Happy #FlamingoFriday ! Preening is a natural behavior for our friends of the feathered variety. The individual strands, called barbules, that make up a feather can become unattached from one another. Like a zipper, they can be “zipped” back together and made whole again. The preening process also allows for the application of naturally produced oils to keep the feathers to keep them healthy and waterproof! #flamingo #palmbeachzoo #westpalmbeach | Palm Beach Zoo
