The tree is ablaze with vibrant fall colors and in the middle of it sits a dull black bird, a Common Grackle (Quiscalus quiscula), whose only touch of color is his yellow eyes. The juxtaposition of the contrasting elements, I believe, makes the image more interesting than either of them would have been separately.

Like the contrast that it creates with the background
Thanks. That contrast was the very factor that made me decide to post the photo.
I like the compostion with the grackle low and then the spray of fall colors around it,
Thanks. That was a choice I made after playing around with a number of different possibilities–there were leave on all sides.
