For many residents of Lambton County, the beginning of spring is often associated with the return of the Tundra Swans. Once the Tundra Swans start to arrive spring is not far behind.

Return of the Swans

We cannot predict exactly when the swans will be in the area, but once they have been sighted in the area we will be celebrating with special programming at Lambton Heritage Museum! Check out our migration calendar for daily updates about how many swans have been spotted in the area. While you are visiting the swans on the Thedford Bog, come by the museum for great exhibits and excellent family activities, including:

  • Discovering the story behind the Thedford Bog
  • Learning about the Tundra Swan’s migration story
  • Testing your knowledge with an interactive quiz
  • Enjoying craft time with step-by-step instructions on folding an origami swan

During March Break, we will be providing access to Makerspace equipment from Lambton County Library. Bring your school age children to try their hands at a button maker or programming an ozobot, a pocket-sized robot. This special programming will be available March 16-20 from 10:00 am – 2:00 pm.

In a good year, there may be 15,000 individual birds resting on the bog, attracted by the melt water of spring and the remnants of the prior year’s corn crop. The first sound to be heard is the soft hoo-hoo-hoo, as the Tundra Swans glide effortlessly down to feed on flooded fields that mark the bottom of old Lake Smith.

The Lambton Shores area is fortunate to have a natural ‘staging’ place for the tundra swans behind the Lambton Heritage Museum property. This land is locally known as the Thedford Bog. Before it was drained for farming, this huge wetland was a stop-over for migrating birds. Each spring the fields continue to flood and the corn and bean stubble from the previous year’s harvest provides food for the traveling waterfowl. Depending on weather and field conditions, visitors can sometimes see thousands of swans, ducks and geese in their natural habitat. It is always best to call ahead or check the website as the swans can arrive as early as mid-February or as late as mid-March.

One of the best places to view the swans is behind the museum along Greenway and Goosemarsh Roads. Bring your binoculars as the swans are sometimes a good distance back from the road.
