Every day, there are acrobatic extravaganzas going on above our heads in the form of squirrel parkour. This study reveals how decision-making & learning capabilities complement the biomechanical adaptations that enable these feats: SquirrelAppreciationDay
Every day, there are acrobatic extravaganzas going on above our heads. Squirrels navigate remarkably complex and unpredictable environments as they leap from branch to branch, and mistakes can be fatal. These feats require a complex combination of evolved biomechanical adaptations and learned behaviors. Hunt. characterized the integration of these features in a series of experiments with free-living fox squirrels .
Their success at making split-second, potentially life-threatening decisions of biomechanical capability depends on their skillful use of acrobatic maneuvers and learning from past efforts. Here, we found that free-ranging fox squirrels leaping across unfamiliar, simulated branches decided where to launch by balancing a trade-off between gap distance and branch-bending compliance. Squirrels quickly learned to modify impulse generation upon repeated leaps from unfamiliar, compliant beams.
