Why do autumn trees of the same species change colour at different times?

I don’t mean differing tree types, but trees in the same woodland, of the same species, can be in completely different stages of shedding- how come? Why do they not all loose their leaves around the same time?

A tree at the top of a hill will get more light than a tree at the bottom of a hill. A tree that is exposed to the elements will get more cold than a tree that is less exposed. As the seasons shift these differences are exacerbated. Additionally every tree has slight differences within the same species.
