During the dry season in the Hinterland, from November 
to May, all the Falcons are more plentiful than at other 
periods of the year. This is accounted for by the long grass 
being burnt by the natives after the rains, when the ground, 
being more clear, affords a better opportunity to the Hawks 
for observing their prey.
