American Bullfrog

The American Bullfrog (Lithobates catesbeianus) was introduced to British Columbia in the early 1900s when it was brought from eastern North America for frog farming. The farming did not go well, as there was not a big market for frogs legs, and they were either released or escaped into the wild. They are the largest frog in North America and a highly invasive species. They consume native frogs and other amphibians as well as birds, fish and invertebrates and can cause the local extinction of native species. In the spring and summer males form large breeding groups and sit in the water, inflating themselves and calling for females. They are found in the Lower Mainland, Fraser Valley, south and central Vancouver Island and are currently expanding their range to places including the south Okanagan.
