When doing surveys in the summer in central Ontario, it is not uncommon to hear Mink Frogs clucking away in large wetlands. Mink Frogs are summer breeders, filling the air with their calls by day while Gray Treefrogs take over for the night shift.
Our Sudbury site has an abundance of Mink Frogs, and so I snapped a few photos on the rare occasion that I had my camera with me in the field.

For comparison, here is a photo of a Green Frog from last spring. Note the Mink Frog's more pronounced blotches on its dorsum. Additionally, the Green Frog has dark bands around the hindlimbs, while the Mink Frog has broken bands, if it has any at all. Green Frogs have a more pronounced dorsolateral ridge; the raised line running from behind their tympanum (ear) down towards their hindlimbs.
