“…Instead, it may reflect an ability to accurately discriminate among odors of different types (Adrian 195 1, Bang 197 1). Domestic pigeons (Columba livia), with a bulbto-hemisphere ratio in the middle range (18%; Bang 1971), discriminate odors in laboratory experiments (Shumake et al 1969) and appear to use scent as one of the cues for homing (Papi et al 1973(Papi et al , 1978Benvenuti et al 1973;Wald-Vogel et al 1978). Members of a species with small olfactory bulbs may be sensitive to particular odors important to their survival.…”

Although the importance of olfaction in birds is being increasingly recognized, its role in species with very small olfactory bulbs, such as corvids, is largely unknown. In field experiments designed to examine whether Black-billed Magpies (Pica pica) use olfaction to locate hidden food, we found that magpies uncovered significantly more caches of suet and raisins scented with cod liver oil than control caches. We suggest that in recovering caches, magpies use a multicue system that may involve both memory and visual or olfactory cues. Olfactory cues may be particularly important in finding and taking food hidden by other individuals. _

“…In an extensive anatomical survey of 15 1 species in 23 orders, Bang and Cobb (1968) and Bang (197 1) measured the relative diameters of the olfactory bulb and ipsilateral hemisphere, finding a 12-fold variation in the ratio of these dimensions. Behavioral studies on Rock Doves (Columba livia; Michelsen 1959, Henton et al 1966. Shumake et al 1969.…”

“…Michaelson (16) demonstrated that pigeons can discriminate between the presence and absence of olfactory stimuli. The pigeon's absolute detection threshold and thresholds for the detection of differences in stimulus intensity have now been described (17)(18)(19)(20). Much of this work has been done using conditioned suppression, a technique whose application to animal psychophysics has been reviewed (21).…”

They can be used as discriminative stimuli at concentrations above the olfactory threshold. Inhalants can elicit unconditioned reflexes. As aversive stimuli, they can be studied in respondent conditioning experiments (e.g. conditioned suppression), in punishment paradigms, or as negative reinforcers in escape paradigms. Inhalants can also be positive reinforcers; their intoxicating properties have engendered patterns of chronic self-administration (solvent abuse). Such stimulus properties should be considered in industrial hygiene and environmental quality decisions. Laboratory techniques to study such properties abound. Toxicology must deal with a large variety of atmospheric contaminants possessing a vast array of toxic effects. Such contaminants include gases and vapors, which may be asphyxiants, irritants, metabolic poisons or carcinogens, and aerosols in the form of dusts, fumes, smokes, mists, fogs, andsmogs. The respiratory system is an efficient route of entry for such substances. The pervasive presence of atmospheric pollutants behooves us to examine the effects of representative agents that pose environmental or occupational hazards. This paper will discuss techniques suitable for characterizing the behavioral significance of airborne contaminants as stimulus events that can control behavior. It will not emphasize their role in the toxicologic impairment of behavior. Techniques used to evaluate poisons administered by other routes generally can be used to evaluate the behavioral effects of inhaled substances.Studies of the behavioral effects and stimulus properties of inhaled agents require the investigator to master both the behavioral technology and the instrumental techniques for generating and monitoring test atmospheres. Perhaps this need for a dual apprenticeship explains the relative paucity of experimental work in this area. Fortunately, a number of good reference works are available (1-4).
