The plains all the way from Ngorongoro to Seronera have received some heavy rains in the last couple of days, and we would expect the calving to get into full swing brought on by the burst of fresh grass which is about to come out after those rains. The big herds are spread out between Kusini, over the plains do Ndutu and the woodlands, Hidden Valley and some are reaching as far over as the Gol Mountains.
