Hundreds of millions of birds die each year from crashing into windows
Between 365 and 988 million birds die from crashing into windows in the United States each year, according to a new report. That may be as much as 10 percent of the estimated total bird population of the country.
The estimate puts windows behind only cats as the largest source of human-related menaces that kill birds directly.
The biggest share of the collision deaths comes not from glass massacres at skyscrapers but from occasional collisions with the nation’s many small buildings, saysScott Loss of Oklahoma State University in Stillwater. “It’s death by a million nicks.”
