The Island Tit-tyrant is a small bird of the tyrant flycatcher family. It lives only on the Juan Fernández Islands off the coast of Chile and is not found anywhere else.
The Island Tit-tyrant differs from related species by its noticeable white crest and black-and-white coloration. It is important for the islands' nature because it eats insects and helps maintain balance in the forest.
Legendary longevity: over 100 years. Galapagos tortoises, Greenland sharks, ocean quahogs celebrate with family once every 4 years
