Okavanga Delta, Botswana.
The first time I saw one of those in 25 Safaris.
Congrats on the find. I’ve never heard of the marsh mongoose. Is it different from the water mongoose (which I’ve only seen from a distance at night)?
Yes, a different species. Water Mongooses are relatively common in the right habitat. And indeed mostly nocturnal. I’ve seen them regularly, but I never managed to get a decent photo.
