Abstract
I investigated whether free-living adult golden-mantled ground squirrels (S permophilus lateralis) could learn to associate a novel sound with the appe arance of a predator. Using a classical conditioning protocol, I presented adult squirrels with a novel tone followed by the appearance of a model haw k. After repeated trials, I again measured the squirrels' behavioral respon ses to the tone and compared them with their pretraining responses. Individ uals that experienced the tone paired with the hawk responded with antipred ator behavior of longer duration after pairing than before and these respon ses were indistinguishable from responses to natural, conspecific alarm cal ls. By examining the process, rather than simply the pattern, of call recog nition ontogeny, this study provides new evidence for a mechanism by which animals can develop the ability to respond to both conspecific and heterosp ecific calls.
