The Giant Rain Frog (Breviceps gibbosus)

I came across these two Giant Rain Frogs in our vegetable garden in the morning after a rainy night in October. Both frogs were calling right next to each other in the open, which is unusual (usually they call from cover or at the entrances of their burrows. I wonder if this was some sort of territorial interaction between males, although no physical contest was observed. As seen in the footage, the one frog moves away from the other (possibly admitting defeat?), but also heads straight towards me with the camera. I wonder if he was investigating or it was was chance that it was the direction he took. Eventually, once the 'defeated' male is a couple metres away, he begins to call again. The other male continues to call but eventually disappears into the nearby vegetation, and the 'defeated male also moves back to the original spot and also returns to cover (at the end of the footage). The Giant (or Cape) Rain Frog occurs around Cape Town, and is found in some gardens that are not too disturbed or unnatural. They require no water-bodies for breeding and can attain quite dense populations, as in our garden. Their characteristic chorus is common in the wet cape winter, and often begins during rain or watering of the garden.
