You're extremely lucky. After the buffalo died and was fully eaten animals have pretty much disappeared as the rain started coming down and they don't need the watering hole as much anymore. I've been watching for many hours at an end over the last couple of days and not seen much. Today was good however, mixed with Pete's Pond streaming camera I managed to see impalas, kudu, ibis, egyptian geese, jackal and some unidentified birds. Still, even on the days I didn't see anything (Apart from Egyp & Tian the egyptian geese which can be seen daily) I still enjoyed watching and hearing the birds/frogs make their noise.
