The Mas-Afuera rayadito is a small bird that lives only on one island in the Pacific Ocean off the coast of Chile. It has brown plumage, a sharp beak, and a long tail.
The Mas-Afuera rayadito differs from related species by living only on one small island. It is important for the island's nature because it eats insects and serves as part of the unique island ecosystem.
Legendary longevity: over 100 years. Galapagos tortoises, Greenland sharks, ocean quahogs celebrate with family once every 4 years
