These are milk weed pods releasing their seeds to the wind. These are not the tufts of truffula trees. Milk weed grows wild in fence rows and fallow fields or along roads such as this. I walked along the Big Spring this morning and saw a few birds but they were way smarter than me, I didn't get pictures of most. The cardinals, the kingfisher, the heron and the woodpecker all avoided the zoom lens. A pleasant, but brisk, walk regardless.
