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.
European Herring Gull
European Herring Gull, 55–67 cm, wingspan 125–155 cm, is the archetypal large gull of Atlantic Europe. Silver-grey mantle, white body, yellow bill with red spot, pink legs. Omnivore; scavenges in cities and harbours; drops molluscs to crack shells. Partially migratory; declining in recent decades.
