Haibun-Haiku: Oak leaves changing colors

oak leaves are changing
their green if fading each day
a chill in the air

I noticed that the leaves on the neighbors oak tree have begun to change color. The green on some of the leaves are fading to yellow, while others are beginning to turn orange. This morning, when I went out to get the newspaper there was a chill in the air. I did not stay out very long, but I did get a change to look up and see the morning star.
