Functional morphology and integration of corvid skulls - a 3D geometric morphometric approach [PDF]
, 2009 BACKGROUND: Sympatric corvid species have evolved differences in nesting, habitat choice, diet and foraging. Differences in the frequency with which corvid species use their repertoire of feeding techniques is expected to covary with bill-shape and with ...

“I am Wolf, I Rule!” - Attributing Intentions to Animals in Human-Wildlife Interactions
Frontiers in Conservation Science, 2022 Human interactions with potentially problematic wildlife spawn intense and polarized sentiments. This study investigates one contributing factor: People perceive wildlife as having intentions toward them, and consequently, they feel targeted by the ...

How task format affects cognitive performance:a memory test with two species of New World monkeys [PDF]
, 2016 In cognitive tests, animals are often given a choice between two options and obtain a reward if they choose correctly. We investigated whether task format affects subjects' performance in a physical cognition test.

A two-species stage-structured model for West Nile virus transmission [PDF]
, 2017 We develop a host–vector model of West Nile virus (WNV) transmission that incorporates multiple avian host species as well as host stage-structure (juvenile and adult stages), allowing for both species-specific and stage-specific biting rates of vectors ...

Captive jays exhibit reduced problem-solving performance compared to wild conspecifics [PDF]
Royal Society Open Science, 2019 Animal cognitive abilities are frequently quantified in strictly controlled settings, with laboratory-reared subjects. Results from these studies have merit for clarifying proximate mechanisms of performance and the potential upper limits of certain ...

Is caching the key to exclusion in corvids? The case of carrion crows (Corvus corone corone) [PDF]
, 2011 Recently, two corvid species, food-caching ravens and non-caching jackdaws, have been tested in an exclusion performance (EP) task. While the ravens chose by exclusion, the jackdaws did not. Thus, foraging behaviour may affect EP abilities.

International Journal of Osteoarchaeology, EarlyView.ABSTRACT The golden eagle (Aquila chrysaetos) nests in rock cavities where it accumulates prey bone remains during the breeding season. Because nests can be reoccupied from year to year, these faunal elements can form remarkable bone accumulations and, in the sub‐fossil record, be mixed with assemblages derived from human or other predator activities ...

Habitat selection and reproduction of red-backed shrikes (Lanius collurio) in relation to abundance of potential avian nest predators [PDF]
, 2010 Many studies of farmland bird species have related abundance of species to different habitat variables, whereas few studies have incorporated the effects of predation on habitat selection. However, it is generally assumed that prey species select habitat
