Transparent sound barriers prevent birds from colliding, losing sight or breaking their beaks. The animals are suffering, but the safety measures are insufficient.

It is a soundproof wall installed along the national road.

About a week ago a bird, a natural monument, was rescued after crashing into a soundproof wall.

I lost my sight to the concussion because of the shock.

Even if it is fed, the beak pecks in the wrong place and cannot find it properly.

[Lee Mun-hee / Chungnam Wildlife Rescue Center veterinarian: The shock is transmitted indirectly to the rear eye, which damages the structure that controls the vision behind the eyeball.] The gossip that hit the window broke its beak.

You need to open your mouth and feed.

Some have broken wings and undergo surgery.

Why are raptors soaring in the soundproof walls?

[Lee Min-min / Wildlife Rehabilitation Manager: Sometimes I run into chasing animals that are prey and hunting.]

The sound barrier where the hawks collided.

The height was low but the collision could not be avoided.

There are no collision reduction devices such as blind spot stickers.

The eagle, who came to spend the winter, was unable to eat and was exhausted and rescued. Four of the elk crossing the roadway were hit by a car and hurt their legs.

Last year, more than 2,900 animals were rescued from collisions across the country, and 762 wild animals were rescued from exhaustion.
