Eastern Bluebirds are nesting again at Mather Meadows, a property of the Darien (Conn.) Land Trust. Here are some photos I took during a quick visit on Tuesday morning. (More photos below — click on “continue reading.”)
Eastern Bluebirds have made a strong comeback following a decline due to several factors, including competition for nesting sites with introduced species such as House Sparrows and European Starlings. The comeback has been bolstered in large part to humans offering nesting sites to bluebirds, a.k.a bluebird houses. The houses are built to specific dimensions, including the entry/exit hole sized to keep out sparrows and starlings. Bluebirds still face competition for those homes from Tree Sparrows, but the competition is not as fierce.
