Reducing Bird Collisions with Buildings and Building Glass

Service Releases New Best Practices Document

Bird collisions associated with building glass and building lighting are hazards for which a variety of potential avoidance and minimization options exist. The U.S. Fish & Wildlife Service recently released its  Reducing Bird Collisions with Buildings and Building Glass Best Practices (1.8MB) document.

Annual bird mortality resulting from window collisions in the U.S. is significant. While most people consider bird and building collisions an urban phenomenon involving tall, mirrored-glass skyscrapers, the reality is that 56 percent of collision mortality occurs at low-rise (i.e., one to three story) buildings, 44 percent at urban and rural residences, and less than 1 percent at high rises.

As part of the effort to address human-caused sources of bird mortality, the Service's Migratory Bird Program, in partnership with experts in the field of bird impacts from building, glass and lighting, has developed recommendations for addressing bird collisions with buildings.

This document is intended to provide straightforward options for reducing bird collisions with buildings by offering recommendations for simple, no-cost building occupant best practices; low cost avoidance and minimization actions; and strategies for new buildings, building renovations, and building retrofits.

The Service owns and leases many buildings, and efforts are underway to address bird collisions at a number of these facilities. These efforts include providing information to Service employees about measures that they and others can implement in their office buildings to reduce bird mortality.

We strive to lead by example with efforts to protect migratory birds, but we can not do it alone. Our agency partners on the Council for the Conservation of Migratory Birds, and others, will also disseminate this information widely and staff to look for ways to help prevent and reduce bird impacts in their homes and offices. We encourage everyone to consider how they might use these guidelines.
