The rufous-tailed swamp tyrant is a small bird from the tyrant flycatcher family. It lives in wet thickets and swamps of South America and catches insects in flight.
The rufous-tailed swamp tyrant stands out with its bright rufous tail in males. It is beneficial to nature because it eats many insects and helps maintain balance in swamp areas.
Legendary longevity: over 100 years. Galapagos tortoises, Greenland sharks, ocean quahogs celebrate with family once every 4 years
