Unlike other waterbirds, the feathers of the African Darter do not contain oil to keep it waterproof. Because of this, the bird is less buoyant which enhances its diving capabilities.
After diving for fish, the feathers can become waterlogged. In order to fly and maintain heat insulation it needs to dry its feathers.

Our Double-crested Cormorants have the same problem. It's wild to see them standing on rocks above the water with shiny black wings spread out like Dracula's cape.
