A woman in Halifax is advocating for the creation and installation of nesting boxes to support tree swallows in finding suitable habitats for breeding.
Jessica Ryuzaki was inspired to promote this initiative after observing the reduction of trees in the city and contemplating the impact on local wildlife, particularly birds.
Tree swallows and other aerial insectivores have experienced a decline in population in Nova Scotia and P.E.I since the 1970s, as reported by the Canadian Breeding Bird Survey. These birds typically nest in cavities within trees.
Constructing nesting boxes is a known method to offer new homes for birds in areas lacking sufficient trees. Ryuzaki emphasized the simplicity and affordability of building these boxes, suggesting that basic materials from inexpensive sources like dollar stores can be used.
She shared that she spent under $20 on materials and completed the construction of her own nesting box in just half an hour. The key components are scrap wood, an entrance hole, and a side panel for easy maintenance.
Tony Millard, the president of the Nova Scotia Bird Society, endorsed Ryuzaki’s initiative and is helping to promote it on social media.
According to Millard, the ideal placement for these nesting boxes is in sunny, open grassy areas about two meters above the ground to protect the birds from ground predators. Additionally, the boxes should face south or east to shield them from strong winds.
The project, now known as ReNest Nova Scotia, is providing templates to guide individuals in constructing the nesting boxes.
Millard highlighted that these nesting boxes can benefit various bird species beyond tree swallows. He also mentioned the advantages for homeowners, including reduced insect presence in their yards due to the birds consuming pests.
Winter is recommended as the ideal time for construction, allowing individuals to build and install the nesting boxes before April, ensuring they are ready for the upcoming spring when the birds will require them.
Ryuzaki expressed enthusiasm for the community response, indicating that many individuals have expressed interest in participating. She eagerly anticipates seeing the boxes in yards during her spring walks.
“It would be fantastic if every household in Halifax could set up a nesting box. I would be thrilled to see that,” she remarked.
