Ammoperdix heyi Shelley, p. 222. 
This handsome little Rock-Partridge has been met with in 
the Wadi Hof near Helwan, which is the only locality I at 
present know of in the Province for the bird. I have an 
adult male which I shot there on the 31st of December, 
1908. This example lacks the white forehead and lores 
which are present in most adult male specimens of A. heyi 
that I have examined, but in this respect it agrees with a 
specimen from Palestine in the Tring Museum. 
Ammoperdix cholmleyi was described by Mr. Ogilvie-Grant 
as distinguishable from A. heyi by being darker above and 
having no white on the forebead and lores. This is borne 
out by most specimens ; but although I have not yet seen a 
specimen of A. cholmleyi with a white forehead, I have seen 
several males of A. heyi } besides the two previously mentioned, 
which have no white on the forehead and lores. Thus it 
seems that Ammoperdix cholmleyi is only to be distinguished 
from A. heyi by the darker coloration of the upper parts, and 
this I find to be the case on examination of the types of 
A. cholmleyi . In the latter, moreover, the rump is more 
distinctly barred than in A. heyi. 
In the typical form, A. heyi , the upper parts, mantle, 
wing-coverts, and scapulars are sandy buff with a pinkish 
tinge. The lores and forehead are with or without white. 
In A. cholmleyi the upper parts are vinaceous and the lower 
back, rump, and upper tail-coverts more distinctly barred. 
The forehead and lores are not white. It should be pointed out 
that specimens of these two forms are by no means plentiful 
in collections and that their range is by no means clearly 
worked out. It would seem that both A. heyi heyi and 
A. h. cholmleyi occur in Egypt, but “ Egypt v is a somewhat 
elastic term for a locality, and birds labelled “ Egypt ” are 
practically useless unless we know the exact range of the 
species or subspecies in question. 
Specimens of Hey's Partridge are very difficult to obtain, 
as they trust more to their running powers than to flight, 
and invariably run away up the sides of the valleys, while 
always keeping just out of gunshot.
