Clark's Grebe - Lynda Goff Photography

#62. Young juvenile nestled under wing of adult Clark's Grebe. The young chicks do not have a developed oil gland and therefore are not "waterproof" and are subject to chilling in cold water. The adult waterproofs its feathers and that of the chick by rubbing oil from the gland on its head onto both chick and their own feathers.
