Visual and olfactory stimuli contribute to anti-snake responses in mammals California ground squirrels, Spermophilus beecheyi, flag their tail and kick sand at a rattlesnake, C. viridis, more often than at a gopher snake, P. melanoleucus. The squirrels kicked sand at and approached a snake in a perforated transparent bag more frequently than one in an intact hag. Visual and chemical cues are important, but the latter seem to he the primary releasers (Henessy and Owings, 1979).

Fig. 17.3 Infrared video frames of a squirrel interacting with (a) a rattlesnake and (b) a gopher snake during experimental trials. Lighter pixel color corresponds to warmer object surface temperature. Note that the tail regions of the squirrel, referenced by the white arrows, are considerably warmer than background during the rattlesnake trial, but not the gopher snake trial.
