The red-tailed hilacola is a small bird 12–15 centimeters long. It lives in Australia among dense bushes and on the ground, where its rufous tail helps distinguish it from other species.
The red-tailed hilacola differs from related species by its bright chestnut color at the base of the tail. It is important for nature because it eats many insects and serves as prey for snakes and birds of prey.
Legendary longevity: over 100 years. Galapagos tortoises, Greenland sharks, ocean quahogs celebrate with family once every 4 years
