Shy puffin - Atlantic puffin (Fratercula arctica)

Preening is a very important activity, only second to feeding. During this process, the bird removes dirt, dust, and parasites from the feathers. Well maintained, they stay waterproof and provide perfect insulation. And as the puffin is a seabird that nests underground, there are a lot of things to do to keep the plumage in top shape.
