Wetlands in the Biebrza Valley, north-east Poland, are inhabited by two closely related Aquila species: the more numerous Lesser Spotted Eagle A. pomarina prefers human-transformed landscapes, whereas the very rare Greater Spotted Eagle A. clanga is associated with natural marshy landscapes. At least since the last decade of the 20 th century, thes...
Article
Foraging sites of Aquila clanga compared to Aquila pomarina are characterized by a considerably longer duration of flooding within the year and higher mean and maximum depths of flooding. A. clanga is particularly associated with shallow (approx. 20 cm) spring flooding, lasting at least up to the beginning of May (on average up to 90 days per year)...

We conducted a pilot study to investigate breeding dispersal and ranging behaviour of two adult female Great Grey Owls in central Belarus. The females stayed within a few kilometres of their breeding site and ranged only 2–3 km on average and at night.
Article
Wetlands are often exposed to reed and shrub expansion that dominate their heterogeneous landscape and threaten species inhabiting open wetlands. The alternative to heavy-machine mowing is grazing, which should be carried out without fencing in high-value protected areas. To evaluate the effectiveness of semi-free-ranging cattle in sustaining and r...

Agriculture intensification drives changes in bird populations but also in the space use by farmland species. Agriculture in Eastern Europe still follows an extensive farming model, but due to policy shifts aimed at rural restructuring and implementation of government subsidies for farmers, it is being rapidly intensified. Here, we aimed to documen...
Article
Animal home‐ranges are expressions of the biology and ecology of a species and their size is often considered a proxy for habitat quality. Understanding the factors affecting variation in home‐range size may aid prediction of the impact of local or global environmental change on studied populations. To this end, we established an international coll...
Article
Urban forests are important hotspots of biodiversity in the environment of cities and their surroundings but may also stand out from neighbouring forests by greater tree species diversity, higher tree age and greater share of deciduous species. However, they are usually not connected with nesting of rare birds of prey, especially dietary specialist...

Study of migratory movements of spotted eagles using color tagging and tracking by means of GSM transmitters.
Project
The goal of the project is to examine various intrinsic and extrinsic factors shaping spatiotemporal patterns of migration among raptors. So far, we have been focusing on large and medium-sized species, such as the osprey, greater and lesser spotted eagles, buzzards and harriers, and we target the populations breeding in north-eastern Europe.
Project
This long-term project aims to reveal previously unexplored secrets in ecology of the two threatened spotted eagle species, Greater Spotted Eagle Clanga clanga and Lesser Spotted Eagle Clanga pomarina. We apply a wide array of methods, such as field biology, GPS-tracking, camera trapping and genetics, to study the eagles in their breeding and wintering grounds, as well as during migration. The ultimate goal is to support conservation of the species by providing national and international action plans with new knowledge to design the most appropriate actions.
