Nature Moncton organized a nest box cleaning event over the weekend to maintain habitats for birds like tree swallows. The project, started eight years ago, addresses declines in bird populations due to habitat loss. Volunteers monitor and clean boxes across New Brunswick to support nesting.
Substrate placeholder — needs reviewNature Moncton, a nature group in New Brunswick, hosted its annual nest box cleaning event on the weekend. Nest boxes are enclosed wooden structures designed to provide replacement habitats for natural tree cavities used by birds. The event involved volunteers monitoring and clearing these boxes to prepare them for the nesting season.
The nesting box project began eight years ago to support declining populations of insect-eating birds, including tree swallows. Fred Richards, past president and current board member of Nature Moncton, stated that the initiative aims to provide habitat in areas where birds are present.
According to the Canadian Breeding Bird Survey, tree swallow populations in New Brunswick have declined since the 1970s.
Nature Moncton monitors nest boxes in locations including Moncton, Sackville, and Memramcook. Richards reported that he has constructed over 600 nesting boxes for the group, now placed across the province. These boxes help address habitat loss, which contributes to the bird population decline.
The cleaning process requires using a drill to open one side of the box.
Volunteers remove debris and inspect for signs of previous occupancy, such as white feathers indicating tree swallow use. Tree swallows require clean nests each year to avoid mites that feed on young birds. Richards explained that cleaning removes old nest material and adds substances to eliminate mites, improving survival chances for new broods.
Marbeth Wilson, vice-president of Nature Moncton, noted that urban development contributes to habitat loss for birds. She observed that some boxes along the Riverfront Trail in Moncton showed no nest debris, possibly due to noise from a nearby construction site.
all boxes are occupied annually, but the project has supported species including tree swallows, eastern bluebirds, and chickadees over the years.
Richards identified additional factors in the tree swallow decline, such as reduced insect food sources from pesticide use. He emphasized that while 600 boxes represent a small portion of the province's bird population, they provide targeted habitat support. The initiative highlights ongoing efforts to mitigate environmental pressures on local wildlife.
Future events will continue monitoring to track usage and adjust placements as needed. Nature groups like Moncton play a role in community-based conservation amid broader habitat challenges.
Temperatures approached 40 degrees Celsius across much of western and central Europe on June 21, prompting red alerts, rail cancellations, and wildfire evacuations. The heat surge is expected to continue at least until midweek.
The BbcFrance issued red heatwave alerts for roughly half the country, including Paris, as temperatures approached record levels. Parisians sought relief by swimming in the Canal St Martin.
Officials reported 1,003 confirmed cases and 254 deaths from an Ebola outbreak centered in Ituri province. The outbreak, caused by the rare Bundibugyo virus, began May 15 and has spread to neighboring provinces and Uganda.
