Abstract We studied the persistence of conditioned taste aversions in sheep and whether or not sheep averted to one shrub species would avoid another shrub species. Three-month-old lambs were averted to the shrub Cercocarpus montanus by pairing its ingestion with lithium chloride (LiCl), a nonlethal gastrointestinal poison. When lambs were yearlings, they were offered C. montanus plants growing in 8-liter pots. During the persistence trial, averted sheep took fewer (P < .05) bites of C. montanus than controls did (19 vs 64 bites/sheep, respectively). Following the persistence trial, sheep that had been previously averted to C. montanus and consumed C. montanus received LiCl. Complete aversion to C. montanus was re-established in previously averted sheep with a single dose of LiCl. When sheep previously averted to C. montanus were offered potted Amelanchier alnifolia shrubs, averted sheep consumed 21 bites of A. alnifolia but controls consumed 58 bites (P < .05). This result suggests that previously averted sheep were either more food neophobic than controls or generalized their aversion from C. montanus to A. alnifolia. As with C. montanus, a single dose of LiCl completely averted sheep to A. alnifolia. When sheep grazed a pasture containing C. montanus and A. alnifolia averted sheep took fewer (P < .05) bites of the two shrubs than controls did (.2% vs 18%). Sheep showed no signs of extinguishing the aversion to either shrub during the grazing season (May-Sept.). Aversive conditioning may be useful to manipulate diet selection of free-ranging livestock.

Abstract We report two experiments designed to assess whether quality of color (and shades) influences food-aversion learning by Red-winged Blackbirds (Agelaius phoeniceus). In Experiment 1, Red-wings were given food paired with one of two shades of red or green followed by toxicant-induced sickness. In subsequent tests for generalization of the learned aversions, avoidance of red was generalized broadly to other shades of red, whereas avoidance of green appeared to be relatively stimulus specific. In Experiment 2, we pre-exposed Red-wings to a single shade of red or green in a feeding context for 4 days. Then the birds were conditioned as in Experiment 1 and tested for expression of learned color aversions. Although pre-exposure weakened expression of aversions to both colors, such effects were more pronounced for green. The effects were greater for birds pre-exposed to the conditioning color in close association with the food than for birds pre-exposed to the conditioning color away from food. Generalization of conditioned aversions and resistance to the effects of pre-exposure may reflect adaptations of Red-wings for prey selection. It would appear adaptive for birds to generalize avoidance learning broadly for conspicuously colored, noxious prey and to exhibit such learning regardless of prior experience with the color. Conversely, because few cryptically colored (e.g. green) prey are noxious, it would be adaptive for learning to be specific for the noxious individuals alone. Finally, we believe that the generalization of learned aversions could serve as a useful criterion in selecting appropriate color stimuli for use in bird control (i.e. repellency) and that the methods presented here could provide one empirical means of assessing such generalizations.
