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-headed Siskin
The Black-headed Siskin is a small finch with a black head and throat, bright yellow body plumage, and dark wings with yellow patches. It inhabits montane pine-oak forests, forest edges, and semi-open areas from Mexico through Central America to Panama. It feeds on seeds, particularly those of pines and other conifers, often foraging in small flocks high in the trees.
