Federal Bird Safe Buildings Act of 2023

This bill requires federal agencies to incorporate bird-safe design features in public buildings during construction, acquisition, or major renovations (over 50% facade alteration). It mandates the General Services Administration to develop and update a design guide with strategies like specialized glass, lighting modifications, and maintenance practices to reduce bird collisions. The guide must be shared with all federal agencies and include input from bird conservation experts. Exemptions apply to historic sites, the White House, Supreme Court, and Capitol complex. Annual reports on compliance and bird fatality assessments must be submitted to Congress.
