The Sandwich Tern (Thalasseus sandvicensis) is a medium-sized seabird belonging to the tern family, commonly found along coastal regions, estuaries, and sandy shores. Recognized by its slender build, pale gray upperparts, white underparts, and a distinctive black cap that recedes in winter, it also features a sharp, black bill with a yellow tip. This species is a skilled aerial fisher, hovering before diving into the water to catch small fish. Sandwich Terns are social birds, often seen nesting in large colonies with other seabirds, providing safety in numbers. During migration and winter, they travel along coastlines, moving between breeding and feeding grounds. In the UAE, they are frequently observed along the shores and wetlands, particularly during migration seasons. Their sharp, high-pitched calls and graceful flight make them a fascinating species for birdwatchers along coastal habitats.
