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.
Black-and-yellow Grosbeak
The Black-and-yellow Grosbeak is a large, robust finch of montane conifer forests in the western Himalayas from Afghanistan to Nepal. Males are brilliant yellow below with black upperparts and a massive yellow bill adapted for cracking seeds. It feeds on pine seeds, buds, berries, and insects, often in small flocks.
