"Skyscrapers, communication towers and wind turbines are a regular sight in our
daily lives, but if you're a bird, they can be a dangerous obstacle course.
Each year, billions of birds fly straight into these towering structures,
making it one of the leading causes of human-related bird deaths worldwide.
There has been no shortage of attempted solutions, from marking windows to
placing special lights on top of buildings and towers.
However, while bright markings and lights stand out to the human eye, they have
done little to prevent birds from crashing into them.
Now, a team of researchers in the US have used sound waves to prevent birds
from slamming into tall communication towers.
These "acoustic lighthouses" reduced the number of birds flying close to the
towers by up to 16 per cent, helping to cut the risk of fatal collisions."
