NOTES ON THE BIRDS OF UPPER ASSAM. 245 



Descends the gorges of the rivers on the north frontier, frequenting 

 the forest growth wherever the sun can penetrate to what patches the 

 surrounding rocks give its rays access. Beni, Abor-Miri hills, Dejoo Gorge, 

 Subansiri Gorge. 



Iris pale stone yellow (naples yellow) ; bill upper mandible and tip of 

 lower mandible blackish horny ; lower mandible greenish horny at base ; 

 tarsus greenish yellow ; soles yellow. 



69. Cnniger fiaveolus (Gould.) [263]. — White-throated Bulbul. 



Very plentiful throughout the plains. A noisy vivacious Bulbul, found 

 in parties in forest. 



70. Hypsipetes psaroides, Vig. [269]. — Himalayan Black Bulbul. 



A hill species. Occurs sporadically in the plains during the cold season. 

 This Bulbul no doubt wanders about the country in parties when the 

 different fruits are ripe and flowers of their favourite trees are in bloom. 

 Simal (^Bombax inalabai-icum) when in flower prove a great attraction. 



Rungagora (Plains), 20-3-04, $ ; Dejoo R., 26-4-03, S ; Dejoo (base of 

 hills), 15-2-09*, a party of a dozen or thereabouts and 19-2-09*, a party of 

 twenty to thirty. 



February is a month for local migration with some of the Bulbuls. 



71. Hemixus flavala, Hodgs. [272]. — Brown-eared Bulbul. 



Sparingly distributed in the plains. Margherita, Panitola, Dejoo, 

 Panchnoi Gorge, Beni. 



In parties in February. A forest Bulbul, not as plentiful as C. flaveolus. 



72. Hemixus maclellandi (Horsf.) [275].^ — Maclellands' Bulbul. 



Plentiful in the Abor-Miri hills. One of the noisiest birds around our 

 camp. A single secured at foot of hills in North Lakhimpur, Derpai 31-1-06, J ; 

 its loud notes attracted my attention. 



Iris sienna brown ; bill : upper mandible horny black ; lower mandible 

 pale horny ; tarsus pale brownish horny. 



78. Molpastes bengalensis (Blyth.) [282J. — The Bengal Red-vented Bulbul. 



A common specie throughout the whole district. A familiar bird every- 

 where excepting in heavy forest. Odd pairs seen at 4,000' in the Abor-Miri 

 hills on the north frontier. Dr. Falkiner had a partial albino specimen in 

 his collection secured at Kharjan. 



74 Otocompsa emeria emeria (L.) [288]. — The Bengal Red-whiskered Bulbul. 

 Equally as common as ilf. iew^^aZewsis with a similar distribution. Found 



also in heavy forest frequenting the topmost branches of high trees in 

 parties of a score or so during the cold season. 



75 Otocompsa flaviventris (Tick.) [290]. — The Black-crested YellowBulbul. 

 Occurs at the base of the hills plentifully. The farthest distance into the 



plains in North Lakhimpur that I have met with this Bulbul is Laluk, 

 1-3-10, although in Lower Assam I have obtained it at Gauhati on the 

 Bramapootra, 12-2-11, S- 



76. Sitta cinnamoventris, Blyth. [316]. — The Cinnamon-bellied Nuthatch. 

 Distributed from the base of the hills and over the watershed, on the 



north frontier. Failed to meet with it in the plains. Margherita, Grandi- 

 tola (Subansiri Gorge). Runganuddie Gorge. Beni (Abor-Miri hills). 



77. Sitta frontalis, Horsf. [325].— The Velvet-fronted Blue Nuthatch. 

 Throughout the plains, very partial to light forest growth and similar 



jungle in the more open beds of the hill rivers. A pair often seen in com- 

 pany with various Phylloscopi, &c.
