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.
Akekee
The Akekee is a critically endangered Hawaiian honeycreeper weighing about 11 g with a wingspan near 12 cm. Endemic to the upland forests of Kauai, it uses its uniquely twisted bill to pry open leaf buds and extract insects, and is severely threatened by avian malaria and habitat loss.
