Fine-scale dietary changes between the breeding and non-breeding diet of a resident seabird [PDF]
Royal Society Open Science, 2015 Unlike migratory seabirds with wide foraging ranges, resident seabirds forage in a relatively small range year-round and are thus particularly vulnerable to local shifts in prey availability.

Carry-over body mass effect from winter to breeding in a resident seabird, the little penguin [PDF]
Royal Society Open Science, 2015 Using body mass and breeding data of individual penguins collected continuously over 7 years (2002–2008), we examined carry-over effects of winter body mass on timing of laying and breeding success in a resident seabird, the little penguin (Eudyptula ...

An Overview of the Penguin Visual System
Vision, 2023 Penguins require vision that is adequate for both subaerial and submarine environments under a wide range of illumination. Here we provide a structured overview of what is known about their visual system with an emphasis on how and how well they achieve ...

Changes in diet and trophic position of a top predator 10 years after a mass mortality of a key prey [PDF]
, 2012 After the disappearance of primary prey, seabirds exhibit gradually decreased breeding performance, and eventually the population size drops. Results are presented of an investigation into the diet of little penguins (Eudyptula minor) at Phillip Island ...

First record of feather-loss disorder in Antarctic penguins [PDF]
, 2014 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 ...

Time-lapse imagery of Adélie penguins reveals differential winter strategies and breeding site occupation. [PDF]
PLoS ONE, 2018 Polar seabirds adopt different over-wintering strategies to survive and build condition during the critical winter period. Penguin species either reside at the colony during the winter months or migrate long distances. Tracking studies and survey methods

Impacts of local human activities on the Antarctic environment [PDF]
, 2008 We review the scientific literature, especially from the past decade, on the impacts of human activities on the Antarctic environment. A range of impacts has been identified at a variety of spatial and temporal scales.

Sexing Galápagos penguins Spheniscus mendiculus by morphological measurements
Endangered Species Research, 2018 The ability to identify the sex of individuals is essential in studies of ecology, behavior, and conservation, but reliable methods for sexing species that exhibit low sexual dimorphism are often time consuming or invasive.

Trophic niches of a seabird assemblage in Bass Strait, south-eastern Australia [PDF]
PeerJ, 2020 The foraging niches of seabirds are driven by a variety of factors, including competition for prey that promotes divergence in trophic niches. Bass Strait, south-eastern Australia, is a key region for seabirds, with little penguins Eudyptula minor, short-
