First penguin fossil (Aves, Spheniscidae) from Uruguay
Journal of South American Earth Sciences, 2019Abstract A fossil humerus coming from the Rocha Department coasts (Uruguay) is assigned here to Spheniscus cf. S. magellanicus (Aves, Sphenisciformes). This finding, located within the current migratory route of the species, potentially constitutes the northernmost fossil record of S.

Abstract Modern penguins are typically small to medium-sized birds, and nearly all known modern specimens are smaller than the most archaic Paleogene relatives. Here we report an incomplete humerus, associated femur and tibiatarsus of a new spheniscid, Crossvallia unienwillia nov. gen.

Journal of Wildlife Diseases, 1988
Blood smears were examined from 143 penguins of four species (Aptenodytes patagonicus, Eudyptes chrysolophus, E. schlegeli, and Pygoscelis gentoo) from Sub-antarctic Macquarie Island and Heard Island. No blood parasites were reported. The vectors of Hepatozoon albatrossi (reported from three species of albatross) are probably shared by penguins, and it

The Energetics of Free-Living Little Penguins Eudyptula-Minor (Spheniscidae), During Molt
Australian Journal of Zoology, 1988Levels of circulating triglycerides and cholesterol in moulting little penguins in Tasmania were measured before, and throughout the moult. Levels at the initiation of moult were similar to those in breeding birds but increased by 2.5 times (triglycerides) and 1.8 times (cholesterol) during the moult.

Liver and plasma retinol (vitamin A) in wild, and liver retinol in captive penguins (Spheniscidae)
Journal of Zoology, 1989In rockhopper penguins (Eudyptes crestatus), liver concentrations of retinol (vitamin A) were significantly higher in post‐moult than in pre‐moult birds. In Magellanic penguins (Spheniscus magelianicus), plasma concentrations of retinol were significantly higher in post‐moult than in pre‐moult birds; liver retinol concentrations were also higher, but ...
