Autumn colours

The view from here

I've noticed the trees changing colour for a while now but the street tree in front of our house is always late to go. This morning I looked out the window & it seemed to have changed to a vivid yellow overnight.

I find it odd that the trees on our street are so individual in their decisions when to change hues for the season. They're all the same type of tree (no idea what kind), about the same size & age on this side of the street, yet these two are now completely different colours.
