I would get a bb gun and put one in his head. I have had a major problem with them boogers eating my planted seeds. Ive lost hundreds of seeds an seedlings due to them. But i know your not worried about that. I dont think it will harm it, unless he breaks a branch. If the tree is not too big, you could just pick the seeds off.

I would be more worried in the spring, when squirrels will sometimes eat the new buds as they start to grow. Evidently they're packed with sugar at that time, and the squirrels need that since they're having their babies at that time of year. They can decimate a JM by eating all the buds off it. BB gun may be best option at that point!
