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.

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.

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
