Blood‐specific isotopic discrimination factors in the Magellanic penguin ( Spheniscus magellanicus ) [PDF]
Rationale The use of stable isotopes for ecological studies has increased exponentially in recent years. Isotopic trophic studies are based on the assumption that animals are what they eat plus a discrimination factor.

Ultrastructural aspects of the tongue in Magellanic Penguins Spheniscus magellanicus (Forster, 1781)
The tongue of birds presents diversified morphologic characteristics, related directly their feeding habits and may be adapted to food capture. Penguins of the Spheniscidae family are pelagic birds that are totally adapted to the marine environment. The

Late onset of cerebellar cortical degeneration in a Magellanic penguin (Spheniscus magellanicus). [PDF]
An 8-year-old female Magellanic penguin (Spheniscus magellanicus) started to show epilepsy-like seizures. Subsequent magnetic resonance imaging (MRI) examinations did not reveal any responsible lesions. The neurological symptoms worsened at the age of 10. This penguin became recumbent and died 6 months later after the apparition of the recumbency.

MHC Diversity and Mate Choice in the Magellanic Penguin, Spheniscus magellanicus [PDF]
We estimated levels of diversity at the major histocompatibility complex (MHC) class II DRß1 gene in 50 breeding pairs of the Magellanic penguin and compared those to estimates from Humboldt and Galapagos penguins. We tested for positive selection and 2 conditions required for the evolution of MHC-based disassortative mating: 1) greater MHC diversity ...

Reducing bumblefoot lesions in a group of captive Magellanic penguins (Spheniscus magellanicus) with the use of environmental enrichment [PDF]
Captive penguins are prone to pododermatitis (bumblefoot) lesions due to sedentary habits, changes in normal activity patterns, prolonged time on hard and abrasive surfaces, and less time swimming in the water.
