Hawfinch
Britain's most powerful-billed finch — the hawfinch has a massive, pale bill capable of cracking cherry stones and olive pits that require 50–70 kg of force to split; a bulky, short-tailed finch with rich chestnut, black, and white plumage and a distinctive white wing bar; notoriously shy and elusive, spending most of its time in high tree canopy and often detected only by its sharp call.
