The Sumatran blue niltava is a small bird of the flycatcher family. It lives only in the mountain forests of Sumatra, males are bright blue, and females are brown.
The Sumatran blue niltava stands out with the bright blue coloration of males from other flycatchers. It helps the forest by eating harmful insects. The species is very rare and needs protection.
Legendary longevity: over 100 years. Galapagos tortoises, Greenland sharks, ocean quahogs celebrate with family once every 4 years
