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.
Azure Dollarbird
The Azure Dollarbird is a Near Threatened roller found in the North Maluku Islands of Indonesia, weighing about 122.8g with a wingspan of 38cm. It inhabits forest edges and open woodland, and like other dollarbirds catches insects on the wing with powerful aerial pursuits. Its striking azure-blue plumage makes it one of the most colorful rollers in its range.
