Hi Dan,
• No constrain. The flap occurs in the beginning, and is not based on the Vibrate tag at all. If you like to have this working, define a Goal, and make it a child of the Vibrate Tag. Not sure if that works as you like to have it.
• No Dynamics, same here, all you get is the initial movement and then nothing. The first joint can’t put any force into the IK chain.
• Both, well…
The animated version:

Keep in mind that the Dynamics with the Inverse Kinematics do not work with the first joint at all in the IK chain. It is driven by the last one and so the Goal Null would be the one that needs to be moved, or the whole chain, i.e., the Parent Object. The Dynamic Tab contains some “curves” options, in those you can change along the chain the parameters of Position or Rotation Hold, which seems to be an essential part of a wing.
“Id like to check if I have this set up to me most efficient.” Well, that might be a discussion where I believe each artist might have his/her own take. My way of doing it, would be always determine by the first requirement, how much control do I have, then how much work is the set up, and how much time does it take to change things: for the rigging itself, or the animation.
The typical (things vary!) way would be, the rigging time is a single work, independent from the animation. The animation might be short or a very frequent work. There should be a good balance between the two. However, an animator should be able to focus purely on the motion and expression, not the rigging.
Having said that, a Pose Morph (joint-hierarchy) seems to be the way to go. So the wing has some predefined motions, and a single set of keyframes, while set to repeat after (multiple time) will allow for a nice and art directed result, without a constant calculation of the dynamics. IF a flock of birds is even wanted, that might add up. An alternative would the the Animation clip.
Again, if you have a mandatory use for dynamics, that would be a different idea, but I can’t see it, as a wing of a bird flaps, then glides, while the bird body moves up and down as well, it is not stable (summery of power).
All the best
