Research interests

Adopting different approaches I am investigating various aspects of brood parasitism and migratory connectivity in birds and their consequences for reproductive performance and population ecology.

Running projects

Geographical gradients of avian diversity in sub-Saharan Africa: A life history perspective

Linking events through the annual cycle: the importance of carry-over effects for the ecology of migratory birds

The importance of migratory connectivity for the population ecology of long-distance migrants: a model study on the Reed Warbler (Acrocephalus scirpaceus)

Finished projects

European Reed Warbler populations across a migratory divide: insights into migration by analyses of DNA sequences, stable isotopes and ringing recoveries

Please, feel free to send me an e-mail if you need PDF copies of my papers.

Other activities

The yellowhammer was the Bird of the Year 2011 in the Czech Republic. Please, join the accompanying project Dialects of Czech Yellowhammers that aims at exploring the distribution of dialects in the Czech Republic and at promoting citizen science among amateur ornithologists. The project will expand to the UK and New Zealand in 2013.
