Burchell's and Grevy's Zebra 87 



This large zebra lives chiefly in open or sparsely wooded country. 

 Near the Tana it is found in more bushy ground, but it always avoids any- 

 thing like thick bush more than does Burchell's. It is mainly an animal 

 of the arid plains, though it also sometimes frequents bare stony hills, but 

 always in barren country where the grass is short. Burchell's, on the other 

 hand, may be found in all kinds of country, except in dense forests and 

 extensive scrubs where there is no open and no grass at all.

Zebras (of both kinds, I believe) seem to foal about August or 

 September as a rule, though not uniformly, as I have seen a newly-born 

 foal in May. The herds of grevyi are not usually very large, not so large 

 as are sometimes those of burchelli. Of the former, from quite a few 

 individuals up to about twenty, or occasionally perhaps as many as thirty, 

 would be the limit in numbers under ordinary circumstances, whereas much 

 larger troops of Burchell's are sometimes seen — even two or three hundred
