About These Birds

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.
