	Title	Stimulus enhancement in greylag geese: socially mediated learning of an operant task			Type	Journal Article
	Year	2000	Publication	Animal Behaviour	Abbreviated Journal
	Volume	59	Issue	6	Pages	1119-1125
	Keywords
	Abstract	We recently observed the spreading of a novel tradition in a flock of semiferal greylag geese, Anser anser: an increasing number of individuals began to bite and chew the stems of butterbur, Petasites hybridus. Because this behaviour spread particularly fast within families, social learning seemed to be involved. We therefore designed an experiment with hand-reared goslings, which were socially imprinted on humans, to investigate whether and how the observation of an experienced tutor affects the acquisition of a novel skill. Goslings had to open the gliding lid of a box to get at a food reward. To each of seven hand-reared observers a human tutor demonstrated where and how to open the lid, whereas seven controls remained untutored. All observers learned to perform the task but only one of the controls succeeded. The observers explored more often at the position shown by the tutor than elsewhere and seemingly learned by trial and error. In contrast, control birds explored primarily at positions that did not allow them to open the box. These results indicate that in greylag goslings the observation of an experienced model facilitates the learning of an operant task. We conclude that stimulus enhancement followed by operant conditioning were the mechanisms involved, which may have accounted for the fast spread of the stem-chewing tradition between family members.

	Title	Exchangeable producer and scrounger roles in a captive flock of feral pigeons: a case for the skill pool effect			Type	Journal Article
	Year	1986	Publication	Animal Behaviour	Abbreviated Journal	Anim. Behav.
	Volume	34	Issue	3	Pages	797-803
	Keywords
	Abstract	We investigated the foraging producer-scrounger system of a captive flock of feral pigeons (Columba livia) by monitoring the number of food patches each individual produced. In one experiment, three different patch types were tested on the whole flock while, in a second, flock composition was varied for one patch type. In all cases we found non-uniform distributions of the number of patches produced per individual, which suggests the existence of producer and scrounger roles. This result could not be explained by either dominance or variability in individual learning ability. Individuals switched roles in response to changes both in food patch type and flock composition. These results are discussed in light of the skill pool hypothesis, which suggests that, in a group, different foraging specialists will profit by parasitizing each other's food discoveries.

	Title	Social cognition			Type	Journal Article
	Year	2015	Publication	Animal Behaviour	Abbreviated Journal
	Volume	103	Issue		Pages	191-202
	Keywords	evolution; fitness; future research; personality; selective pressure; skill; social cognition
	Abstract	The social intelligence hypothesis argues that competition and cooperation among individuals have shaped the evolution of cognition in animals. What do we mean by social cognition? Here we suggest that the building blocks of social cognition are a suite of skills, ordered roughly according to the cognitive demands they place upon individuals. These skills allow an animal to recognize others by various means; to recognize and remember other animals' relationships; and, perhaps, to attribute mental states to them. Some skills are elementary and virtually ubiquitous in the animal kingdom; others are more limited in their taxonomic distribution. We treat these skills as the targets of selection, and assume that more complex levels of social cognition evolve only when simpler methods are inadequate. As a result, more complex levels of social cognition indicate greater selective pressures in the past. The presence of each skill can be tested directly through field observations and experiments. In addition, the same methods that have been used to compare social cognition across species can also be used to measure individual differences within species and to test the hypothesis that individual differences in social cognition are linked to differences in reproductive success.

	Title	Neophilia, innovation and social learning: a study of intergeneric differences in callitrichid monkeys			Type	Journal Article
	Year	2003	Publication	Animal Behaviour	Abbreviated Journal	Anim. Behav.
	Volume	65	Issue	3	Pages	559-571
	Keywords
	Abstract	In a comparative study of neophilia, innovation and social attentiveness we exposed individuals in seven callitrichid species, from three genera, to novel extractive foraging tasks. The results revealed consistently shorter response latencies, higher levels of successful and unsuccessful manipulation, and greater attentiveness to the task and to conspecifics inLeontopithecus (lion tamarins) than in both Saguinus (tamarins) and Callithrix (marmosets). This is consistent with the hypothesis that species dependent upon manipulative and explorative foraging tend to be less neophobic and more innovative than other species. Furthermore, Callithrix appeared to be less neophobic than Saguinus; ifCallithrix is regarded as the greater specialist, this result is inconsistent with the hypothesis that neophobia is associated with foraging specialization. We consider the relevance of our findings to taxonomic relationships, and to technical and Machiavellian intelligence hypotheses and discuss the implications for captive breeding and reintroduction strategies.Copyright 2003 Published by Elsevier Science Ltd on behalf of The Association for the Study of Animal Behaviour.

	Title	The origin and spread of innovations in starlings			Type	Journal Article
	Year	2008	Publication	Animal Behaviour	Abbreviated Journal	Anim. Behav.
	Volume	75	Issue	4	Pages	1509-1518
	Keywords	diffusion dynamics; dominance; foraging; group; innovation; neophobia; social learning; social network; starling; Sturnus vulgaris
	Abstract	There are numerous reports of novel learned behaviour patterns in animal populations, yet the factors influencing the invention and spread of these innovations remain poorly understood. Here we investigated to what extent the pattern of spread of innovations in captive groups of starlings, Sturnus vulgaris, could be predicted by knowledge of individual and social group variables, including association patterns, social rank orders, measures of neophobia and asocial learning performance. We presented small groups of starlings with a series of novel extractive foraging tasks and recorded the latency for each bird to contact and solve each task, as well as the orders of contacting and solving. We then explored which variables best predicted the observed diffusion patterns. Object neophobia and social rank measures characterized who was the first of the group to contact the novel foraging tasks, and the subsequent spread of contacting tasks was associated with latency to feed in a novel environment. Asocial learning performance, measured in isolation, predicted who was the first solver of the novel foraging tasks in each group. Association patterns did not predict the spread of solving. Contact latency and solving duration were negatively correlated, consistent with social learning underlying the spread of solving. Our findings indicate that we can improve our understanding of the diffusion dynamics of innovations in animal groups by investigating group-dependent and individual variables in combination. We introduce novel methods for exploring predictors of the origin and spread of behavioural innovations that could be widely applied.

	Title	Ranging patterns in white rhinoceros, Ceratotherium simum simum: implications for mating strategies			Type	Journal Article
	Year	2007	Publication	Animal Behaviour	Abbreviated Journal	Appl. Anim. Behav. Sci.
	Volume	74	Issue	2	Pages	349-356
	Keywords	Ceratotherium simum simum; foraging; habitat choice; home range use; mate choice; mating systems; ranging pattern; resource distribution; white rhinoceros
	Abstract	How animals use space has important consequences for feeding ecology, social organization, mating strategies and conservation management. In white rhinoceros, female home ranges are much larger than male territories, suggesting that movement patterns are influenced by factors other than resource distribution. In this study we placed radiotransmitters on 15 female white rhinoceros, recording 1758 locations and collecting behavioural data during 1671 observation sessions, making this the largest data set of its kind in this species. We investigated how habitat variables and male territories influenced female movement and reproductive behaviour. Female home ranges were approximately 20 km2 and core areas were 5 km2, with male territories roughly the same size as female core areas. Female range size did not vary with season, but the pattern of space use did vary. Females used grassland habitat preferentially, utilizing these areas significantly more than expected based on availability. Findings relevant to the mating strategy include: (1) the amount of grassland in a male's territory predicted female use of the territory; (2) the time that a female spent in a male's territory was a significant predictor of reproductive activity with the male, indicating that females probably mate with the most familiar male; and (3) the temporal pattern of female space use suggests that females did not increase mate sampling behaviour nor did they become more choosy about which males they visited when reproductively active. These findings suggest that males may maximize reproductive success by defending areas containing more grassland habitat.

	Title	Directed movement and orientation across a large natural landscape by zebras, Equus burchelli antiquorum			Type	Journal Article
	Year	2008	Publication	Animal Behaviour	Abbreviated Journal	Anim. Behav.
	Volume	76	Issue	2	Pages	277-285
	Keywords	correlated random walk; directed movement; Equus burchelli antiquorum; Gps; movement path; orientation; spatial memory; spatial scale; zebra
	Abstract	We investigated how plains zebras moved across a large natural landscape by analysing the movement paths of nine zebra mares foraging out from spatially confined waterholes during the dry season in the Makgadikgadi Pans National Park, Botswana. Since it was essential to investigate directed movement over a range of spatial scales to determine the correct movement behaviour and strategy, we used Nams's scaling test for oriented movement. Zebras followed directed movement paths in the lower to medium spatial scales (10 m–3.7 km) and above their visual, and possibly olfactory, range. The spatial scale of directed movement suggests that zebras had a well-defined spatial awareness and cognitive ability. Seven zebras used directed movement paths, but the remaining two followed paths not significantly different to a correlated random walk (CRW). At large spatial scales (>3 km) no distinct movement pattern could be identified and paths could not be distinguished from a CRW. Foraging strategy affected the extent of directed movement: zebras with a confined dispersion of grazing patches around the central place directed their movements over a longer distance. Zebras may extend the distance at which they can direct their movement after improving their knowledge of the local environment.

	Title	Social learning of foraging sites and escape routes in wild Trinidadian guppies			Type	Journal Article
	Year	2003	Publication	Animal Behaviour	Abbreviated Journal	Anim. Behav.
	Volume	66	Issue	4	Pages	729-739
	Keywords
	Abstract	We describe two field experiments with wild guppies, Poecilia reticulata, in Trinidad that demonstrated that guppies can acquire foraging and predator escape-response information from conspecifics. In the foraging experiment, subjects were presented with two distinctly marked feeders in their home rivers. One feeder contained a conspecific shoal in a transparent container. Guppies preferred to enter the feeder containing this artificial shoal over the other feeder. In a test phase, the artificial shoal was removed and the feeders replaced at the testing site after a 5-min delay. More guppies entered the feeder that had contained the artificial shoal over the other feeder, a difference that can be explained only by the fish learning the characteristics or location of the feeder during the training phase. We suggest that subjects acquired a foraging patch preference through a propensity to approach feeding conspecifics, a local enhancement process. In the predator escape-response experiment, naive 'observer' guppies could avoid an approaching trawl net by escaping through either a hole to which 'demonstrator' guppies had been trained or through an alternative hole. When the demonstrators were present, the naive observers escaped more often and more rapidly by the demonstrated route than the alternative route. When the demonstrators were removed, observers maintained a route preference according to the training of their demonstrators, which suggests that the observers had learned an escape route through following or observing their more knowledgeable conspecifics. Thus, both experiments reveal that guppies can socially learn in the wild. Copyright 2003 Published by Elsevier Ltd on behalf of The Association for the Study of Animal Behaviour.

	Title	Flexible spatial organization of urban foxes, Vulpes vulpes, before and during an outbreak of sarcoptic mange			Type	Journal Article
	Year	2000	Publication	Animal Behaviour	Abbreviated Journal	Anim. Behav.
	Volume	59	Issue	1	Pages	127-146
	Keywords
	Abstract	The social and spatial organization of urban fox groups prior to and during an outbreak of sarcoptic mange was compared with predictions derived from the resource dispersion hypothesis (RDH). We investigated the availability of three key resources. Neither daytime rest sites nor breeding sites appeared to be limited in availability. The availability of food deliberately supplied by local householders was examined by questionnaire surveys. The daily and weekly amount of food supplied was greatly in excess of the minimum requirements of a pair of foxes, but was consistent between territories. The availability of this food source increased markedly as a result of more people feeding the foxes. In agreement with the RDH, group size prior to the outbreak of mange increased from 2.25 animals (N=4) to 6.57 animals (N=7). Before the outbreak of mange, two territories were divided. Increased scavenge availability on smaller territories may have promoted these changes. Excluding these spatial changes, territories were very stable between years. After the outbreak of mange, group size declined as a direct result of mange-induced mortality. Surviving animals increased their ranges only after neighbouring groups had died out. Ranges did not increase in size in response to a decline in food availability. Nor were the increases in range size associated with the relinquishment of parts of the existing territory. These postmange changes are contrary to the RDH. Three factors may have promoted these changes: the elimination of interstitial space, the forced dispersal of young or future division of the territory.

	Title	The use of visual media as a tool for investigating animal behaviour			Type	Journal Article
	Year	2013	Publication	Animal Behaviour	Abbreviated Journal
	Volume	85	Issue	3	Pages	525-536
	Keywords	citizen science; crowdsourcing; internet; online resource; opportunistic observation; 'people power'; playback study; preliminary testing; YouTube
	Abstract	In this essay we outline how video-related technology can be used as a tool for studying animal behaviour. We review particular aspects of novel, innovative animal behaviour uploaded by the general public via video-based media on the internet (using YouTube as a specific example). The behaviour of animals, particularly the play behaviour focused on here, is viewed by huge audiences. In this essay we focused on three different kinds of media clips: (1) interspecies play between dogs and a range of other species; (2) object play in horses; and (3) animal responses to stimuli presented on iPads, iPods and iPhones. We argue that the use of video is a good means of capturing uncommon or previously unknown behaviour, providing evidence that these behaviours occur. Furthermore, some of the behaviours featured on YouTube provide valuable insights for future directions in animal behaviour research. If we also take this opportunity to convey our knowledge to a public that seems to be fundamentally interested in animal behaviour, this is a good means of bridging the gap between knowledge among an academic few and the general public.
