IN SAMBALPUR AND ORISSA. 235 
The following birds were met with only in Orissa, and so far 
as my observation has gone, do not extend into Sambalpur :— 
ORISSA. 
208.—Ololygon passerinus, Vahl. 
The Indian Plaintive Cuckoo not improbably extends into 
Sambalpur,* as I have found it in Chota Nagpur, where, how- 
ever, it 1s excessively rare. 
I got one specimen not far from Cuttack. The bird was in 
full adult plumage, and I was struck with the general resem- 
blance it presents to Volvocivora melaschistos—just as Surniculus 
dicruroides resembles, so faras plumage goes, Buchanga albi- 
rictus. From Mr. Hume’s Nests and Eggs it would appear 
that there are no recorded cases of the eggs of either species 
being found in the nests of the species they respectively 
resemble ; but what can be more likely, than that this imita- 
tion subserves the purpose of fascilitating the birds in their 
endeavours to lay their eggs in the nests of the species they 
so resemble. 
452.—Ixos luteolus;, Less. 
The White-browed Bulbul is very abundant in Orissa through- 
out a broad zone in which the vegetation is characterized by 
certain species of plants which are not met with further west. 
These are for the most part thorny shrubs, which often form an 
absolutely impenetrable thicket. These thickets abound in the 
above species, together with Otocompsa emeria. Zanclostomus 
sp. (?) 1s occasionally seen, and of course many other birds. 
Jungle, Pea, and Spurfowl are common in this cover, where 
it is extremely difficult to shoot them. 
The zone extends westwards as far as Ungul and so far is the 
White-browed Bulbul to be found, but not beyond. So defined 
is its limit here that I think it probable that I was in error in 
inserting it in the Chota Nagpur list, since Colonel Tickell’s 
specimen was obtained in Midnapur, and it is possible that the 
species does not extend so far west as Manbhum. 
695.—Ploceus manyar, Horsf. 
The Striated Weaver bird was very common in the vicinity 
of the Mahanadi above Cuttack during last April. Whether 
it is a permanent resident or not I cannot say. Flocks num- 
bering several thousands were several times seen. 
Carpophaga enea, Linn. 
The Imperial Pigeon is excessively common throughout 
the hilly jungles of the western states of Orissa. I shot it in 
* Itis very common in the adjoining district of Raipur, but I do not seem to have 
received it as yet from Sambalpur.—Eb., S, F
