Birds have been shown to discriminate reward cues and spatial in a manner similar primates, but the effects of selection history on attention birds remain unclear. Like eyesight is usually most critical modality for birds, allowing them fly, evade predators, forage food, evaluate potential mating partners. Here we used Indian Peafowl (Pavo cristatus Linnaeus 1758) as our avian model adapted cueing paradigm investigate how influenced by one particular component – history. Three female peahens were trained individual components task until they could complete sequence pecking an initial fixation point followed peripheral onset target within 4 second time limit. After which, randomly assigned color-reward association pairing color cue appearing 550ms before was added task. High-value predicted two food pellets 80% pellet 20% time, low-value no time. Cues uninformative with respect location upcoming target. We analyzed RT each bird separately validity (valid vs. invalid), value (high low), their interaction. For (1406 trials), observed significant effect interaction between validity. another (902 marginal value. Our last did not exhibit any at 404 trials. preliminary findings suggest that influences similarly taxonomic classes mammals aves.
