American Bullfrog - Rana Catesbeiana

The American Bullfrog is native to North America. During mating season, 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 mating season.

Where & When to Spot

In ponds around Montreal late spring till early autumn. I see them more rarely than green frogs, usually I spot them staying still in the shallow water in reed along the shore of a pond.

How to Identify

On first sight, a bullfrog and green frog are not easy to distinguish. I look at the crest starting above the eye and extending around the eardrum leading to the front legs. In case of a green frog, this crest leads along the back to the back legs.
