Go Lights Out Spring 2024

SPRING MIGRATION WRAP-UP:

The statewide peak night was on April 19 with nearly 8 Million birds passing over the state! The Multnomah County peak night was on April 23 with 1.3 Million birds passing over the county!

Between April 15 and May 19, we had a total of an estimated 78.7 M birds cross Oregon and 9.6 M cross the County!
We had some early high traffic nights this year, so between April 9 and May 20, an estimated 91.2 Million birds crossed over Oregon and 11.4 Million birds crossed the County.


Mark your calendars for the annual Lights Out Portland period from April 15 through May 19, a community-wide event tied to peak fall migration season when millions of birds will be passing over Oregon skies! Residential households and commercial buildings will dim their lighting in order to raise awareness about the impact of light pollution on migrating birds, about wasted energy in the form of light thrown up into the sky, and about preserving our ability to see stars from the city.

Building owners, businesses, and residents are encouraged to join us from 11 p.m. to dawn each night through May 15 – the period during which peak numbers of birds will be moving through our airspace. A big thank you to participating buildings including the Bonneville Power Administration, US Bancorp Tower, Wells Fargo Tower, Metro Regional Center, Oregon Convention Center, City Hall, Portland Building, 1900 Building, 200 Market, KOIN, Fox Tower, Park Ave West, 911 Federal Building, Lloyd 700 Building, Lloyd Center Tower, First and Main, Montgomery Park, OMSI, OHSU SW (CHH1, CHH2, RPV, RLSB, KCRB), 1201 Lloyd, B of A Financial Center, Multnomah County Central Courthouse, East Portland Community Center, Mt.

Go Lights Out!

Light Pollution drowns out the stars that migrating birds are using to navigate and lures them into cities where they are at risk of colliding with windows. Across the US, nearly 1 billion birds die every year as a result of hitting a window. There are also serious human health concerns about exposure to artificial light at night, which disrupts our circadian rhythms.

Building owners, tenants in residential buildings, and residential households are encouraged to turn off unnecessary lighting and then get out somewhere to see the stars!

From 11 p.m. to dawn, building owners are asked to:

    • Turn off rooftop lighting
    • Turn off or dim exterior architectural lighting
    • Turn off or dim lobby/atrium lighting
    • Turn off interior lights in unoccupied spaces (or have interior lighting on motion sensors)
    • Ask tenants to close blinds or drapes; feel free to share the attached Lights Out postcard with your folks!
    • Safety and security lighting is exempt

Folks in houses, apartments and condos are asked to:

    • Turn off any unnecessary outdoor lighting
    • Draw blinds or curtains in rooms where lights are in use
    • Take the Pledge to Go Lights Out here!
    • Get outside to see the night sky!

 

Take the Pledge to Go Lights Out!
