The mink frog is found in weed-choked, sluggish rivers, along marshy shorelines, and in swamps and bogs.
It is most often found in Central Ontario.
Calls are heard in June and July, sounding from a distance like the staccato sound of someone hammering.
Eggs are laid in loose clusters and are attached to submerged vegetation.
Tadpoles spend the winter in the water, and transform in June or July of the following year.
Mink frogs are opportunistic feeders and they will feed amongst floating plants some distance from the shore.

Description of call: The sound of someone hammering in the distance, or the hooves of a galloping horse.
