Spatial consistency affects foraging effort in a benthic diving seabird, the Black‐faced Cormorant Open
For animals which exploit predictable food resources, greater foraging site fidelity has been hypothesized to lead to increased foraging efficiency. However, evidence for this in free‐ranging species is limited. In the present study, forag…

Identifying prey capture events of a free-ranging marine predator using bio-logger data and deep learning Open
Marine predators are integral to the functioning of marine ecosystems, and their consumption requirements should be integrated into ecosystem-based management policies. However, estimating prey consumption in diving marine predators requir…

Foraging behaviour and habitat use during chick-rearing in the Australian endemic black-faced cormorant (<i>Phalacrocorax fuscescens</i>) Open
Despite its wide distribution, relatively little is known of the foraging ecology and habitat use of the black-faced cormorant (Phalacrocorax fuscescens), an Australian endemic seabird. Such information is urgently required in view of the …

Determining energy expenditure in a large seabird using accelerometry Open
The trade off between energy gained and expended is the foundation of understanding how, why and when animals perform any activity. Based on the concept that animal movements have an energetic cost, accelerometry is increasingly being used…

Energetic consequences of prey type in little penguins ( <i>Eudyptula minor</i> ) Open
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. …

Pacific Gulls (Larus pacificus) as Potential Vectors of Coxiella burnetii in an Australian Fur Seal Breeding Colony Open
Recently, Coxiella burnetii has been described as a novel pathogen potentially contributing to decreased pup production in Australian fur seals (AusFS, Arctocephalus pusillus doriferus). Pacific gulls (PGs, Larus pacificus) are known to sc…

Quantity over quality? Prey-field characteristics influence the foraging decisions of little penguins ( <i>Eudyptula minor</i> ) Open
Quantifying prey characteristics is important for understanding the foraging behaviour of predators, which ultimately influence the structure and function of entire ecosystems. However, information available on prey is often at magnitudes …

Stage-Dependent Niche Segregation: Insights From a Multi-Dimensional Approach of Two Sympatric Sibling Seabirds Open
Niche theory predicts that to reduce competition for the same resource, sympatric ecologically similar species should exploit divergent niches and segregate in one or more dimensions. Seasonal variations in environmental conditions and ene…

Temporal and spatial isotopic variability of marine prey species in south-eastern Australia: Potential implications for predator diet studies Open
Stable isotope analyses, particularly of carbon ( δ 13 C) and nitrogen ( δ 15 N), are used to investigate ecological relationships among species. For marine predators, research has shown the main factors influencing their intra-specific an…

Fine-scale foraging movements and energetics in penguins Open
This research investigates the factors influencing foraging effort and efficiency in penguins. Using a combination of animal-borne video cameras, accelerometers, dive recorders and GPS, this study validated accelerometry as an accurate pre…

Influence of hunting strategy on foraging efficiency in Galapagos sea lions Open
The endangered Galapagos sea lion (GSL, Zalophus wollebaeki ) exhibits a range of foraging strategies utilising various dive types including benthic, epipelagic and mesopelagic dives. In the present study, potential prey captures (PPC), pr…

Validating accelerometry-derived proxies of energy expenditure using the doubly labelled water method in the smallest penguin species Open
Understanding energy use is central to understanding an animal's physiological and behavioural ecology. However, directly measuring energy expenditure in free-ranging animals is inherently difficult. The doubly labelled water (DLW) method …

Multi-predator assemblages, dive type, bathymetry and sex influence foraging success and efficiency in African penguins Open
Marine predators adapt their hunting techniques to locate and capture prey in response to their surrounding environment. However, little is known about how certain strategies influence foraging success and efficiency. Due to the miniaturis…

Inefficient trade-offs of visual and motor information during time-limited movements in childhood Open
Visuomotor abilities, such as crossing a busy road or intercepting a ball, continue to improve until late childhood - but what drives these improvements is unclear. We tested whether development of visuomotor skill in childhood might in pa…

Departure time influences foraging associations in little penguins Open
Recent studies have documented that little penguins (Eudyptula minor) associate at sea, displaying synchronised diving behaviour throughout a foraging trip. However, previous observations were limited to a single foraging trip where only a…
