"In this review there are the informations of intraspecific oriented chemosignals, pheromones respectively, furthermore interspecific chemosignals and the chemical interactions with parasites are summarized. Intraspecific chemosignals are known in some seabirds, auklets, petrels and others secreted a distinctive scent closely associated with courtship and important in sexual selection. Individually distinctive odours allow them to identify their own nest and can have a significant role in social relationships. Substances considered as sex pheromones, diesters of 3-hydroxy fatty acids, produce females of mallard in their uropygial glands during the mating season. In many species of Charadriiformes during nesting monoester waxes are substituted with mixtures of less volatile diester waxes, worse detected by mammals searching nests. The tissues, mainly skin and feather of the New Guinean Passerines of the genus Pitohui and Ifrita contain the steroidal alkaloids from the batrachotoxin group probably as a"@en .
