Variation in foraging activity influences area-restricted search behaviour by bottlenose dolphins

Royal Society Open Science, 2023
Area-restricted search (ARS) behaviour is commonly used to characterize spatio-temporal variation in foraging activity of predators, but evidence of the drivers underlying this behaviour in marine systems is sparse. Advances in underwater sound recording

What currency do bumble bees maximize? [PDF]

PLoS ONE, 2010
In modelling bumble bee foraging, net rate of energetic intake has been suggested as the appropriate currency. The foraging behaviour of honey bees is better predicted by using efficiency, the ratio of energetic gain to expenditure, as the currency.

Geographical, temporal and individual factors influencing foraging behaviour and consistency in Australasian gannets [PDF]

Royal Society Open Science, 2020
Foraging is a behaviour that can be influenced by multiple factors and is highly plastic. Recent studies have shown consistency in individual foraging behaviour has serious ecological and evolutionary implications within species and populations.

Linking foraging and breeding strategies in tropical seabirds

Journal of Avian Biology, 2021
The archetypal foraging behaviour of tropical seabirds is generally accepted to differ from that of their temperate and polar breeding counterparts, with the former exhibiting less predictable foraging behaviour associated with the less predictable prey ...

Effects of Personality Traits on the Food-Scratching Behaviour and Food Intake of Japanese Quail (Coturnix japonica)

Animals, 2021
Overall foraging success and ultimate fitness of an individual animal is highly dependent on their food-searching strategies, which are the focus of foraging theory.

Inter-individual differences in foraging tactics of a colonial raptor: consistency, weather effects, and fitness correlates

Movement Ecology, 2020
Background Consistent inter-individual differences in behavioural phenotypes may entail differences in energy efficiency and expenditure, with different fitness payoffs. In colonial-breeding species, inter-individual differences in foraging behaviour may

Combined Use of GPS and Accelerometry Reveals Fine Scale Three-Dimensional Foraging Behaviour in the Short-Tailed Shearwater. [PDF]

PLoS ONE, 2015
Determining the foraging behaviour of free-ranging marine animals is fundamental for assessing their habitat use and how they may respond to changes in the environment. However, despite recent advances in bio-logging technology, collecting information on

Morphometric comparisons and novel observations of diurnal and low-light-foraging bees [PDF]

Journal of Hymenoptera Research, 2020
Low-light adapted bees are substantially understudied components of the bee fauna, particularly in Australia. Whilst several species in Australia are thought to be adapted to low-light conditions, explicit records of these taxa actually foraging at ...

Foraging currencies, metabolism and behavioural routines [PDF]

Journal of Animal Ecology, 2013
SummaryA fundamental issue in foraging theory is whether it is possible to find a simple currency that characterizes foraging behaviour. If such a currency exists, then it is tempting to argue that the selective forces that have shaped the evolution of foraging behaviour have been understood.We review previous work on currencies for the foraging ...

Foraging behaviour and diet of the guanay cormorant [PDF]

South African Journal of Marine Science, 1999
Maximum dive depths, timing and duration of foraging trips and diet of the guanay cormorant Phalacrocorax bougainvillii were investigated in January/February 1995 and February 1996 at the headland of Punta San Juan, Peru. Results from 27 birds engaged in chick rearing showed that the mean maximum dive depth was 33.9 ± 2.6 m, with a deepest dive of 74 m.
