The fork-tailed forest swallow is a small bird from the swallow family. It lives only on the Galapagos Islands and catches insects right in the air.
The fork-tailed forest swallow differs from other swallows by its deep tail notch and the fact that it is only found on the Galapagos Islands. It is important for nature because it reduces the number of insects.
Low precipitation in winter
Legendary longevity: over 100 years. Galapagos tortoises, Greenland sharks, ocean quahogs celebrate with family once every 4 years
