With the increase of mixed species exhibits in zoos, targeting enrichment for individual species may be problematic. Often, mammals may be the primary targets of enrichment, yet other species that share their environment will unavoidably be exposed to the enrichment as well. The purpose of this study was to determine if auditory stimuli designed for enrichment of primates influenced the behavior of captive birds in the zoo setting. Three different African bird species were observed at the Buffalo Zoo during exposure to natural sounds, classical music and rock music. The results revealed that the average frequency of flying in all three bird species increased with naturalistic sounds and decreased with rock music (F3,6=7.63;P< 0.01); vocalizations for two of the three species (Superb Starlings and Mousebirds) increased (F2,6=18.61;P< 0.01) in response to all auditory stimuli, however one species (Lady Ross's Turacos) increased frequency of duetting only in response to rock music (X2=18.5,df = 2;P< 0.01). Auditory enrichment implemented for large mammals may influence behavior in non‐target species as well, in this case leading to increased activity by birds.
