• Albatross — A large seabird of the order Procellariiformes, characterized by extremely long and narrow wings allowing an unpowered gliding flight over huge distances, a strong and hooked bill provided with nasal tubes, and webbed feet. In literature and maritime myth, the bird is often a symbol of freedom, solitude, or the traveler's destiny, being symbolically protected by sailors' superstitions.
• Auk — A medium-sized seabird of the family Alcidae, distributed across arctic and temperate regions of the Northern Hemisphere. It features black-and-white plumage resembling that of penguins, short wings excellently utilized for swimming and deep underwater diving in search of food (small fish and crustaceans), but which also allow a rapid, though heavy-takeoff flight.
• Alcid — A generic name given to seabirds of the Alcidae family (alcids), order Charadriiformes, distributed across the cold seas of the Northern Hemisphere (such as the auk, puffin, guillemot). They are birds excellently adapted structurally for pelagic life, featuring dense black-and-white plumage, short wings used as powerful underwater flippers, and the capacity to dive to great depths to fish.
• The alcid — The definite articulated singular form of the noun 'alcid'; a seabird belonging to the Alcidae family, characteristic of the cold regions of the Northern Hemisphere. The term structurally defines the representative individual of this group of pelagic flyers perfectly adapted for swimming and diving at microscopic depths.
