Royal Tern Audubon Field Guide Their large size, distinctive black cap, and graceful flight make them a favorite among birders and beachgoers alike. understanding their migration patterns and conservation needs is essential for ensuring their continued presence in our coastal ecosystems. This is a large tern, second only to the caspian tern among terns in the americas, but is unlikely to be confused with this "carrot billed" giant, which has extensive dark underwing patches.
Royal Tern Big Year Birding Royal terns fly gracefully and slowly along coastlines, diving for small fish, which they capture with a swift strike of their daggerlike bills. they are social birds, gathering between fishing expeditions on undisturbed beaches and nesting in dense, boisterous colonies. Separated from many terns by large size; only slightly smaller than caspian. look for the thinner orange bill (usually not deep red) and shaggier crest compared with caspian. The royal tern has similarities to the caspian and elegant terns. only the royal and the elegant terns have crested heads and the royal has the largest bill between the two. this large tern is seen along the atlantic coast, westward across the us states to the coastlines of texas. Breeding royal terns display a shaggy fully black crown. during the non breeding season (late summer, fall, and winter), royal terns lose most of their black crest and have a white forehead and black band on the back of the head.

Breeding for royal terns typically occurs in large, dense colonies on sandy or rocky islands, where they lay their eggs in shallow scrapes on the ground. the breeding season varies depending on the geographic location but often spans from april to june in north america. To identify the royal tern, look for its large size, pale grey upperparts, and white underparts. the orange red bill is a key feature, along with the black cap during breeding season. Common along tropical and subtropical shores, the royal tern is a characteristic sight along the gulf coast and southern atlantic coast, less numerous in california. aside from a few interior localities in florida, it is almost never found inland except after hurricanes. Breeding colonies of the royal tern favor traditional sites at isolated locations, free of terrestrial predators; in the united states, dredge spoil islands have become key to the survival and expansion of the species.
