Habitat Comparison
Arctic Tern
Breeds on coastal and tundra habitats. Spends most of its life at sea over the open ocean. Nests in colonies on beaches and rocky shores.
Wandering Albatross
Open ocean of the Southern Hemisphere. Breeds on remote sub-Antarctic islands. Spends years at sea between breeding attempts.
Song & Call Comparison
Arctic Tern
A sharp, grating 'kree-yah' alarm call. Also gives 'kik-kik-kik' near the nest. Highly aggressive vocally during the Arctic breeding season. Calls are harsh and insistent.
Wandering Albatross
At nesting colonies emits a loud braying 'waaah' and guttural grunts. Silent at sea for most of the year. Courtship involves ritualized mutual bill-clapping and moaning calls.

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.
Wandering Albatross
The wandering albatross has the largest wingspan of any living bird, reaching up to 3.5 meters. These oceanic nomads can circumnavigate the globe, covering over 120,000 km per year using dynamic soaring with minimal wing flapping. Pairs mate for life and may live over 60 years.
