Color Change in Yellow Popular Leaf.........The first of the yellow popular leaves are beginning to color and fall. Southeastern Indiana has had a wet spring and summer. Why do specific leaves fall before others? Have read a lot about coloration of leaves, still don't fully understand. All I know, people travel many miles to watch them and it seems to make them happier. Macrograph shows the color interfaces within the leaf. Empirical observation indicates the round darker brown area may be the result of an injury. Things have no color, only reflect specific wavelengths of light, that we see as color. I love the fall.

Two Whitetail bucks at salt pit.....Don't see these guys a lot, about once every 7-8 days , even on the remote camera. Shot this on video, still framed it. They are still in the stage of being nice to each other, however the one standing has a get out of my way look in his eye. Not long after ,he took over the main position at the salt block. They circled each other a lot. They are in good shape for this time of year. Salt pit is 90 yards from the upper deck.
Macro graph of Blue Jay feather.......The pigment in Blue Jay feathers is melanin, which is brown. The blue color is caused by scattered light through modified cells on the surface of feather barbs (CORNELL LAB of ORNITHOLOGY , publication ). The WISCONSIN Natural Resources magazine indicates the MIGRATORY BIRD TREATY ACT makes it illegal to possess native bird feathers without a permit, except for game birds. Anyway, it is amazing to me the structure of feathers. PS... I return all feathers to nature
