Every spring, individuals of all ages depart Saskatoon to become citizen scientists on the Mary Houston Bluebird Trail.
The trail, established in 1969, stretches about 80 kilometers from slightly south of Langham, Sask. to just north of Hanley, Sask.
At intervals of 400 meters, small birdhouses are attached to fences along the trail.
These 250 nest boxes serve as surrogate hollow trees, offering crucial habitats for migrating birds under the watchful eyes of volunteers.
Greg Fenty, a biologist and retired environmental educator, leads this volunteer initiative for the Saskatoon Young Naturalists under the Saskatoon Nature Society.
“The Bluebird Trail consists of a series of nest boxes arranged along a country road, monitored for bluebirds and tree swallows to study their breeding success and lifespan,” explained Fenty.
This data aids researchers in tracking changes in bluebird and tree swallow populations over time.
Historically, bluebird populations declined until the 1950s due to habitat loss and pesticide usage. Subsequently, conservation and monitoring efforts intensified.
Bluebirds can live up to eight years on average and migrate over 3,000 kilometers southward.
The Mary Houston Bluebird Trail attracts families each spring to learn about conservation by monitoring young birds.
Volunteers are taught by Fenty, with a scientific permit from the Canadian Wildlife Service, on proper bird handling, banding, and species identification techniques.
