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 Rosy-finch
The Black Rosy-finch is an endangered, medium-sized finch with jet-black body plumage and rose-pink wing and rump patches that give the rosy-finch group their name. It breeds at high altitude in rocky alpine terrain of the Rocky Mountains in the western United States, nesting in cliff crevices and talus slopes above the snowline. It feeds on seeds, insects, and invertebrates found at the snow's edge and in alpine meadows.
