We were delighted this weekend to find dozens of Great Barred Frog Tadpoles in our dam. We noticed them calling at our dam for the first time some months back. While they generally breed in streams, they can adapt and breed in ponds and dams. Obviously they have mated in our dam and hopefully some of the tadpoles with make it to adulthood.
The Frogs of Australia website has a profile of the Great Barred Frog. It has a very distinctive call and can be listened to below.
