{"fact":"Rooks, known for probing deep into the ground for food, tend to escape for longer periods when starting further away from a potential predator, unlike hooded crows and jackdaws. This suggests a heightened wariness in rooks possibly due to their focused foraging style.","context":"An interesting side-result was that starting distance, i.e. the distance at which the observer started his approach, was in a positive relationship with escape duration for the rook but not for the other two species (Fig. A4). ... We do not know the exact reason for why only the rook increased escape duration when approached at a longer starting distance, but it could once again be related to wariness of the species","source":"Kunter Tätte; Anders Pape Møller; Raivo Mänd, Corvids exhibit dynamic risk assessment during escape, 10.1016/j.beproc.2019.104017","index":625}
