The elegant tern (Thalasseus elegans) belongs to the Laridae and Charadriiformes orders of seabirds.
Over 90% of all elegant terns nest in a single colony. There only five known colonies exist, three on the southern California coasts and two in northeastern Mexico.
Their distribution and abundance are also dependent on its primary source of food—the Northern anchovy. When anchovies number is plentiful, terns have a high breeding success rate and vice versa.

On land, females lower their heads in a groveling posture, seeking food just like a chick, while males present them with a small fish, lifting the crest, holding high, and drooping the wings, all the while calling and flick the bill upward.
Later, in the air, the male and female fly together and glide in parallel, quickly raising the wings in sync in a V shape, gliding and calling together for 10 seconds or more, then repeating this beautiful order multiple times. So they are undoubtedly monogamous in mating.

Following mating, the female lays one or possibly two eggs. For four weeks, both parents incubate the egg and feed the chick.
The chick stays in the nest for about a week after hatching.
As soon as the chicks are active, the adults gather them into a crèche, but they can always recognize and feed their chicks in these groups. The parents continue to feed their chick long after it has fledged, and family groups stay together for at least six months after hatching.
