Perhaps a useless update but I am in Kogatende at the moment and there is nothing here. We have too many conflicting reports from the ground at the moment. Some say they are a little bit west of Lobo others a distance NE of Kogatende and some even say they are in the Mara.
From the air, we haven't seen them since they left Fort Ikoma. There are just herds of Zebra around Grumeti and Sasakwa. Will keep you posted on the whereabouts when we find the 1.6 MILLION wildebeests!
