Linking seed dispersal to cache protection strategies (2011, background): “The causes of food-caching behaviour have received a great deal of attention from the perspective of animal cognition (e.g. Heinrich & Pepper 1998; Brotons 2000; Bugnyar & Kotrschal 2002; Emery, Dally & Clayton 2004; Dally, Clayton & Emery 2006; Hopewell & Leaver 2008; Pfuhl et al. 2009).”
A case of quick problem solving in birds: string pulling in keas, Nestor notabilis (2006, methodology): “…neither extensive tool use and manufacturing, as in New Caledonian crows, Corvus moneduloides (Hunt 1996), nor food caching and feeding in the vicinity of dangerous predators, as in ravens (Heinrich 1999; Bugnyar & Kotrschal 2002), are the evolutionary recipe for advanced intelligence in birds.”
Cache protection strategies by western scrub-jays, Aphelocoma californica: implications for social cognition (2005, background): “The risk of cache theft is particularly high in corvids, where conspecifics rely on observational spatial memory to pilfer, with a high level of accuracy, caches they have observed others make (Bednekoff & Balda 1996a, b; Clayton et al. 2001; Bugnyar & Kotrschal 2002).”
Elephant cognition in primate perspective (2009, background): “the highly social non-human primates have been the focus of intense interest, and research in comparative cognition has recently expanded to other large-brained and often social taxa, such as corvids (Bugnyar, 2002; Bugnyar & Heinrich, 2005; Clayton & Dickinson, 1998; Emery & Clayton, 2001, 2004), c”
Food stealing in birds: brain or brawn? (2007, background): “…corvids, reviewed in Dally et al. 2006) and kleptoparasitic tactics (e.g. ravens act inconspicuously while watching conspecifics caching food, Bugnyar & Kotrschal 2002; pigs follow and displace knowledgeable subordinates, Held et al. 2000; baboons use a conspecific in displacing a competitor…”
Testing Problem Solving in Ravens: String-Pulling to Reach Food (2005, background): “Raven’s life-style as crowd-foragers at carcasses pits them into constant interactions amongst themselves (Heinrich & Marzluff 1991; Bugnyar & Kotrschal 2002) and with dangerous predators such as wolves Canis lupus (Stahler et al. 2002; Vucetich et al. 2004).”
The behaviour and evolution of cache protection and pilferage (2006, methodology): “Indeed, an experiment by Bugnyar & Kotrschal (2002) found that ravens were able to use observational memory only when short time periods had elapsed between the caching and pilfering events.”
Social cognition by food-caching corvids. The western scrub-jay as a natural psychologist (2007, background): “Bugnyar & Kotrschal (2002) suggested that the capacity for observational spatial memory in corvids represented the catalyst for an ‘evolutionary arms race’ between cachers and pilferers, such that pilferers should develop methods for observing cachers as unobtrusively as possible, and cachers…”
Comparing the Complex Cognition of Birds and Primates (2004, background): “Bugnyar and Kotrschal (2002) have suggested that caching and raiding ravens may present an example of tactical deception through an attempt to manipulate another's attention, either to prevent opponents from gaining opportunities for stealing (see earlier section on social learning), or to gain…”
