The foraging behaviour of granivorous birds: a mechanistic perspective. [PDF]

1. The functional response, i.e. the feeding rate as a function of prey density, links resource availability to population level demographic rates. The functional response is often central to behavioural-based population models that predict the effect ...

The importance of predator behaviour on risk to prey [PDF]

, 2008
Both predator and prey have evolved to maximise reproductive success by balancing food intake with risk. There has been a bias in predator-prey studies, where prey behaviour has been examined in detail, yet predators are assumed to follow simplistic ...

Attack strategies in birds of prey [PDF]

, 2016
Pursuit behaviours are vital in predator-prey interactions and in courtship for many flying animals. Existing research on target-directed flight behaviours in insects[1-9], birds[10-12] and bats[13] has aimed at identifying simple geometric rules ...

Molecular data support Bombus sonorus and Bombus pensylvanicus (Hymenoptera, Apidae) as distinct species [PDF]

Journal of Hymenoptera Research
Despite their distinctive banding patterns, setal coloration, and geographic ranges, the Sonoran bumble bee (Bombus sonorus Say, 1837) and the American bumble bee (Bombus pensylvanicus De Geer, 1773) are often treated as conspecific, with some ...

Using GPS and accelerometer data to precisely record egg laying, incubation and chick hatching of Cinereous Vultures (Aegypius monachus) in-situ [PDF]

Biodiversity Data Journal
The Cinereous Vulture (Aegypius monachus) is a near-threatened species, making detailed monitoring of its breeding behaviour crucial for effective conservation. Traditional methods are often invasive and logistically challenging.

Predation risk in relation to brain size in alternative prey of pygmy owls varies depending on the abundance of main prey

PLoS ONE, 2020
Large brains in prey may select for adoption of anti-predator behavior that facilitates escape. Prey species with relatively large brains have been shown to be less likely to fall prey to predators.

Economic aspects birds of prey usage as bird control operation

RUDN Journal of Ecology and Life Safety, 2019
Birds attracted to citys waste landfills represent a significant hazard and additional inconvenience to people. It is necessary to understand not only the reasons for which birds enter the given territory, but also the economic components of the scaring ...

The index of ornithological attractiveness of facilities for the processing and disposal of municipal solid waste

RUDN Journal of Ecology and Life Safety, 2019
In connection with the increase in the number of household facilities attractting birds and the widespread growth of synanthropic bird populations, the problem of ornithological safety is becoming more and more urgent. For effective scaring away of birds
