted Geese (Anser erythropus) wintering in Bulgaria.(1996 – 1997) Series of experiments on the globally threatened Red-breasted Goose and Lesser White-fronted Goose. Various ways of transmitter fixing have been explored. An implementation of a program for satellite tracing of the migratory ways of these two geese species.

Present projects

  • Migratory connectivity and migration pattern of a Palaearctic long-distance migrant. Swiss Ornithological Institute Joint Research Project

The project will determine (i) the over-wintering distribution of individuals from different populations, (ii) assess migratory connectivity of populations, and (ii) investigate individual migration patterns. To this end, we will employ up-to-date methods providing complementary information: First, we will use a novel ultra-light device for direct and continuous position measurements, that will allow us to localise the wintering areas of our study populations, to detect movements in the wintering areas, and to follow individual birds during their migration. Second, we will infer to habitat choice of individuals in over-wintering areas on a small spatial scale using the stable isotope pattern of claw tissue and the simultaneous measure of the bird’s position using geolocators.

  • Experimental stuy of bird malaria. Lund University, Swedish Research Council, Carl Tryggers Foundation

Bird malaria interaction in experimentally designed conditions and in the wild populations. Large scale screening of the hosts. Relation of the existing morphospecies with the Cyt. B. lineages of the haemosporidian parasites of birds.

  • Connectivity in European Paddyfield Warbler (Acrocephalus agricola Jerd.) – avian malaria and genetic variability of the population. European Science Foundation, ConGen program. Grant number: OEX/1150. For more information
  • Comparative population and monitoring research on Gentoo penguins (Pygoscelis papua) in Antarctica.INTAS project. The project is a part of the scientific program of the Bulgarian Antarctic Expeditions 2002 - 2005. For more information

Project aim: evaluation of the level of phenotypic and genotypic variability in Gentoo penguins within and between colonies. The project involves micro-satellite analysis of samples collected from different colonies, mithochondrial DNA analysis and field measurements of Gentoo penguins: body weight, bill and flipper length, as well as egg mass and size measurements.
