Birdhouse w/Winter Wren Line Drawing, Wood. Birdhouse wren silhouette. This birdhouse has been designed for the Wren. Place the birdhouse on a tree or wall, at a height of up to 2 m (6.6 ft) in a well hidden spot between dense bushes or ivy plants, at a quiet and somewhat sheltered spot, therefore not in the direct sunlight or on the side catching the rain, and an obstacle-free approach route for the bird. Fall is the best season to clean out the birdhouse.Many times during winter the bird house offers protection to birds seeking shelter in severe weather conditions.. The burned silhouette with the name in Latin says it all, this birdhouse is ideal for the Eurasian wren when nesting and during winter months. Using the lateral flap the nesting box can be cleaned easily, when it is not occupied.
