Order: Charadriiformes
Family: Laridae
The Royal Tern is a striking seabird found along the coasts of Patagonia, easily identified by its slender, orange bill, black cap, and graceful flight. Adults have pale gray upperparts and white underparts, with a distinctive black line running from the eye to the nape during the breeding season. Outside of breeding, the black cap recedes, leaving a mottled appearance. Royal Terns are highly social, gathering in large flocks both when roosting and nesting. Their loud, harsh calls are a familiar sound along sandy beaches and estuaries. They are agile fliers, often seen hovering briefly before plunging into the water to catch fish. In Patagonia, they are most commonly observed along the Atlantic coast, especially in protected bays and lagoons. Their presence is an indicator of healthy coastal ecosystems, as they rely on abundant fish populations. The Royal Tern’s elegant appearance and dynamic behavior make it a favorite among birdwatchers and coastal visitors.

Coastal beaches, estuaries, bays, and lagoons along the Patagonian shoreline.
