Morphological evolution of bird wings follows a mechanical sensitivity gradient determined by the aerodynamics of flapping flight

This study examines how mechanical sensitivity, driven by flapping flight aerodynamics, influences the evolutionary dynamics of bird wing morphology across 178 species.

How Turkey vultures tune their airspeed to environmental and behavioral factors

This study shows Turkey vultures adjust their airspeed with air density to optimize flight efficiency, using 3D videography across different elevations.

Three-dimensional actuation of hummingbird wings requires diverse effects from the primary flight muscles

This study develops a functional model of hummingbird musculoskeletal system to reveal how primary flight muscles generate three-dimensional wing actuation through diverse effects.

ThruTracker: Open-Source Software for 2-D and 3-D Animal Video Tracking

ThruTracker is an open-source software for 2-D and 3-D animal video tracking, tested on bats and birds with comparable accuracy to humans.

Compound-V formations in shorebird flocks

The paper identifies a consistent interaction rule in shorebird flocks that scales with wingspan and forms a compound-V structure, potentially enhancing aerodynamic efficiency.
