A Halifax resident, Jessica Ryuzaki, is advocating for the construction and installation of nesting boxes to assist tree swallows in finding suitable habitats for breeding.
Ryuzaki’s inspiration came while observing the diminishing tree population in the city and contemplating the impact on local wildlife, particularly birds.
According to the Canadian Breeding Bird Survey, tree swallows and other aerial insectivores have experienced population declines in Nova Scotia and P.E.I since the 1970s. These birds are cavity-nesters, preferring holes or crevices within trees.
While the concept of nesting boxes is not novel, Ryuzaki emphasizes its simplicity and affordability, noting that materials for construction can be easily obtained, even from budget stores.
Ryuzaki spent under $20 and 30 minutes to build her own nesting box using scrap wood, an entrance hole, and a pivoting side panel for cleaning.
Tony Millard, the president of the Nova Scotia Bird Society, endorsed Ryuzaki’s initiative and is leveraging social media to promote the cause.
For optimal placement, Millard advises mounting nesting boxes in sunny, open, grassy areas about two meters off the ground to safeguard birds from ground predators. The boxes should face south or east to shield against harsh winds.
The project, now known as ReNest Nova Scotia, is providing templates to aid in the construction of these nesting boxes.
Millard highlights the benefits of nesting boxes not only for tree swallows but also for other bird species. Homeowners participating in the project can enjoy the sight of swallows controlling insect populations in their yards.
Winter is identified as the ideal time for constructing and installing nesting boxes, ensuring they are ready before spring, when birds will require them.
Ryuzaki has received significant interest from individuals wanting to contribute to the project, anticipating more participation in the spring when the nesting boxes will be visible across yards in Halifax.
“The widespread adoption of nesting boxes in Halifax would be truly remarkable. I would be thrilled to see this come to fruition,” Ryuzaki expressed.
