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.
Superb Fairywren
The superb fairywren is one of Australia's most beloved and recognizable birds, with breeding males dressed in spectacular violet-blue plumage. These tiny birds live in cooperative family groups where helpers assist the breeding pair in raising young. Males pluck and present yellow flower petals to females as part of courtship.
