Mr. G. H. Gurney on 
170. Pelecanus oxqcrotalus. White Pelican. 
Pelec anus onocrotalus Gmel. 
Iris deep hazel-red; base of upper and lower mandible 
deep slate-coloured; sides of upper mandible light yellow 
with streaks of red, edge bright red, tip coral-red; pouch 
gamboge-yellow. 
There were two or three large flocks of this Pelican on 
Lake Naivasha. They were extremely wary and shy, but, 
by hiding up in the thick papyrus-reeds near a sandbank 
on which they sat, I was able to bag one with a rifle. Every 
evening they would soar in a long straggling line to an 
immense height in the air. The pouch and stomach of the 
one which 1 shot were empty. 
There was another smaller species of Pelican on the lake 
and some Flamingos ; but I was not able to shoot specimens 
of either of them, and could not determine to what species 
they belonged. 
171. Leptoptilus crtjmeniferus. African Marabout. 
Leptoptilus crumeniferus Lath. 
Bill dirty green; legs black. 
It was always a source of interest to me to watch the 
Marabouts assembling when I had shot a beast. The 
first tiny black specks which appeared in the sky would 
generally turn out to be these great Storks ; the Vultures 
came later. And then, again, in the evening we watched them 
standing like sentinels on the tops of the trees, gazing at the 
now whitened skeleton beneath them. The settlers shoot 
numbers of them for the sake of their feathers. 
172. Scopus umbretta. Hammerhead Stork. 
Scopus umbretta (Gmel.). 
Iris brown ; bill and legs black. 
A nest of this species, which we found in a small mimosa- 
tree at Kallima Theki, was an immense structure of sticks, 
measuring very nearly six feet across. Several of the 
Hammerheads that I shot contained in their stomachs small 
spotted frogs. 
173. Ardea purpurea. Purple Heron. 
Ardea purpurea Linn.
