Postmortem findings in Magellanic penguins (Spheniscus magellanicus) caught in a drift gillnet

BMC Veterinary Research, 2020
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

How much is too much? Assessment of prey consumption by Magellanic penguins in Patagonian colonies. [PDF]

PLoS ONE, 2012
Penguins are major consumers in the southern oceans although quantification of this has been problematic. One suggestion proposes the use of points of inflection in diving profiles ('wiggles') for this, a method that has been validated for the estimation

Parental Quality and Selection on Egg Size in the Magellanic Penguin [PDF]

Evolution, 1990
We examined the relative contributions of egg size and parental quality to hatching success, fledging success, and chick growth in the Magellanic penguin (Spheniscus magellanicus) be exchanging clutches between nests to reduce the covariation between egg and parental factors.

Genetically diverse herpesviruses in South American Atlantic coast seabirds.

PLoS ONE, 2017
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 ...

Variability in Foraging Range and Direction Among Colonies in a Widespread Seabird, the Magellanic Penguin

Frontiers in Marine Science, 2022
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.

Outbreak of avian malaria associated to multiple species of Plasmodium in magellanic penguins undergoing rehabilitation in southern Brazil. [PDF]

PLoS ONE, 2014
Avian malaria is a mosquito-borne disease caused by Plasmodium spp. Avian plasmodia are recognized conservation-threatening pathogens due to their potential to cause severe epizootics when introduced to bird populations with which they did not co-evolve.

P465 Aspergillosis in free-ranging Magellanic penguins

Medical Mycology, 2022
Abstract Poster session 3, September 23, 2022, 12:30 PM - 1:30 PM Aspergillosis is an opportunistic fungal disease caused by the Aspergillus genus, mostly by Aspergillus section Fumigati. Captive Magellanic penguins are vulnerable to Aspergillus infection, being this mycosis a limiting factor during ...

Tangled and drowned: a global review of penguin bycatch in fisheries

Endangered Species Research, 2017
Penguins are the most threatened group of seabirds after albatrosses. Although penguins are regularly captured in fishing gear, the threat to penguins as a group has not yet been assessed.

Little penguins select more isolated nest boxes for breeding, but lay date influences breeding success

The Journal of Wildlife Management, Volume 90, Issue 6, August 2026.
We determined that more isolated and possibly older nest boxes were selected by little penguins for breeding at Pōhatu/Flea Bay, New Zealand. However, breeding success was influenced by lay date in comparison to nest box characteristics. These findings inform immediate conservation recommendations regarding nest box design and placement.
