Check out the article in today's Oregonian regarding bird collisions with buildings:

Bird collisions with buildings is actually the number one cause of bird deaths in the United States after habitat loss. Hundreds of millions of birds are estimated to die in collisions with birds each year. In fact some of our rator cam fledglings have been injired in colllisions with windows as they learned to fly.  However the most significant numbes of bird mortalities occur during migratory periods. Many species of birds migrate at night and are drawn towards tall lit buildings especially during migratory periods.

Audubon has been studying the problem in Portland and encouraging some of our taller buildings to reduce unecessary lighting during migratory periods. Similar "lighs out" programs have been adopted in cities across North America including Chicago, New York, and Toronto. Read more about Audubon's Bird Safe Program and Lights Out Campaign.

This Saturday is an event called Earth Hour, a global sustainability event in which 50 million people across 35 countries and territories are expected to turn off lights from 8:30 to 9:30 p.m. to raise awareness of the mriad impacts of light pollution.
