Figure 1.

Rattlesnake responses (strike, 1; no strike, 0) to squirrels that either tail-flagged (black triangle) or not (grey diamond) at various distances within their observed strike range (31 cm). All data points were either 1 or 0; we jittered the location of data points around 1 and 0 to avoid overlapping values. The black solid line indicates our model's predicted probability of snakes striking at tail-flagging squirrels as a function of distance. The grey-dashed line indicates the predicted probability of snakes striking at non-tail-flagging squirrels as a function of distance.
