    At Jefferson National Expansion Memorial, the Gateway Arch it has been decided that for the last fortnight of September the floodlights will be turned off for the benefit of nearby migrating birds.

    The thousands of artificial lights throughout the city have a devastating affect on birds natural migration. Birds follow the stars for navigation and the bright, artificial lights can confuse the birds and throw them off course.

    Some birds that are distracted by lights veer away from the flyways and temporarily lose their way. Some flutter near bright lights until they are exhausted and fall to the ground. Many die in collisions with buildings and brightly lit windows.

    Turning off lights in cities during the peak migration periods can dramatically reduce bird death toll in urban cities. Many cities now accordingly participate in “lights out” programs that are sponsored or approved by the Audubon Society and other bird-friendly NGOs.

    The Jefferson national expansion memorial has also scheduled another two-week “lights out” next spring for the nest bird migration period.
