The name "Royal Tern" is believed to have originated from the bird's elegant appearance and graceful demeanor. The word "Royal" in the name may reflect the regal or majestic look of these terns. Their striking black cap, distinctive black line below the eye, and overall sleek appearance could contribute to the perception of royalty.

Royal Terns typically breed in colonies on coastal islands and sandy beaches. They often nest in the vicinity of other tern species, forming mixed colonies

These birds are known for their extensive migrations. They breed along the coasts of North and South America and migrate to warmer regions during the non-breeding season.
