OBIS Australia Open in mapper Explore occurrences

The arctic tern Sterna paradisaea completes the longest known annual return migration on Earth, traveling between breeding sites in the northern arctic and temperate regions and survival/molt areas in the Antarctic pack‐ice zone. Light‐level geolocators were used to record 12 annual journeys by eight individuals of arctic terns breeding in the Baltic Sea.
