304 Mr. C. F. M. Swynnerton on the 
153. Gyps xotsir. Kolbe’s Griffon. 
I saw numbers of these birds in Gunye’s country in 
1900, and they appear to be extremely abundant throughout 
the low veld, where the number of bucks killed by wild 
animals ensures a constant food-supply. Vultures are seldom 
or never seen on the highlands, and even during the 
recent deadly outbreak of African coast-fever, when the 
cattle were dying by hundreds, the Ravens were the only 
birds which came to feast on the carcases. One of these 
Vultures, gorged and brought to bay, once attempted to 
attack me. 
154. SERPENTARIUS SECRETARIUS. Secretary-Bird. 
I have frequently observed this bird in pairs on the open 
hills covered with short grass, which surround Melsetter. 
155. Puatacrocorax Lucipus. White-breasted Duiker. 
Fairly plentiful on all the larger streams. 
156. Crconra ALBA. White Stork. 
In November a number of these birds arrived with a swarm 
of locusts, and remained for a considerable time stalking 
about my cultivated lands and devouring the locusts which 
were covering the ground. ‘They were very tame, allowing 
me to approach within thirty yards, and then merely 
walking away at the same pace as myself and occasionally 
looking back while continuing their feast. 
157. Ciconra nicRA. Black Stork. 
I have seen this “ Locust-bird,” as the Storks are locally 
called, on several occasions each winter for the past three 
years, but it usually passes over at a great height. Last 
October, however, in company with Mr. Marshall, I had an 
opportunity, for the first time, of observing these birds at 
closer range, as they flapped slowly backwards and forwards 
through a large swarm of locusts which was settling on 
the outskirts of Chirinda. On my attempting to procure 
a specimen, they did not make off at once, but rose gradually 
in ever-widening circles until they had reached the required 
elevation.
