Comparing plasma and faecal measures of steroid hormones in Adelie penguins Pygoscelis adeliae [PDF]
Physiological measurements of both stress and sex hormones are often used to estimate the consequences of natural or human-induced change in ecological studies of various animals.

Postmortem findings in Magellanic penguins (Spheniscus magellanicus) caught in a drift gillnet
Background Penguin interaction with gillnets has been extensively reported in the Atlantic and Pacific Oceans, and is considered a major conservation threat. Among penguin species, Magellanic penguins (Spheniscus magellanicus) are currently considered of

First record of feather-loss disorder in Antarctic penguins [PDF]
Little is known about diseases affecting Antarctic wildlife (Kerry & Riddle 2009). Understanding the patterns, causes and effects of disease in these populations is crucial as many of these species are already threatened by rapid environmental changes ...

Most seabirds forage far from land, making them hard to observe when foraging. Satellite tracking of seabirds shows where they come into conflict with human uses of the ocean, and whether they use protected areas.

Antennae on transmitters on free-living marine animals: Balancing budgets on the high wire [PDF]
The effect of externally mounted antennae on the energetics of penguins was studied by mounting various antennae on a transducer fixed to a model Magellanic penguin Spheniscus magellanicus to determine drag, run at speeds of up to 2 m s–1 in a swim canal.

Genetically diverse herpesviruses in South American Atlantic coast seabirds.
Different herpesviruses have been associated with respiratory and enteric disease and mortality among seabirds and waterfowl. In 2011, a respiratory disease outbreak affected 58.3% (98/168) of the Magellanic penguins undergoing rehabilitation due to an ...

Population Trends of a Mixed-Species Colony of Humboldt and Magellanic Penguins in Southern Chile after Establishing a Protected Area [PDF]
Worldwide marine protected areas (MPAs) have been designated to protect marine resources, including top predators such as seabirds. There is no conclusive information on whether protected areas can improve population trends of seabirds when these are ...

Lip-reading in remote subjects: An attempt to quantify and separate ingestion, breathing and vocalisation in free-living animals [PDF]
A new mandibular sensor is presented here based on the use of a Hall sensor, attached to one mandible, opposite a magnet, attached to the other mandible. Changes in sensor voltage, proportional to magnetic field strength, and thus inter-mandibular angle,

Patterns of respiration in diving penguins: Is the last gasp based on an inspired tactic? [PDF]
Humboldt penguins Spheniscus humboldti in captivity and free-living Magellanic penguins S. magellanicus were fitted with loggers to determine beak angles during breathing.
