The large black-headed grosbeak is a large bird of the finch family with a very powerful beak. It inhabits the forests of East Asia and feeds mainly on hard seeds.
The large black-headed grosbeak differs from other finches by its very thick blue beak and the completely black head of males. It plays an important role in the forest because it spreads tree seeds.
Legendary longevity: over 100 years. Galapagos tortoises, Greenland sharks, ocean quahogs celebrate with family once every 4 years
