Matt’s ongoing collaboration with Patrick-Jean Guay (Victoria University) and Mike Weston (Deakin) looking at predictors of flight initiation distances continues with a paper that examines whether the size of individual brain components is linked to the propensity to be flighty. We find little evidence that this is the case, contrasting with another recent paper in J. Evol. Biol by Erritzoe and Moller that found just that. We speculate a bit about why we’ve got different results. C’est la vie.
