Wildlife enthusiast Terry Chettle captured a fascinating encounter between a green heron and a river otter at Grimsby Wetlands in early August. Chettle, a resident of Beamsville, Ont., was surprised by the otter’s presence as they are not commonly seen in the area. The otter, after moving to a log and indulging in some preening, put on a playful display for Chettle by sticking out its tongue and waving.
During the same outing, Bruce and Laurie Mackenzie, who were strolling in the wetland, met Chettle, who pointed out the otter to them. Bruce Mackenzie noted the rarity of the sighting, mentioning that it was possibly the first otter sighting near the wetlands in recent memory. He added that no one has reported seeing the otter since that particular weekend.
The wetlands, previously a sewage storage site for Niagara Region, are now managed by the Hamilton Naturalists’ Club, covering approximately 12 hectares on the South Shore of Lake Ontario. The area has been transformed into a popular destination for hiking and bird-watching. Bruce Mackenzie, who works with the naturalists club, expressed satisfaction with the otter sighting, emphasizing the positive impact of habitat restoration and improved water quality on the local ecosystem.
River otters, once on the decline due to hunting, habitat destruction, and poor water quality in the 1800s, are now making a comeback in North America. Laura Timms, a program manager at Credit Valley Conservation, highlighted the success of otter conservation efforts. The authority has observed a growing trend in otter sightings, with documented reports becoming more frequent, including instances of otters giving birth to pups at conservation areas such as Rattray Marsh and Jim Tovey Lakeview.
Despite the positive otter population resurgence, Timms emphasized the need for ongoing efforts to restore and protect various habitats to ensure the thriving of all species. Wetlands, in particular, play a crucial role in supporting biodiversity, storing carbon, and preventing flooding, making their restoration and conservation essential for the success of diverse wildlife populations.
