In a bid to assist tree swallows in finding suitable habitats for breeding, a Halifax resident is advocating for the construction and installation of nesting boxes on private properties. Jessica Ryuzaki shared that the inspiration for this project struck her while she was out exploring the city and noticing the increased tree removal activities impacting local wildlife, especially birds, which she views as vital members of the community.
According to data from the Canadian Breeding Bird Survey, tree swallows and similar aerial insectivores have faced population declines in Nova Scotia and P.E.I since the 1970s. These cavity-nesting birds prefer living in tree holes or crevices. Nesting boxes have been a known solution to provide alternative homes for birds when natural habitats are lacking, and Ryuzaki emphasized that constructing a box is straightforward and budget-friendly, requiring basic materials that can be easily acquired.
Tony Millard, president of the Nova Scotia Bird Society, endorsed Ryuzaki’s initiative and promoted it on social media. He advised that nesting boxes should be positioned in open, sunny areas around two meters above the ground to protect the birds from ground predators. The boxes should face south or east to shield the inhabitants from harsh winds. The project, now known as ReNest Nova Scotia, is also offering templates to guide individuals in making these boxes.
Millard highlighted that these nesting boxes can benefit various bird species beyond tree swallows, and homeowners participating in the project can enjoy the spectacle of swallows controlling insect populations in their yards. He recommended constructing and installing the boxes during winter, ensuring they are ready by April for the upcoming breeding season.
Ryuzaki expressed excitement over the community’s interest in participating in the project, hopeful that many will join in constructing and placing nesting boxes around Halifax. She anticipated seeing the boxes in yards during spring and encouraged widespread involvement in this conservation effort.
