It is no uncommon sight to see one buck with twenty or thirty females, and it is probably due to the fact that hunters try to get the male specimens as trophies that accounts for the vast preponderance of females in the various antelope herds.

The impalla is seen along the railroad and in enormous numbers out along the Thika Thika and Tana Rivers.

There are also many up in the Rift Valley and doubtless in other sections.

From my own experience and observation they were most abundant on the Tana River.
[Drawing: _Impalla Buck and Lady Friends_] The wildebeest, or gnu, is found on the Athi Plains and northward along the Athi River and the Thika Thika.

One need never travel more than two hours' drive or walk from Nairobi to see wildebeest, but it's a different thing to get them.
