The lazy, buzzy song of the Black-throated Blue Warbler can often be heard in the undergrowth of leafy eastern woods. But these beloved birds are facing big challenges during their fall migration: Artificial lights from urban areas, buildings, and other structures can cause birds to become confused and stray off course, leading to exhaustion and increased risk of collisions with buildings, windows, and other obstacles. Collision events like these claim the lives of an estimated more than 1 billion birds annually in the US alone.
These vulnerable birds can’t ask for your help. So we’re asking for them: Will you start an annual donation now to protect the birds we love? For a limited time, your first gift will be matched, up to $40,000 thanks to a group of generous donors—so please, start your dependable gift right away.
