The Western Leopard Toad is an endangered species. It lives in Cape Town and breeds in a few short weeks in August/September each year.
The toads migrate to suitable ponds to mate and can cover fairly large distances in an evening. Living in an urban environment leaves them vulnerable to getting squashed by vehicles as they cross roads. It is not difficult to hear if the toads are busy breeding as they make quite a noise.
If you have breeding toads near you please keep an eye out. Visit http://www.leopardtoad.co.za for more information on the toads.
