About These Birds
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.
Shoebill
The shoebill is one of the most sought-after birds for birdwatchers visiting Africa, prized for its prehistoric appearance and massive bill. It can stand motionless for hours before collapsing forward to seize prey in its enormous bill. Despite standing over a meter tall, shoebills weigh relatively little due to their hollow bones.
