“Collisions with windows are one of the biggest human-related causes of bird deaths in the United States, responsible for up to one billion avian fatalities every year. That’s as much as 9 percent of the country’s entire bird population.
In general, the more windows and the bigger windows a building has, the more dangerous it is for birds. Many green buildings are designed with lots of windows to reduce the need for artificial light and heating. So there can be a tension between saving energy and saving birds.
Glass with etched patterns, mullions, or UV-reflective films can help birds recognize windows as a barrier and avoid flying into them. But scientists have incomplete knowledge of how well these measures work, as well as what aspects of buildings and biology make birds more vulnerable to window strikes in the first place.
Two recent studies conducted on opposite sides of the country fill in some of these details...”
Some alternations of our buildings and bird-friendly designs appear reasonable and responsible. Now if we can reduce mortality due to our domesticated cats...
