Colours of Autumn

Many thanks Dave, unusual colors I thought.

Sublimes couleurs automnales!!

Christiane is right: it is cherry, and those few leaves at the tip of bald twiggs can tell us, that it could be Prunus cerasus (sour cherry, tart cherry, or dwarf cherry).
And one more story is told by your beautiful image: those bays cut out at some of the leaves are not munched by caterpillars. In this very case, solitary bees (leafcutter bees) got the basic material for their nurseries here. Many of them are specialized on only one plant variety - so the owner of this cherry tree decides to cut it down, he will affect hundreds or thousands of solitary bees..

Well, and about your photo: I agree with all, what is written further up. ;-)

Thank you for the comprehensive and welcome comments Leon. they really are appreciated.
