Machine learning reveals cryptic dialects that explain mate choice in a songbird
Nature Communications, 2022 The authors show that captive populations of zebra finches, which have been kept in isolation for up to 100 generations, have diverged in song dialect. When individuals singing different dialects are mixed, mating is assortative for song dialect.

The benefits of swimming together
eLife, 2023 When a fish beats its tail, it produces vortices in the water that other fish could take advantage of to save energy while swimming.

Probabilistic models of individual and collective animal behavior [PDF]
, 2017 Recent developments in automated tracking allow uninterrupted, high-resolution recording of animal trajectories, sometimes coupled with the identification of stereotyped changes of body pose or other behaviors of interest.

Dynamical modeling of collective behavior from pigeon flight data: flock cohesion and dispersion [PDF]
, 2011 Several models of flocking have been promoted based on simulations with qualitatively naturalistic behavior. In this paper we provide the first direct application of computational modeling methods to infer flocking behavior from experimental field data ...

Vortex phase matching as a strategy for schooling in robots and in fish
Nature Communications, 2020 Whether and how fish might benefit from swimming in schools is an ongoing intriguing debate. Li et al. conduct experiments with biomimetic robots and also with real fish to reveal a new behavioural strategy by which followers can exploit the vortices ...

Group size and composition influence collective movement in a highly social terrestrial bird
eLife, 2020 A challenge of group-living is to maintain cohesion while navigating through heterogeneous landscapes. Larger groups benefit from information pooling, translating to greater ‘collective intelligence’, but face increased coordination challenges.

The performance of field sampling for parasite detection in a wild passerine
Ecology and Evolution, 2022 Parasites can impact the behavior of animals and alter the interplay with ecological factors in their environment. Studying the effects that parasites have on animals thus requires accurate estimates of infections in individuals.

Social modulation of individual preferences in cockroaches
iScience, 2021 Summary: In social species, decision-making is both influenced by, and in turn influences, the social context. This reciprocal feedback introduces coupling across scales, from the neural basis of sensing, to individual and collective decision-making ...
