Water buffalo at the watering hole at 3am their time. There were three of them and one went for a long soak in the water. He had a hard time getting out, thrashing and grunting, getting part way out and sliding back in again. They made a great deal of noise, snorting at each other, drinking and splashing. I couldn't post here while it was happening because I could only tear myself away long enough to check on the Africam forum - that's where I learned they were Cape Buffalo. I kept thinking that's what they looked like, but it's very hard to see details of animals at night and I didn't know they moved around at night.

The Africam forum is wonderful with many knowledgeable people. They post the names of all the birds calling, and the animal sounds when you can't see them.
