Rynchops
Rynchops is a genus of skimmers, seabirds that catch small fish by flying low and cutting the water’s surface with an elongated lower bill.
Skimming (feeding behavior): A feeding method in which an animal moves through water with part of its body or a specialized structure submerged. Rynchops species skim with the lower bill immersed, snapping it shut when it contacts prey.
Skimmer: A seabird in the subfamily Rynchopinae, distinguished by a laterally compressed bill with an elongated lower mandible. Rynchops is the sole living genus in the skimmer subfamily.
Black skimmer: A North and South American skimmer species with black upperparts and a white underside. It is the best-known New World member of Rynchops and breeds in large colonies.
Fishery: The harvesting of wild fish or other aquatic organisms for food or commerce. Fishing can affect prey availability and disturb skimmer feeding areas.
Avian bill: The keratin-covered jaws of a bird, shaped and adapted for different feeding and other functions. The skimmers’ bills are unusually specialized: the lower mandible is longer than the upper.
Laridae: A family of aquatic birds that includes gulls, terns, and skimmers. Modern classifications place skimmers within this broader seabird family.
Indian skimmer: A South Asian skimmer species found on rivers and coastal wetlands. Its range and declining populations make it a distinctive conservation case within the genus.
Wetland loss: The reduction or destruction of wetlands through drainage, development, pollution, or altered water flows. Loss of shallow wetlands removes feeding and nesting habitat used by skimmers.
Tactile foraging: Finding food through touch rather than relying chiefly on sight. A skimmer can detect prey by contact as its bill moves through the water.
Seabird: A bird that obtains much of its food from marine or coastal waters. Most Rynchops species forage along coasts, estuaries, and large rivers.
