American Bullfrog Rana Catesbeiana
The American Bullfrog is native to North America. During the mating season, which occurs from May to July, the presence of bullfrogs in a pond or lake can be heard from some distance, as male bullfrogs are acoustically very active during this period.

How to Identify
At first sight, a bullfrog and a green frog are not easy to distinguish. I examine the crest that starts above the eye and extends around the eardrum, leading to the front legs. In the case of a green frog, this crest runs along the back to the hind legs. Another characteristic is the size of the tympanum, which is larger than the eye.
Where and When to Spot
In ponds around Montreal from late spring to early autumn, I observe them less frequently than green frogs. Typically, I spot them remaining motionless in the shallow water amidst the reeds along the pond's shore.
