Feathers have many uses. They insulate birds from water and cold temperatures. Individual feathers in wings and tail control flight. Color patterns serve as camouflage against predators. As with fish, the top and bottom colors are sometimes different to provide camouflage during flight. The colors of feathers are important in selection of mating pairs. Down feathers lack the tiny hooks that attach feathers one to another and thus are fluffy, allowing the down to trap much air and provide excellent insulation. In some birds, small particles break off continuously from the feathers, producing a powder that sifts through the feathers and acts as a waterproofing agent and feather conditioner.
