The river tern or Indian river tern (Sterna aurantia) is a tern in the family Laridae, the largest species currently included in the genus Sterna of typical terns. It is a resident breeder along inland rivers from Pakistan east through the Indian subcontinent, to Myanmar, Thailand, and Cambodia, where it is uncommon. Unlike most Sterna terns, it is almost exclusively found on freshwater, rarely venturing even to tidal creeks. Wikipedia →

Global Distribution

Where this species is recorded worldwide. Restricted to human observations from 2019 onwards — the same kind of record and the same period the probabilities on this page are built from, so collar-tracking studies, camera-trap arrays and museum specimens are excluded. Around Santa Rosa that removes 5,924 GPS fixes from a handful of tagged jaguars.
