Every now and then I catch something else besides an African Pouched Rat. It's not what I was aiming to catch, but I am happy nonetheless. Catching predators always gives me great joy.
I'm pretty sure this is a Marsh Mongoose, Atilax paludinosus. It fits the description, looks like the pictures, lives in the distribution area and described habitat. In fact, this field site flanks a ravine. The day before my research assistant saw something big run past him and up a tree. He says it looked like this animal. (Oh, my!)
