Tundra swans return to Lambton County for annual spring migration

The arrival of thousands of Tundra swans at the Thedford Bog marks the start of a massive 6,000-kilometre journey and a unique opportunity for Sarnia-Lambton residents to witness one of the region’s most significant natural spectacles.

Spring has officially arrived in Lambton County with the first sightings of Tundra swans at the Thedford Bog. These magnificent birds are beginning their annual stopover behind the Lambton Heritage Museum as they trek between Chesapeake Bay and the Canadian Arctic.

The migration is a massive 6,000-kilometre loop, and the local bog serves as a vital resting and feeding ground. On peak days, as many as 15,000 swans can be seen gathering in the meltwater to feed on the remains of the previous year’s corn crop.

Because the number of birds fluctuates daily based on weather and field conditions, residents are encouraged to check for updates before heading out. The museum provides daily estimates to help locals time their visit for the best viewing experience.

For those looking to see the birds up close, the following resources are available:

The Lambton Heritage Museum is also hosting a "Return of the Swans" feature exhibit until April 4. The exhibit explores the history of the Thedford Bog and the biology of the swans through various activities and displays.

The museum is open Wednesdays, Fridays, and Saturdays from 11:00 a.m. to 4:00 p.m., with extended hours on Thursdays until 8:30 p.m. Admission is $5 for adults, $4 for seniors and students, and $3 for children.

This annual event highlights the importance of our local ecosystems in supporting international wildlife corridors. It serves as a reminder of the deep connection between our local geography and the broader natural world. Visit heritagemuseum.ca for additional resources.
