Warm, dry, open country with scattered trees and nest holes. Breeds in tree cavities, earth banks, and nest boxes.
Hawfinch
Deciduous and mixed woodland, orchards, parks, and large gardens with mature fruiting trees.
Song & Call Comparison
European Roller
A harsh, grating 'rack-rack' or 'quarrk' in flight. Gives a variety of sharp nasal calls at the nest. Not melodic; primary vocalizations are alarm and contact calls.

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.
Hawfinch
The hawfinch possesses the most powerful bill relative to body size of any European bird, capable of cracking cherry stones that require a force of 27-43 kg. Despite its distinctive appearance, it is famously shy and difficult to observe. The skull contains special adaptations to absorb the enormous forces generated during seed-cracking.
