About These Birds
Arctic Tern
The Arctic tern holds the record for the longest known migration of any animal, traveling roughly 70,000 km annually from Arctic to Antarctic and back. Over its 30-year lifespan, it may fly the equivalent of three round trips to the Moon. This remarkable bird experiences more daylight than any other creature on Earth.
Eurasian Magpie
The Eurasian magpie is one of the most intelligent animals on Earth and the first non-mammal demonstrated to recognize itself in a mirror. These bold corvids build elaborate domed nests of sticks and have a well-known attraction to shiny objects, though this reputation may be exaggerated.
