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.
Short-billed Gull
Short-billed Gull, 40–45 cm, breeds in interior Alaska and western Canada, wintering on the Pacific coast. Recently split from Common Gull; slightly smaller with a shorter bill and more rounded head. Omnivore; often inland on grasslands and agricultural fields during migration. Migratory.
