This chapter discusses the physiology and behavioral responses of aquatic birds to chemical stimulants. It presents comparisons of aquatic versus terrestrial chemical sensations in aquatic birds. It focuses on avian olfaction, homing and foraging by olfactory cues, avian chemesthesis, and avian gustation. It also examines evolutionary changes in avian chemical senses using fossil records of basal ornithurines and extinct Pelecaniformes, and comparative analysis of extant species of Anseriformes, Pelecaniformes, Procellariformes, Gaviiformes, Sphenisciformes, Charadriiformes, and Podicipediformes.
