Engineering Bird-Friendly Glass on PBS (scitech)now

Every year hundreds of millions of birds die from accidentally flying into glass buildings and windows. But now, new types of glass may make this easily preventable. Daniel Klem, Professor of Ornithology and Conservation Biology at Muhlenberg College in Pennsylvania joins Hari Sreenivasan to discuss creating bird-friendly glass.


The Cornell Lab of Ornithology: Why Birds Hit Windows—And How You Can Help Prevent It

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.


Bird–Window Collisions: A Critical Animal Welfare and Conservation Issue, Journal of Applied Animal Welfare Science, 2015

Sheet glass and plastic in the form of clear and reflective windows are universally lethal to birds. Reasonable interpretation of available scientific evidence describes windows as a principal human-associated avian mortality factor that is an indiscriminate killer of common species as well as species of conservation concern. A conservative toll estimates 1 billion or more annual fatalities in the United States alone.

When you are alone for days or weeks at a time, you eventually become drawn to people. Talking to randos is the norm. I’ll never forget the conversation with the aquarium fisherman, forest ranger, and women at the Thai market. It’s refreshing to compare notes on life with people from vastly different backgrounds.
