One of Ontario’s largest snakes, blue racers are slender blue-grey snakes with a black mask around the eyes and white undersides. Reaching almost 2 metres in length, they prey on rodents, insects, birds, and other snakes.
Blue racers prefer semi-open habitats such as savannahs, alvars, grasslands, fields and open woodlands during the active season (April to October). Winters are spent in communal hibernation sites such as burrows or rock crevasses.
In the U.S, blue facers are found in several northern states, including Illinois, Indiana, Iowa, Michigan, Ohio, and Wisconsin. In recent decades their range in Canada has shrunk from several areas on the mainland of Southern Ontario to one isolated population on Pelee Island, making them one of the province’s most endangered snakes.
Although habitat loss is the primary threat to the Canadian blue racer population, individuals may also fall victim to road mortality, agricultural equipment, and intentional human persecution.
The Blue Racer Recovery Strategy cites hibernation and nesting locations as the areas most important to the species’ continued survival. In recent years, efforts have been made to protect and restore blue racer habitat on Pelee Island, with tree removal and a prescribed burn taking place to maintain savannah conditions. Surveys to estimate the population size of blue racers on Pelee Island are currently being carried out (2020-2022) to update the estimate done from 2000-2002, along with recent genetic studies to determine the long-term sustainability of the Canadian blue racer population.
Find out how Wildlife Preservation Canada helps save Canada’s reptiles and amphibians, including blue racers, and how you can make a difference.
Rosie Heffernan, Wildlife Preservation Canada’s 33rd Canada’s New Noah, gives you an inside look at how this one-of-a-kind program equips the next generation of conservation biologists with skills they can’t learn anywhere else.
If you’re curious about how we can safeguard Canada’s biodiversity, this session highlights why investing in training today is critical for protecting wildlife tomorrow.
