Buildings Kill Birds
The Audubon Society in the US state of Minnesota has published findings from years of studies that show that high-rise buildings are one of the biggest killers of birds in urban environments. The society’s researchers say evidence shows that building design changes and window treatment can reduce some of the toll from building collisions.
In the Twin Cities of Minnesota, the Audubon Society collected over 1,400 dead birds from 2007 to 2009, representing 100 different species — mostly songbirds.
In the US, estimates hold that between 100 million and 1 billion birds die from collisions with buildings. One way of preventing this can be turning the lights off at night-time, as bright lights in the dark can confuse migrating birds.
The biggest danger can be buildings coated in reflective glass, that confuse birds and cause more collisions. As a result of these findings, the Audubon Society of Minnesota has released a booklet explaining how to make buildings less perilous for birds.
