About These Birds
Black-headed Greenfinch
The Black-headed Greenfinch is a medium-sized finch with a black head, dark olive-green body, and bright yellow wing patches and tail edges. It inhabits open forest, secondary growth, and scrubby hillsides from northeastern India through southern China and Vietnam. It feeds on seeds, berries, and buds, often foraging in the forest canopy and along woodland edges.
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.
