L'une des plus grandes couleuvres de l'Ontario, la couleuvre agile bleue est une couleuvre fin bleu-gris avec un masque noir autour des yeux et un ventre blanc. Atteignant presque 2 mètres de long, elle se nourrit de rongeurs, d'insectes, d'oiseaux et d'autres serpents.
Blue Racer (Coluber constrictor foxii)
Rapide et craintif envers les humains, le couleuvre bleu est l'un des serpents les plus rares au Canada, avec moins de 400 individus restants dans tout le pays.
Habitat
Aire de répartition
In the U.S, Blue Racers 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 menacés snakes.

Rétablissement
Actions de rétablissement recommandées
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.
