Abstract

An operant delayed-non-matching-to-sample task using computer-presented images was used to test memory for position and object (shape and colour) cues in four species of tit (Parus), two food-storing species (P. palustris and P. ater) and two non-storing species (P. major and P caeruleus). Both storers and non-storers performed successfully at retention intervals as long as 100 sec on all trial types, and there were no significant differences in performance between the two groups on any of the trial types. Performance by both groups was highest on trials in which both object and position cues were available and poorest on trials when object cues only were relevant. These data do not provide support for the hypothesis that food storers have a better memory for spatial cues than do non-storers.
