Influx of chimney swifts in N.B., promising sign for threatened species: experts
- On the evening of May 25, 2025, over 2,400 chimney swifts were observed entering a city chimney in Fredericton, New Brunswick, during a monitoring event conducted by Birds Canada.
- This influx occurred amid a long-term decline of about 90 per cent in chimney swift numbers since the 1970s caused by habitat loss, climate change, and pesticide use.
- Chimney swifts breed throughout a broad range in Canada from Saskatchewan to Nova Scotia and migrate to South America for the winter, depending on flying insects for food—a resource that has been declining due to various environmental challenges.
- As of 2023, estimates place the number of mature chimney swifts in Canada between 20,000 and 70,000 birds, with experts noting that these birds face multiple threats that endanger their continued survival.
- The notable count in Fredericton suggests some hope for this endangered species whose conservation aims to stabilize population numbers by 2033 to 2043 and halt declines within 10 years.
