352 NOTES ON SOME BIRDS COLLECTED ON THE NILGHIRIS 
fisher which I have doubtfully referred to this species. It 
was probably the same form as that obtained by Mr. Bour- 
dillon in South Travancore.* 
[136.—Ceryle rudis, Lin. The Pied Kingfisher, 
Occurs in South-West Mysore certainly, and I believe in the 
Wynaad also.—A. O. H.] 
140.—Dichoceros cavatus, Shaw. The Great Horn- 
bill. 
This species occurs sparingly in the forests of the slopes 
of the Nilghiris, but is more common in the forests of the 
Wynaad. In the cardamum forests of the Peria Ghat I once 
saw some 50 of these birds all congregated together. Neither 
this species nor the two following ones ascend to the table- 
land of the Nilghiris. I have never seen the present species 
above Burliar, about half-way between Coonoor and the foot 
of the Ghats. 
141.—Hydrocissa coronata, Bodd. The Malabar 
Pied Hornbill. 
Occurs in the evergreen forests of the Wynaad, and ‘the 
slopes of the Nilghiris, usually in small parties, but not un- 
frequently in pairs. It does not ascend the slopes of the hills 
as high even as J. cavatus does. 
145.—Tockus griseus, Lath. The Jungle Grey Horn- 
bill. 
This species occurs through the Wynaad, and all: about 
the base of the hills, but does not ascend their slopes 
that I am aware of. Ihave sometimes found it in pairs, 
and once came across a single one, but this is very rare, 
as it is almost always in small flocks, varying from half 
a dozen to twenty or more individuals, It is an extremely 
noisy bird, the whole flock keeping up an almost incessant 
screaming as they move about feeding, one bird commencing, 
and the others taking up the call in rapid succession. But 
though their presence is easily detected by their call (which 
might be syllablized Kyah, Kyah, Kyah ad lib.); they are so 
exceedin aly shy that it is no easy matter to secure a specimen. 
I have more than once followed a flock about a forest here, 
there, everywhere, for four or five hours at a stretch without 
obtaining a shot. Unlike the other two species of Hornbill, 
ae Vide S. F., 1V., 383. I believe this ought to be separated as a distinct. species.
