Department of Behavioural Ecology is a research group at the Faculty of Biology of Adam Mickiewicz University established by Tomasz Osiejuk and Piotr Tryjanowski (now in Institute of Zoology, University of Life Sciences, Poznań) on 1st December 2004.

In our research we focus on several aspects of behavioural ecology. Most particularly we are interested in acoustic communication and signalling, sexual selection, and habitat selection. We work mostly on birds but we do not hesitate to expand to other taxa, which may be useful for testing hypotheses and have nervous system developed. The most significant topics of our previous studies involved acoustic individual discrimination, territorial defense, mechanisms maintaining honesty of acoustic signals, and links between signal structure and meaning.
We focus on such model species like buntings (Emberiza spp.), corncrake (Crex crex), but with help of co-workers we also studied pipits (Anthus spp)., warblers (Acrocephalus spp.), skylark (Alauda arvensis) among others. Recently, more and more we do on African species in Cameroon. Since 2007 we spent there regularly 2-3 months per year. We study behaviour of duetting species like Chubb’s Cisticola (Cisticola chubbi) and Yellow-breasted Boubou (Laniarius atroflavus). One of the projects concerns effects of deforestration on avian biodiversity in Cameroon Mountains.
W cooperate with researchers from Australia, Belarus, Cameroon, Czech, France, Norway, Slovakia and USA. We hope that we are one of the best teams investigating animal behaviour in this part of Europe, and we are open for any new cooperation proposals.
