Function and flexibility of object exploration in kea and New Caledonian crows [PDF]
Royal Society Open Science, 2017 A range of non-human animals frequently manipulate and explore objects in their environment, which may enable them to learn about physical properties and potentially form more abstract concepts of properties such as weight and rigidity.

Waste Disposal Sites as All-You-Can Eat Buffets for Carrion Crows (Corvus corone)
Animals, 2019 In cities and densely populated areas, several corvid species are considered nuisance animals. In Austria, particularly carrion (Corvus corone) and hooded crows (C. cornix) are regarded as pests by the general public that frequently cause damage to crops,

Mortality associated with avian reovirus infection in a free-living magpie (Pica pica) in Great Britain [PDF]
, 2015 Avian reoviruses (ARVs) cause a range of disease presentations in domestic, captive and free-living bird species. ARVs have been reported as a cause of significant disease and mortality in free-living corvid species in North America and continental ...

Susceptibility of Carrion Crows to Experimental Infection with Lineage 1 and 2 West Nile Viruses
Emerging Infectious Diseases, 2015 West Nile virus (WNV) outbreaks in North America have been characterized by substantial die-offs of American crows (Corvus brachyrhynchos). In contrast, a low incidence of bird deaths has been observed during WNV epidemic activity in Europe.

Sex-specific effects of cooperative breeding and colonial nesting on prosociality in corvids
eLife, 2020 The investigation of prosocial behavior is of particular interest from an evolutionary perspective. Comparisons of prosociality across non-human animal species have, however, so far largely focused on primates, and their interpretation is hampered by the
