Meeting Abstract 138-7  Monday, Jan. 7 15:00 – 15:15  Avian locomotion strategies during arboreal foraging CHIN, DD*; LENTINK, D; Stanford University; Stanford University ddchin@stanford.edu Arboreal birds frequently hop and fly among tree branches to search for food. In the process, they must maneuver around intervening leaves or branches that obstruct flight paths between reliable perches. To understand […]
