I figured out how to fix the animation in the .blend file using blender 2.93.5 on a Mac:
(1) Load the blender file
(2) Select the bird mesh (click the bird)
(3) OPTION + P - on popup choose clear and keep transformation
(4) SHIFT and click the armature (the grey bones inside the bird)
(5) CTRL + P - on popup choose Armature deform With automatic weights
