To ascertain whether an ambush forager might select ambush posts bearing chemical cues, I presented emerald swifts (Sceloporus malachiticus) a choice between two ambush posts affording minimally overlapping views. One post was labeled with chemical cues from mealworms, the other was unlabeled. Occupancy of ambush posts was random with respect to mealworm scent. It appears that ambush foragers use chemical cues neither to locate and identify prey nor to select ambush posts.
