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.
Common Nightingale
The common nightingale is celebrated as one of the finest songsters in the bird world, inspiring poets from Homer to Keats. Males sing complex phrases of over 250 different types, often at night during breeding season. Despite its famous song, the nightingale is a plain-looking bird that skulks in dense vegetation.
