Pictures of predators at sound walls in apartment complexes did not keep birds from colliding with barriers

Using pictures of predatory birds on transparent sound walls at two apartment complexes does not prevent birds from colliding with the barriers, according to The ‘Angry Vegans’, an animal rights organization active in the southwestern city of Gwangju.

The barriers keep noise from transmitting from noisy upstairs neighbors, through adjacent party walls between neighboring units, or windows.

The noise control problems range from airborne noise transmission from voices, TVs, music to plumbing noise.

The group vowed to conduct a thorough investigation into bird collisions in the area next year.

In its preliminary study, the organization found that 51 birds perished in a single day after colliding with transparent sound barriers. Among them are 41 birds that died in collisions at one of the sound barrier walls at a local apartment complex. Another 10 birds were found dead in a soundproof wall in a different apartment complex that did not have any pictures of the birds of prey.
