Halifax Resident Promotes Nesting Boxes for Tree Swallows
To aid the nesting efforts of tree swallows, a Halifax local is advocating for the construction and installation of nesting boxes on residential properties in the area. Jessica Ryuzaki, the initiator of this project, was inspired by the diminishing tree population in the city during one of her walks, prompting her to consider the impact on local wildlife, especially birds.
According to data from the Canadian Breeding Bird Survey, tree swallows and other aerial insectivores have experienced a decline in population in Nova Scotia and P.E.I since the 1970s. These birds are cavity-nesters, preferring to reside in holes or crevices within trees. While the idea of nesting boxes is not novel in providing additional homes for birds when natural habitats are lacking, Ryuzaki emphasizes the simplicity and affordability of creating these boxes.
Ryuzaki mentioned that constructing a nesting box can be done inexpensively with materials readily available, such as scrap wood, and does not require extensive woodworking skills. Tony Millard, the president of the Nova Scotia Bird Society, endorsed Ryuzaki’s initiative and highlighted the importance of strategic box placement in open, sunny areas to safeguard the birds from ground predators. Additionally, guidance on box construction and templates are being shared under the project, now named ReNest Nova Scotia.
Millard pointed out that these nesting boxes are not exclusive to tree swallows and could benefit various bird species. Homeowners participating in this project can enjoy the spectacle of swallows hunting insects in their yards, contributing to natural pest control. As winter is an optimal time for constructing nesting boxes, individuals are encouraged to engage in this activity indoors, ensuring the boxes are ready before April, just in time for the birds’ nesting season.
Ryuzaki expressed enthusiasm for the community’s involvement in this initiative and hopes to see a significant number of nesting boxes set up across Halifax. The project has garnered interest from numerous individuals, with the true impact expected to be observed in the spring when the boxes are put to use.
