If you have driven, cycled or walked along Riverside Drive, six wooden structures have likely caught your eye.

These are oversized bird houses for the endangered barn swallow, which have been displaced due to ongoing construction at nearby McIlwraith Bridge.

The Ontario Ministry of Natural Resources requires the city to offer an alternative nesting ground when an endangered species is affected by road or bridge work.

Check out the photos above for more details on the wooden bird houses and the barn swallow.
