This study examined the sensory features of postnatal social experience that bobwhite quail chicks (Colinus virginianus) require to maintain species-typical responding to maternal auditory-visual cues. Chicks were reared in 1 of 3 conditions after hatching: altered tactile, auditory, or visual experience with siblings. Findings revealed that altered tactile, auditory, or visual experience during the first 36 or the first 72 hr following hatching modified chicks' preferential responding to species-specific maternal cues. During the second 36 hr, altered tactile or auditory experience disrupted chicks' perceptual development, whereas altered visual experience did not affect species-typical responsiveness. Results indicate that (a) timing of early postnatal visual experience can affect early filial responsiveness to maternal cues and (b) normal sensory experience derived from early social interaction affects species-typical perceptual development.
