Rigging
With full controllers, postures and animations are easier to create, the features are as follows:
MandarinDuck_Female_Coverts_Rig_grp and MandarinDuck_Female_Remiges_Rig_grp are skeletons of feathers; MandarinDuck_Female_Body_Rig_grp is the main rigging that controls the model.
CTR_gravity controls the movement of the body, and it has 5 customized attributes:

1. head_IK_follow controls whether the head moves following it in IK mode;
   
2. neck_FK switches to FK control of neck;
   
3. neck_IK_IKSpline switches the control mode of the neck between IK and Spline IK;
   
4. neck_IK_Stretch controls the stretch limit of the neck in IK mode;
   
5. neck_follow controls whether the root of the neck moves following the body in IK or FK mode;
   
6. tongue_IKFK controls the switch of IK/FK of the tongue.
   IKFK_leg.L and IKFK_leg.R control the switch of IK/FK of the legs by the customized attribute IK_FK, and control the stretch limit of the legs in IK mode by IK_stretch.
   CTR_toe_action.L and CTR_toe_action.R control the extension and flexion of the feet.
   CTR_foldwing.L and CTR_foldwing.R control the folding of the wings by their Location.
   CTR_Fold_Rectrices folds tail feathers by the X-Location.
   Fine rigging makes it possible to control every feather, and fold, unfold and bend wings conveniently.
   And more...
   

Animations
Unlooped swimming animation at 30 fps, frame range 0-360

Features
A part of the feathers have two UVs for a better result.
To fix the intersection with body feathers, feathers on the neck apply Cloth, and the Cloth is baked to shape key.
MandarinDuck_Female_Feather_Head_Face is not controlled by the rigging because of Surface Deform modifier; Disable Surface Deform modifier, and enable Armature modifier to enable rigging control.
To get a nice effect, the settings below are required for such thick feathers:

1. Set Total under Light Paths to 12, or larger;
   
2. Set Transparency under Light Paths to 65 at least;
   
3. Set Transmission under Light Paths to 12 at least;
