Tip of the Week: Vaux’s Swifts
Vaux’s Swifts are amazing little birds that naturally nest in large old hollow trees. However in the absence of large trees, they have adapted to use chimneys. It is not uncommon for residents in the metro region to discover that swifts have taken up residence in their chimney. The first sign is often the raucous calls of the young begging to be fed. Occasionally a swift will fall out of their nest and wind up in people’s fireplaces. This link will take you to interesting information about swifts and what to do if you discover that they are living in your chimney!
