Ardenna tenuirostris, commonly known as the slender-billed albatross, is a seabird belonging to the family Diomedeidae. This species is characterized by its long, narrow bill and impressive wingspan, which can reach up to 2.5 meters. It primarily inhabits the southern oceans, particularly around New Zealand and Australia, where it feeds on fish and squid. The slender-billed albatross is known for its remarkable gliding ability, allowing it to cover vast distances with minimal energy. It typically nests on remote islands, where it lays a single egg. Conservation efforts are in place to protect this species, as it faces threats from fishing bycatch and habitat loss.
