House Wren    Troglodytes aedon

Conservation Status

General Status in Canada : Secure

COSEWIC Status : Not assessed

Breeding Bird Surveys indicate that North American populations have remained unchanged between 1966 and 2007. In Canada, there has been no significant change in overall numbers, although populations in aspen parklands appear to have increased. The House Wren has benefited from European settlement in North America. Fragmentation of forests, urban plantings and the creation of hedgerows have provided high quality habitat for this species. Dense urban development and local destruction of hedgerows for intensive agriculture have negatively impact House Wren populations in some regions. House Wrens are an adaptable species and will readily nest in backyard birdhouses. House Wrens are secondary cavity users, dependent mainly on woodpeckers to provide suitable nest sites. In rural areas, the salvaging of dead, standing, deciduous trees for firewood negatively affects nesting habitat.
