The South American Tern is a common and widespread tern along the coasts and large rivers of South America. It is similar to the Common Tern but distinguished by subtle plumage differences, particularly in its flight. This adaptable species is often seen foraging in coastal and inland waters.

Where to spot

Found along the Atlantic and Pacific coasts of South America, from Brazil to Tierra del Fuego, and inland along major river systems. Inhabits coastal beaches, estuaries, and large freshwater lakes.

How to spot

Look for its black cap (breeding), red bill (breeding), and grey upperparts. Distinguish from similar species by its slightly larger size and subtle plumage variations. Observe its graceful flight and characteristic plunge-dives for fish.

When to spot

Resident year-round in warmer parts of its range, migratory in southern regions during the austral winter. Breeding occurs during the austral spring and summer (September-February). Best observed during daylight hours along coastlines and rivers.
