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.

Yellow-legged Gull, 52–68 cm, is the large gull of Mediterranean and Atlantic Iberian coasts. Yellow legs distinguish it from the pink-legged Herring Gull; darker grey mantle. Omnivore; highly adaptable — increasing in urban areas and landfills across southern Europe and North Africa.
