If you have had the opportunity to travel down the Highway 401 corridor between Windsor and London you will have noticed several odd looking roofed structures on either side . Although they are very unusual buildings, they are provided for one of our declining swallow species, the Barn swallow (Hirundo rustica) often seen in countrysides and around farm buildings. Efforts are being made to return them to their original numbers as their former habitats are being removed, closed or destroyed. The next time you travel this route or other routes in Ontario, you’ll understand why these odd looking structures are standing.
The Ministry of Natural Resources has set up some specific guidelines on Altering Barn Swallow Habitat at their website .
