“Halifax Resident Advocates Nesting Boxes for Tree Swallows”

Aiming to aid tree swallows in finding suitable habitats for breeding, a Halifax resident is advocating for the construction and installation of nesting boxes on residential properties.

Jessica Ryuzaki shared that the inspiration struck her during a casual stroll in the city, prompted by the noticeable decline in trees due to deforestation and its potential impact on local wildlife, particularly birds, which she views as integral to the community.

Tree swallows, among other aerial insectivores, have experienced dwindling numbers in Nova Scotia and P.E.I since the 1970s, as reported by the Canadian Breeding Bird Survey. These cavity-nesters prefer dwelling in tree holes or crevices.

The concept of nesting boxes to provide alternative housing for birds when natural habitats are scarce is not novel. Ryuzaki emphasized the simplicity and affordability of constructing such boxes, suggesting that basic materials, even from a dollar store, suffice for the project.

For instance, Ryuzaki built her own nesting box for under $20 within 30 minutes, using scrap wood, an entrance hole, and a side panel for easy cleaning.

Tony Millard, president of the Nova Scotia Bird Society, endorsed Ryuzaki’s initiative and leveraged social media to raise awareness. He advised that nesting boxes should be mounted in sunny, open grassy areas, approximately two meters above ground level to safeguard against ground predators. Additionally, proper orientation, facing south or east, shields the birds from harsh winds.

The project, now named ReNest Nova Scotia, is providing templates for constructing the boxes.

Millard highlighted the potential benefits of these boxes for various bird species and homeowners, emphasizing the joy of observing swallows feeding on insects in the yard, while also reducing pest populations.

He recommended constructing the boxes during winter, suggesting completion by April to meet the birds’ needs in spring. Ryuzaki expressed receiving positive responses from residents interested in participating, hopeful to witness the boxes installed across yards in the upcoming season.

“Having a nesting box in every Halifax property would be truly remarkable. I’d be thrilled if that vision materializes,” she remarked.
