The red-sided astrild is a small bird about 11 centimeters long. It lives only on the island of São Tomé off the west coast of Africa and has gray plumage with bright red sides.
The red-sided astrild differs from related species by bright red sides and a limited range on one island. It is important for nature as a seed disperser of plants and part of the unique island ecosystem.
Legendary longevity: over 100 years. Galapagos tortoises, Greenland sharks, ocean quahogs celebrate with family once every 4 years
