The royal tern nests on island beaches or isolated beaches with limited predators.
It lays one or two eggs, usually in a scrape, an area on the ground where a tern has made a small hole to lay its eggs.
In some cases, tern eggs are laid directly on the ground, not in a scrape.
The eggs incubate from 25 to 30 days; after the eggs hatch the chicks remain in the scrape for about a week.
About two weeks after hatching the chicks gather into groups called a crèche.
When the chicks are in the crèche, they are primarily fed by their parents who recognize their offspring by their voice and looks.
While the chicks are in the crèche, they usually roam freely around the colony.
In a large colony there can be thousands of chicks in the crèche.
When the chicks are a month old they fledge or start to fly.
Royal terns mature around the age of 4 years, after which they build their own nests and reproduce.

Like all white terns, it is fiercely defensive of its nest and young.
The royal tern and the Cayenne tern nest and breed together in Argentina and Brazil.
