Taxonomic Differences Between Birds And Mammals In Their Responses To Chemical Irritants, Russell Mason, Larry Clark, Pankaj Shah Jan 1992

Taxonomic Differences Between Birds And Mammals In Their Responses To Chemical Irritants, Russell Mason, Larry Clark, Pankaj Shah

Larry Clark

Ninety-five products are registered with the u.s. Environmental Pro­ tection Agency as bird damage control chemicals, but 38 (40%) are non­ lethal chemical repellents (Eschen and Schafer, 1986). Of these products, the active ingredients in 27 (71%) are methiocarb (a physiologic repellent that acts through food avoidance learning) or polybutene (a tactile repel­ lent). In general, chemical repellents are effective either because of aversive sensory effects (irritation), or because of post-ingestional ma­ laise (sickness). If the former, then chemicals are usually stimulants of trigeminal pain receptors (i.e., undifferentiated free nerve endings) in the nose, mouth, and eyes (Mason and Otis, …

A Model For Understanding The Evolution Of Mammalian Behavior, Raymond P. Coppinger, Charles Kay Smith Dec 1989

A Model For Understanding The Evolution Of Mammalian Behavior, Raymond P. Coppinger, Charles Kay Smith

Charles Kay Smith

Unlike reptiles, who are born with species-specific morphology and behavior that hardly changes as they grow into adults, mammals are born with a class-specific neonatal phase that renders the morphology and behavior of each species different from the physiology and behavior of their species-specific adulthood. Mammals must undergo a transformation phase, called youth, between the neonate and the adult. This youthful metamorphic and meta-behavioral phase is necessary while the mammal is remodeling from sucking milk to munching grass or hunting meat. During its youthful phase a mammal is not simply growing linearly into its adult form and behavior but is …

Olfactory Discrimination Of Plant Volatiles By The European Starling, Larry Clark, J Russell Mason Jan 1987

Olfactory Discrimination Of Plant Volatiles By The European Starling, Larry Clark, J Russell Mason

Larry Clark

Passerine species that re-use nest sites often incorporate fresh green vegetation into their nests, a behaviour consistent with the possibility that some birds may use chemical properties of plants to counteract the selective potential of parasites and pathogens. We tested adult starlings (Sturnus vulgaris) for their physiological capacity and behavioural ability to detect and discriminate between volatiles emitted from plant material. Multi-unit electrophysiological recordings from olfactory nerves of adults indicated that strong responses were reliably elicited by volatiles from six plant species. After pairings of plant volatiles with gastro-intestinal malaise, birds exhibited conditioned avoidance in behavioural experiments, and made all …
