Renowned wildlife photographer Terry Chettle captured a unique moment at Grimsby Wetlands in early August while photographing a green heron. Unexpectedly, a river otter appeared, engaging in playful behavior with the heron, surprising both Chettle and the bird.
Chettle, a resident of Beamsville, Ont., expressed his surprise at encountering the otter, as they are not commonly seen in the area. When the otter moved to a log and began grooming itself, Chettle took the opportunity to photograph the charming display, which included the otter playfully sticking out its tongue and waving.
During the same outing, Bruce and Laurie Mackenzie, who were exploring the wetland, crossed paths with Chettle, who pointed out the otter to them. Bruce Mackenzie noted the rarity of the otter sighting, mentioning that it was the first such sighting near the wetlands in recent memory on August 3. Subsequently, there have been no reports of otter sightings in the area.
Managed by the Hamilton Naturalists’ Club, the Grimsby Wetlands cover approximately 12 hectares on the South Shore of Lake Ontario. Bruce Mackenzie, who is involved with the club as the project manager for the wetlands, highlighted the significance of the otter sighting as a positive indication of habitat restoration and improved water quality. The wetlands have previously hosted rare species like least bitterns, underscoring their importance for biodiversity conservation.
Laura Timms, a program manager at Credit Valley Conservation, emphasized the remarkable recovery of river otter populations, attributing it to conservation efforts in the Golden Horseshoe region. Timms noted a noticeable increase in documented otter sightings, including instances of otters giving birth to pups at conservation areas like Rattray Marsh and Jim Tovey Lakeview.
While river otter populations faced significant declines in the 19th century due to hunting, habitat destruction, and poor water quality, efforts to restore ecosystems have led to their resurgence across North America. Timms stressed the need to continue conservation work to protect habitats like wetlands, essential for supporting diverse species and mitigating environmental challenges like flooding and carbon storage.
River otters, which can grow up to 1.4 meters in length and weigh between five to 14 kilograms, are carnivores that inhabit rivers, lakes, and creeks. They feed on fish, clams, insects, and other aquatic creatures, contributing to the ecological balance of aquatic ecosystems. Timms urged ongoing efforts to safeguard habitats to ensure the thriving of various species and to replicate success stories like the recovery of otter populations.
