we were really interested in identifying with the confusion of birds in an aviary. since we live in a space that is spacially comparable to a birdcage...we replicated the bird calls of a wild turkey, an owl, a crow, and tweety. as you will observe in the audio track, the crow and wild turkey get increasingly agitated as the owl and tweety remain calm. at one point the tweety bird even seems to laugh at the antics of the larger more aggressive yet perhaps insecure birds.
