Also growing here, though less common, is the toothbrush bush, the stems of which when chewed at the ends make a very serviceable toothbrush. If you are interested in seeing it, ask your guide to point it out and show you its use. In March the white flowers, which have a very sweet smell, can be seen decorating the landscape. Known to nest in tall trees in the Mbalageti valley are Martial Eagles , another of the great birds of prey of the Serengeti, being second in size only to the crowned eagle. This bird, ashy brown above and on the wings, has a distinctive white belly dotted with brownish spots.
Martial eagles are powerful hunters, able to kill game birds, hyraxes and small antelope.
To the south west of the western corridor lies the Ndoha Plain-this area is at present rather inaccessible. It is here that you might see Roan Antelope . These striking animals are rust grey and have prominent black and white facial markings, long ears, and strong heavily ridged, backward sweeping horns. This area is also the main breeding ground in the Park for topi. Baboons and vervet monkey troops are commonly found in the western corridor and in the riverine forest bordering the Grumeti River.
