Social influences on delayed gratification in New Caledonian crows and Eurasian jays. [PDF]
PLoS One, 2023 Abstract Self-control underlies goal-directed behaviour in humans and other animals. Delayed gratification - a measure of self-control - requires the ability to tolerate a delay and/or invest more effort to obtain a reward of higher value over one of lower value, such as food or mates.

High prevalence of haemosporidian parasites in Eurasian jays. [PDF]
Parasitol Res, 2023 Abstract Avian haemosporidians are vector-borne parasites, infecting a great variety of birds. The order Passeriformes has the highest average infection probability; nevertheless, some common species of Passeriformes have been rather poorly studied. We investigated haemosporidians in one such species, the Eurasian

Eurasian jays (Garrulus glandarius) conceal caches from onlookers [PDF]
Animal Cognition, 2014 Animals that cache food risk having their stored food pilfered by conspecifics. Previous research has shown that a number of food-caching species of corvid use strategies that decrease the probability of conspecifics pilfering their caches. In this experiment, we investigated whether Eurasian jays (Garrulus glandarius) would choose between caching ...

Eurasian jays (Garrulus glandarius) show episodic-like memory through the incidental encoding of information. [PDF]
PLoS OneEpisodic memory describes the conscious reimagining of our memories and is often considered to be a uniquely human ability. As these phenomenological components are embedded within its definition, major issues arise when investigating the presence of episodic memory in non-human animals.

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.

Mirror-mediated string-pulling task in Eurasian jays (Garrulus glandarius) [PDF]
Animal Cognition, 2021 AbstractMirror tasks can be used to investigate whether animals can instrumentally use a mirror to solve problems and can understand the correspondence between reflections and the real objects they represent. Two bird species, a corvid (New Caledonian crow) and a parrot (African grey parrot), have demonstrated the ability to use mirrors instrumentally ...

Testing two competing hypotheses for Eurasian jays’ caching for the future [PDF]
Scientific Reports, 2021 Abstract Previous research reported that corvids preferentially cache food in a location where no food will be available or cache more of a specific food in a location where this food will not be available. Here, we consider possible explanations for these prospective caching behaviours and directly compare two competing hypotheses ...

Mirror stimulation in Eurasian jays ( Garrulus glandarius )
PeerJ, 2023 Mirror exposure elicits a wide range of behavioral responses, some of which have been considered as part of possible evidence of mirror self-recognition (MSR). These responses can range from social behaviors, indicating that an animal considers its own reflection as a conspecific, to mirror-guided and self-directed actions.

Investigating the flexibility of male Eurasian jays' food-sharing behavior
, 2020 Male Eurasian jays were previously reported to alter their food-sharing response in line with the specific satiety of their female partner. Here, we tested the flexibility of the same males’ food-sharing behavior by testing whether they can process information from contextual cues that predict the opposite pattern of food shared to that observed in ...
