Oil And Feathers Don't Mix Either
Did you know that birds have their own wet suit? It's actually more like built-in waterproofing. This special kind of insulation helps them float on top of the water! It is made up of layers of feathers and connecting strands called barbs which protect the bird from the cold and help it stay dry. When a bird's feathers are coated with oil, the bird loses its waterproofing. Then, it is at risk of being exposed to cold temperatures. In addition, birds often get sick from breathing and swallowing the oil.
