Birds in the bin It is by now well accepted that humans are not the only animal to have complex culture, and we have also found that ecological novelty can lead to cultural innovation. Klump et al. documented the emergence of an evolving set of behaviors in response to human-generated resources, specifically garbage bins, in sulphur-crested cockatoos. This finding both documents the existence and spread of complex foraging culture among parrots, a lineage known for high-level cognitive function… 

Social network analysis reveals context-dependent kin relationships in wild sulphur-crested cockatoos, Cacatua galerita

A preference to associate with kin facilitates inclusive fitness benefits, and increased tolerance or cooperation between kin may be an added benefit of group living. Many species exhibit preferred

Vultures as an overlooked model in cognitive ecology.

It is concluded that vultures may provide fresh insight into the authors' knowledge of the ecology and evolution of cognition, with evidence for a variety of innovative foraging behaviors, scrounging tactics, collective problem-solving abilities and tool-use, skills that are considered indicative of enhanced cognition.

Cultural diffusion dynamics depend on behavioural production rules

A generative model is presented that integrates transmission and production in order to explore how variation in either might shape cultural diffusion dynamics, and clarifies the distinction between acquisition and usage to illuminate often-overlooked theoretical differences between social learning and social influence.

The seminal book The Neolithic transition and the genetics of populations in Europe by Ammerman and Cavalli-Sforza (1984) contains the analysis of archaeological data that led to the result that the

Modelling how cleaner fish approach an ephemeral reward task demonstrates a role for ecologically tuned chunking in the evolution of advanced cognition

It is shown that chaining is the minimal requirement for solving the ephemeral reward task in its common simplified laboratory format, and the fine-tuning of this ability may be the major target of selection during the evolution of advanced associative learning.

Effects of early-life experience on innovation and problem-solving in captive coyotes

Early-life experience often shapes behaviors like innovation and exploration. These behaviors are important to animals encountering novel food resources in diverse habitats, such as mesocarnivores in

Social learning mechanisms shape transmission pathways through replicate great tit social networks

Comparing four different learning mechanisms, a simulated behavioural spread on replicate empirical social networks of wild great tits and explored the relationship between individual sociality and the order of acquisition of seeded behaviours reveal that, for learning rules dependent on the sum and strength of social connections to informed individuals, social centrality was strongly related to the orders of acquisition.
