Does Body Mass Constrain Avian Wing Shape or Sternum Shape
Meeting Abstract 116-3 Sunday, Jan. 7 08:30 – 08:45 Does Body Mass Constrain Avian Wing Shape or Sternum Shape? BAUMGART, SL; Univ. of Chicago slbaumgart@uchicago.edu Two factors central to flight mechanics in birds are forces exerted by the flight muscles on the wing and wing shape that governs its aerodynamics. Wing shape has been linked to behavior, […]
