TL;DR: The authors showed that ravens react differently to playbacks of dominance interactions that either confirm or violate the current rank hierarchy of members in their own social group and of ravens in a neighbouring group.

TL;DR: It is shown that ravens react differently to playbacks of dominance interactions that either confirm or violate the current rank hierarchy of members in their own social group and of ravens in a neighbouring group, suggesting thatRavens understand third-party relations and may deduce those not only via physical interactions but also by observation.

TL;DR: It is argued that the non-breeding period is key to understand raven social life and, to a larger extent, avian social life in general and the combination of the large-scale perspective and the individual- scale perspective allows to better capture the complete set of social challenges experienced by individuals throughout their life, ultimately resulting on a more comprehensive understanding of species’ social complexity.

TL;DR: This work examined the fission-fusion patterns of non-breeding ravens over years, investigating whether birds meet repeatedly either at the same or at different locations, and found a highly dynamic system in which individuals with long phases of temporary settlement had a high probability of meeting others.

TL;DR: Intriguingly, prosociality was most prominent from male to male, and less likely among all other sex-combinations, suggesting the presence of male-exclusive networks in science, and may be based on an evolutionary history promoting strong male bonds.
