About These Birds
Eurasian Eagle-Owl
The Eurasian eagle-owl is one of the largest owl species in the world, with females sometimes reaching a wingspan of nearly two meters. Its deep booming call can be heard up to four kilometers away on calm nights. These apex predators sit at the top of the avian food chain, preying on other raptors including buzzards and smaller owls.
European Roller
The European roller gets its name from the spectacular rolling and tumbling aerial displays performed by males during courtship. It is the only roller species in Europe and one of the continent's most colorful birds. Declining across much of its western range due to agricultural intensification and habitat loss.
