Lice on Feathers (IMAGE)
Caption
Lice hide in tiny gaps inside feathers, called the interbarb space, to escape deadly beaks. If the lice are too big, the birds quickly snatch the up. But bigger female lice lay more eggs. Evolutionary winners occupy a sweet spot: They're small enough to hide, but big enough to outbreed their neighbors.
