Animals in territorial neighborhoods often show differential behavior toward different classes of conspecifics. We tested whether males of the lizard Anolis sagrei outside of their territorial neighborhoods differed in visual display behavior when matched with neighbors versus with nonneighbors. We captured nine dyads of neighbors and nine dyads of nonneighbors, placed each dyad on an artificial habitat patch in the field, and then observed display behavior for one hour. Dyads of neighbors exhibited a smaller proportion of bobbing headbob displays than did dyads of nonneighbors. The direction of this display difference is consistent with the hypothesis that neighbors were treated less aggressively than nonneighbors.
