Tool-use and instrumental learning in the Eurasian jay (Garrulus glandarius)
Animal Cognition, 2011Recent research with Rooks has demonstrated impressive tool-using abilities in captivity despite this species' classification as a non-tool-user in the wild. Here, we explored whether another non-tool-using corvid, the Eurasian Jay, would be capable of similar feats and investigated the relative contributions of causal knowledge and instrumental ...

Piagetian object permanence and its development in Eurasian jays (Garrulus glandarius)
Animal Cognition, 2007Object permanence in Eurasian jays (Garrulus glandarius) was investigated using a complete version of the Uzgiris and Hunt scale 1. Nine hand-raised jays were studied, divided into two groups according to their different developmental stages (experiment 1, older jays: 2-3 months old, n = 4; experiment 2, younger jays: 15 days old, n = 5).

Pilfering Eurasian jays use visual and acoustic information to locate caches
Animal Cognition, 2014Pilfering corvids use observational spatial memory to accurately locate caches that they have seen another individual make. Accordingly, many corvid cache-protection strategies limit the transfer of visual information to potential thieves. Eurasian jays (Garrulus glandarius) employ strategies that reduce the amount of visual and auditory information ...

Exclusion in corvids: The performance of food-caching Eurasian jays (Garrulus glandarius).
Journal of Comparative Psychology, 2013Choice by exclusion involves selecting a rewarded stimulus by rejecting alternatives that are unlikely to be rewarded. It has been proposed that in corvids, exclusion is an adaptive specialization for caching that, together with object permanence and observational spatial memory, enhances a bird's ability to keep track of the contents of caches.

How the Eurasian Jay Expands its Color Palette by Optimizing Multiple Scattering
Advanced Optical Materials, 2022AbstractThe production of structural color in nature is still incompletely understood. Multiple scattering exerts critical effects on synthetic disordered systems, but its effects on structural colors in natural materials are not yet well known. Here, electron microscopy, optical modeling, and biomimicry are used to show that variation in the thickness

Circular replication associated protein (Rep)-encoding ssDNA (CRESS DNA) viruses have diverse genomic architecture and are widely distributed in different ecosystems. In this study we characterized the complete genomic sequence of a novel circovirus-like virus, Garrulus glandarius associated circular virus-1 (GgaCV-1).
