It's that time of year again where we move our clocks forward one hour and remember to turn off our outdoor lights out at night in support of the migratory bird populations.
This image is North America at night as seen from space. Bright lights at night obscure birds' navigational aids and make it challenging for them to find their way out of developed areas and along their migratory paths.
Check Portland Audubon Society's suggestions for how residents can help protect birds and other wildlife from light pollution.
