Consilium Place, Ontario, Canada


This complex consists of three buildings that experienced an unusual number of bird strikes, especially during the spring and fall migrations. The complex is in line with a natural flyway and both the windows and spandrels consist of highly reflective glass. A number of possible solutions were evaluated but none met all the needs of the property manager from the standpoint of preventing bird strikes, attractive appearance, longevity and cost.


A Feather Friendly® Technology specifically designed for a retrofit solution to deterring bird collisions was applied to the entire exterior surface of the first four stories on two elevations on two towers as well as the atrium.

Town of Markham, Ontario, Canada
A Happy Ending!


The Town of Markham had a serious problem with bird deaths associated with collisions with glass on one of their buildings.  The atrium entrance at 8100 Warden initially contained shrubs and trees so these were removed to help alleviate some of the problem.  Unfortunately, birds continued to attempt to fly into the glass in hopes of reaching the foliage on the other side of the atrium.  Bird silhouette stickers also had no effect in reducing collisions.  Additionally, the reflective glass on the two storey building also experienced a large number of bird deaths, especially in the spring and fall. 


A Feather Friendly® Solution specifically designed for deterring bird collisions was applied to the exterior surface of the atrium as well as the reflective east facing windows to the height of the adjoining trees.

Customer Comments:

When we moved into the facility a few years ago, we were disturbed to regularly find injured or dead birds on the ground below our windows.  We strongly felt that it was our collective responsibility to show leadership in create a sustainable community that is healthy for all creatures.  Once we recognized that we could do something to reduce bird strikes, we made the decision to have the specialized solution installed on the exterior of our atrium and east facing windows.  While the solution was being installed observers noted that birds continued to strike the windows that had not been protected.  We are delighted that since the installation, there have been no reported bird collisions with the protected glass.  Now that we have seen the results firsthand, we are moving ahead on our other properties with a similar problem.  We also will be encouraging the citizens of Markham to do the same.
