The Presence and Behaviour of Birds at Two Prescribed Fires in Sweden. [PDF]
Ecol EvolShifting fire regimes pose immediate threats to animal conservation. Swedish birds appear to mostly ignore prescribed fire, and some species even continue to sing. Behavioural plasticity towards fire is poorly understood, but may prove to be an essential tool in animal conservation.

What if Eurasian jay Garrulus glandarius would larder acorns instead of scatter them?
IForest, 2018 Jays usually store acorns at separate sites, but in some cases a part of jay’s caches consists of more than one acorn. Storing acorns separately (scatter hoarding) or in clusters (larder hoarding) seems to be an important factor for further survival of ...

Passive environmental and group-level processes drive gut microbiome composition in a wild corvid [PDF]
Animal MicrobiomeBackground The gut microbiome is known from laboratory studies to be essential to host function and sociality, yet comparatively little is known about this association in wild animals.

Journal of Applied EcologyOur findings show that Eurasian jay dispersal activity depends on specific understorey structures when selecting caching microsites—particularly shrub cover and standing pines. These features could be directly shaped by management to promote assisted natural oak regeneration.

How Flexible is Tool Use in Eurasian Jays (Garrulus glandarius)? [PDF]
Animal Behavior and Cognition, 2020 Eurasian jays (Garrulus glandarius) do not habitually use tools, yet they can be trained to solve object-dropping tasks, i.e., to insert a tool into an apparatus to release a food reward.

Facing a Clever Predator Demands Clever Responses - Red-Backed Shrikes (Lanius collurio) vs. Eurasian Magpies (Pica pica). [PDF]
PLoS ONE, 2016 Red-backed shrikes (Lanius collurio) behave quite differently towards two common nest predators. While the European jay (Garrulus glandarius) is commonly attacked, in the presence of the Eurasian magpie (Pica pica), shrikes stay fully passive.
