Research:

Behaviour of sparrows:
House sparrows (Passer domesticus) live in a variety of habitats, from rural farms to city centers. In our current projects we investigate the effects of habitat urbanization on sparrows’ behaviour, e.g. problem solving and response to novelty and predation hazard. We also study the fitness consequences of variation in problem solving both in the lab and in the wild. In these projects I work together with Dr. Veronika Bókony, Dr. Ádám Z. Lendvai, Krisztián Szabó, Prof. Zoltán Barta and Dr. Zsolt Pénzes. Many of our studies are conducted in the Zoo of Veszprém.

Waterfowl migration on Lake Balaton:
Large number of ducks, geese and other waterbirds migrate and winter on Lake Balaton (the largest lake in Hungary) and the surrounding wetlands. Using ringing and monitoring data, we investigate the sources of birds wintering on Lake Balaton, and the effects of habitat characteristics on their population size and spatial distribution. [with Katalin Pap and Dr. Lajos Nagy, Balaton Uplands National Park]

Comparative studies:
We use phylogenetic comparative methods to test various evolutionary hypotheses related to reproduction and life history in birds. Currently we investigate how ecological and social factors affect parental behaviour in a wide taxonomic range of birds. In earlier work we showed the effects of sexual selection on egg size, mortality, coloration and parental care, and provided the first demonstration that increases in brain size coevolved with higher survival rates. [with Prof. Rob Freckleton, Prof. Tamas Székely and Dr. Veronika Bókony]
