The population of Barn Swallows has dwindled by 70 per cent in the last 20 years around the world, and researchers in Canada say it is worse here than anywhere else.
Reporter Linda Aylesworth was took a close look at the Barn Swallows on Thursday and saw first-hand how they are struggling.
The Barn Swallow is an aerial insectivore, meaning it catches insects for food while in-flight, and aerial insectivores are in trouble all over the world.
One reason could be the use of pesticides, but other problems include light pollution, climate change, and temperature and precipitation extremes. With all the rain in B.C. in the past few months, it is no wonder the insect population is suffering. Flying insects don’t fly and Barn Swallows don’t eat.
The loss of nesting sites is also a concern, as Barn Swallows prefer barns and stables, especially old wooden structures. However, those buildings are also in decline.
Experts believe the decline of the Barn Swallow is an indication that our ecosystem might no longer be able to support species such as Finches or Night Hawks and other endangered species. More research is needed as well as laws that enforce the changes needed to save these and other species.
