An initiative in Halifax is urging residents to construct and set up nesting boxes to aid tree swallows in finding homes and breeding successfully. Jessica Ryuzaki, the brain behind the idea, was inspired while observing tree removal in the city and contemplating its impact on local wildlife, particularly birds. Notably, tree swallows and similar 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.
Nesting boxes, a common solution to provide housing for birds in tree-scarce environments, are deemed simple and affordable to create, according to Ryuzaki. By using basic materials such as scrap wood, building a nesting box can be achieved inexpensively and quickly. Tony Millard, the president of the Nova Scotia Bird Society, endorsed the idea and is promoting it through social media channels.
These nesting boxes are meant to be positioned in open, sunny locations about two meters above the ground to protect the birds from ground predators. Additionally, they should face south or east to shield them from strong winds. The initiative, now dubbed ReNest Nova Scotia, is offering templates to assist individuals in constructing these boxes.
Apart from aiding tree swallows, the nesting boxes can benefit other bird species and homeowners alike by controlling insect populations. Millard emphasized the joy of observing swallows in one’s yard, contributing to pest control naturally. With winter being the opportune time for construction, individuals are encouraged to build and install the nesting boxes before April to support the upcoming breeding season.
Ryuzaki expressed optimism about the community’s involvement in the project and anticipates a clearer picture in spring when the boxes will hopefully adorn numerous yards across Halifax. Encouraging widespread participation, she envisions a city filled with nesting boxes as a fantastic outcome.
