Such massive animals, who can be so thunderous when they find the need, can also be so incredibly quiet. This group approached us and drank from the channel just a few meters away, leaving us in awe.

I'd reconciled myself to not having the territorial call of the most iconic predator on tape. We would hear them in the distance often, terrifyingly, but always in the distance, and passing through areas so quickly didn't give much opportunity to plan ahead. My last night, on Chief's Island by Hippo Hide, I heard one briefly, and fell asleep with the mic pointed in its direction. I checked the recording in the morning, and it included this. Some freaked out baboons establish the mood.

A crocodile carcass on the floodplain was presumably the result of an encounter with a defensive elephant. Not many animals seemed interested in it apart from a bevy of flies (and us).

Night sounds around my tent including some very small and very large animals.

Antiphonal call that is ubiquitous in the delta, finally got a reasonably clear recording chasing them around a termite island.

Beautiful call by this bird couple. Google "antiphonal birdsong". Really wanted to get this recording to send to my partner whom I was missing. She made it her ringtone.

One of the many times where I was recording something from inside my tent with no idea what I was hearing. There was much activity in the channel next to me throughout the night, some of it probably not so benign. But the team agreed this is jumping catfish. The breeze through the palms is a definite soundmark of these islands.

The rhythm of traveling by mekoro with the interplay between water, air, ngashi (pole), and reeds, can be very meditative and beautiful (when there is enough water and clear passage). I don't want to forget this pulse.

Poling our mekoro past a small termite island, we heard a fuss -- vervet monkeys. Pete and Tom both speculated it was alarm calls for a nearby leopard.

We were inadvertently about to camp between members of a group of elephants on a narrow strip of island. This display (ears, stomping, trumpets) let us know in no uncertain terms that we should leave the passage between them open.
