It is just amazing if you think about, how our world is filled with diversity. Be it diversity among us people, or amongst the animals, the trees also are so different, even in their ways to lose their leaves in autumn.
Some trees have lost almost every leave by now, and others are still green like in the summer.
Some trees turn slowly, all leaves at once, and others, like the birches, seems to lose their color in steps. Some of the leaves turn yellow, and others are still green, which gives the birch a funny colored look.
