Energetic consequences of prey type in little penguins (Eudyptula minor)
Royal Society Open Science, 2023 Investigation of foraging decisions can help understand how animals efficiently gather and exploit food. Prey chase and handling times are important aspects of foraging efficiency, influencing the net energy gain derived from a prey item.

Confocal and Electron Microscopic Structure of the Cornea from Three Species of Penguin
Vision, 2023 Corneal confocal microscopy has not previously been performed in penguins, despite recognition of its unusually flat shape. To identify features that the penguin shares with other birds and or mammals and those specific to penguins, we undertook confocal

Animals, 2020 Studies on the effects of visitors on zoo animals have shown mixed findings and as a result, the manner in which visitors affect zoo animals remains unclear for many species, including a rarely studied taxa such as penguins.

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.

Fossil plotopterid seabirds from the Eo-Oligocene of the Olympic Peninsula (Washington State, USA): descriptions and functional morphology. [PDF]
PLoS ONE, 2011 The plotopterids (Aves, Plotopteridae) were a group of extinct wing-propelled marine birds that are known from Paleogene-aged sediments (Eocene to Miocene), mostly around the Pacific Rim (especially Japan and the northwest coast of North America).

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 ...

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

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-
