How not to overread the picture

Variation: Age and molt alter appearance; colony context is behavior, not a body-plan character.

Representation: The same taxonomic class as a falcon can produce a radically different silhouette when flight is traded for underwater propulsion.

Process / function synthesis: A flightless bird specialized for Antarctic marine foraging and breeding on sea-ice/coastal environments.

Evidence note

ADW documents Antarctic distribution, bird classification, and a diet centered on fish, crustaceans, and molluscs.
