We’re losing up to 1 billion birds to building strikes every year.
North America has lost 3 billion birds in the past half century—and building strikes are considered one significant cause of those losses. In fact, we lose up to 1 billion birds across the United States every single year due to building collisions.
Did you know that some species, like Ruby-throated Hummingbirds are more susceptible to building strikes than others?
Did you know window collisions are one of the leading direct human causes of bird mortality? Every-single year as many as 1 billion birds are killed from window strikes.
Small migratory birds like the Ruby-throated Hummingbird and American Goldfinch are particularly susceptible to collisions, especially in the fall during migration.
We’re partnering with cities and municipalities to introduce ordinances that reduce use of glass, reduce reflectivity, and dim lights during key migratory periods.
Right now more than 45 cities across the country have implemented Lights Out Campaigns, encouraging building owners and managers to turn off excess lighting during the months migrating birds are flying overhead, and a number of statewide and regional efforts are underway.
Generous support from people like you powers this work and all of our programs to protect birds for generations to come.
We need your help to protect birds
Up to 1 billion birds are killed in building collisions each year.
Species like Ruby-throated Hummingbirds and American Goldfinches are particularly susceptible to building strikes.
We're advocating for legislation like the Bird Safe Buildings Act, to help birds avoid collisions by promoting bird-friendly materials and design features at federal buildings.
We’re doing everything we can for at-risk birds. And your continued, sustained support allows us to embark on initiatives like the Lights Out Campaign on behalf of beloved birds.
