That is true of a lot of the old trees in lkwd. The big old pin oaks and red oaks too. A lot of these are mature and stressed.
Some people don't realize the inside of the tree (the heartwood) is dead. It's only purpose is providing strength. The outside layers of the tree (cambium) is the living part. A lot of these old trees get ants, bugs, parasites, fungus and so on attacking the heartwood. They lose their strength/structure then start to drop limbs and/or fall.
A lot of these trees look perfectly healthy but are hollow in their trunk or limbs. If you have any of these big old trees, it is worth the money to have an arborist check them out every few years. Have a true arborist check it out, not Big Bubba's tree and lawn service....
In addition to what Jim said the other big problem with the silver maples is their
root system is shallow. They blow over easily.
If you have one of these big beauties in your back yard, and it is a typical postage stamp size lot with lots of ugly power, cable, phone lines strung all over, and has limited or zero access for machinery (I just described about every back yard in lkwd!) you will easily pay many thousands of dollars to have one of those trees taken down and out.
It's worth to have an arborist check it out.
