Cool Facts:
The Royal Tern makes its nest scrape on the ground on low-lying islands. The pair defecates directly on the nest rim, perhaps to reinforce the nest against flooding. After a few weeks, the nest rim hardens.
Young Royal Terns leave the nest scrape within one day after hatching and congregate together in a group known as a crèche. Eventually all of the chicks in a colony come to the crèche, which can have thousands of chicks ranging in age from two to 35 days old. A pair of Royal Terns will feed only their own chick, and manage to find it in the crowd, probably by recognizing its call.
