Falling branches

I have a 30 foot (10 M) Ginko Tree that has suddenly
started to drop (in early July) the ends of its
branches. The falling branches are 1 to 1.5 feet (24
to 40 cm) in length. Four to five branches drop each
day. The leaves on falling branches seem to be
healthy. The point of the break is clean as if
pruned.
Other information: We have experienced over the
recent weeks 4 inches of rain. We have had below
average rainfall in the Spring and cooler than normal
temperatures. Japanese Beetles are infesting plants
in the area, but are not seen on the Ginko. For the
past three years the bottom three feet of the trunk
has had a loose wrap of copper window screen to
protect the trunk (bark)from domestic cats that prefer
to use the Ginko trunk as a claw post.

Could it be the twig pruner that causes this. There's an article about it on the website:

Copper is very toxic for plants. Get it away from your trees.

It is possible that the heavy rain has made the branches overweighed so wind or animals can easily snap them off. Some animals will actively break branches for nesting material.

I believe that the 7/22 comment has figured it out. I have discovered a new/ fresh squirrel nest in my tree. Branches seem to have stopped falling.
I have taken the copper screen away.
Thank you for your thoughts,

One of my females closest to the house has drooping branches this year due to the weight of the great number of fruits being produced. One 3 inch diameter X 15 foot branch broke off during a storm with high winds when the weight of hundreds of fruits pulled it down.
