This is the toucan that services the papaya tree. Enticed by the allure of sugar and survival, the toucan perches on the branch and dips down to dig a hole in the fruit, visible in this photo. This is the papaya tree that has lured not only the toucan but dozens of other species (including we human animals) into carrying its seeds and spreading its genes throughout the region. The seeds of the tree must be scattered far and wide, or they will fester in the shade of the parent plant. Each seed must find its own patch of sunlight, just as each toucan must seek its own sweetness. There is a perfection to this arrangement, the self-interest of each individual organism resulting in the unwitting cooperation of the entire interconnected ecosystem. What lessons lurk in each leaf?
