Turn out the lights. Help the birds.

That is the message Mayor Steve Adler is sending to Austin residents this spring.

"You can help keep migrating birds safe through their migration season by turning off lights between 11 p.m. and 6 a.m.,” the mayor said on Twitter.

He linked to an organization of researchers on bird migration called BirdCast, which provides information to building owners about how to help reduce light pollution in urban areas during migration season. The group is part of a programs called “Lights Out Texas” and says the state is crucial for bird migration.

“Approximately 1 of every 3 birds migrating through the U.S. in spring, and 1 of every 4 bird migrating through the U.S. in the fall, or nearly two billion birds, pass through Texas,” it said. “Protecting birds in Texas promotes conservation of bird populations across the Americas.”

In addition to turning out lights each night, building owners should avoid floodlights, not illuminate interior plants or fountains, and keep unoccupied floors dark. They should try to schedule cleaning crews during daylight hours if possible, the group said.

Essential lights, such as security lights, can be aimed down or include shields to keep them from shining into the sky or trees.

“Use motion detectors and sensors so lights are only on when you need them,” the group said.

Desk lamps instead of overhead lighting can also help.

“ Do not use landscape lighting to light up trees or gardens where birds may be resting,” it said.  “Close blinds at night to reduce the amount of light being emitted from windows.”

Each year, an estimated one billion birds die from colliding with buildings and structure and migratory birds are at the most risk, according to the group. The worldwide bird population has declined by a fourth since 1970, it said.
