Patricia, I've seen the behavior you describe with trees in my favorite trail-walking park during years with early cold weather. This maple has been behaving oddly for the past 18 months or so. In fall 2016 it was late to drop its leaves, though they finally did fall in a big burst about two weeks after my other maple dropped its last stragglers. This past spring both maples budded normally but the leaves grew slowly, maybe due to unusually cool May weather. (My lilies were late too.) This fall the other maple dumped its leaves a little late but they did come down. But with the pictured tree the leaves have been very stubborn, wind or cold or lack thereof. It's kinda comical driving down my street and seeing nothing but bare branches, then this weirdo. I'm hoping it's just confused rather than ill.
