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.
Akiapolaau
The Akiapolaau is an endangered Hawaiian honeycreeper weighing about 27 g with a wingspan near 15 cm. Endemic to the Big Island of Hawaii, it is notable for its highly specialised bill — a short, straight lower mandible for hammering and a long, curved upper mandible for probing bark for beetle larvae.
