NOTES ON THE BIRDS OF UPPER ASSAM. 565 



289. Apus affinis afflrds, Gray. [1073]. — The Common Indian Swift. 



Oypselus affinis, Blanford, F. B. I., Vol. iii., p. 168. 



Specimens collected. Joyhing, 12-2-05, 6,6, agree with East Nepal 

 birds. Length of wing, *5"4" and 5'2", outer retrices '2 longer than 

 middle pair and are referable more to the typical form, trvisting to these 

 measurements than to A. a. subfurcatiis. Some records of Large Swifts seen 

 as follows may have been A. pacifus. Rungagora, 1-6-02, single bird 

 hawking for insects at evening over the Dibru R. in company with Sand 

 Martins. I noticed a peculiar flapping of the wings on flight and the 

 marked difl"erence between the length of primaries and secondaries. It 

 passed repeatedly within a few feet of my head and constantly was 

 dipping into the water. 



Dejoo, common, July and August. Rajghur, 27-8-10, numbers hawking 

 within gunshot range, bright morning, heavy rain clouds over the hills. 



Dejoo, 19-4-07*; Silonibari, 2-9-11.* Two large Swifts flying fairly high 

 during heavy rain, low temperature, several seen also on 26-9-11*. 



290. TacJiornis batassiensis batassiensis (Gray) [1075]. — The Palm Swift. 

 Rungagora, 16-1-02*, 9-4-03, d; Dejoo, 1-1-05, $, 2—4-7-04, 3 d J. 

 These Swifts attach their nests to the large overhanging leaves of the 



Toko Palm {Lioistona jenkinsiaua) in compounds, very frequently almost 

 within hand reach. Other favourite positions are the projecting eaves of the 

 thatched roofs of the bungalows. The Rungagora bungalow was in much 

 request in this respect. At evening they sally out in quest of food with 

 lively twitterings and arrowy flight. 



291. Collocalia unicolor fuciphayci (Thunb.) [1082]. — The Himalayan 



Swiftlet. 



Collocalia brevirostris, Blanford, F. B. I., Vol. iii., p. 177. 

 Dejoo, North Lakhimpur, 4-3-10, several procured during a dull after- 

 noon, numbers were hawking for food at high and low altitudes. 



292. Caprimulgus macrowus ambiguus, Hart. [1093, part]. 



Caprimulgus macrurus, Blanford, F, B. I., Vol. iii., p. 188, 

 Rungagora, 8-11-01, 3 $ $ ; Dejoo, 21-7-07, 6 ; 12-9-08, 6 ; 24-6-10, 

 2 juv.; 5-11-08, 6, shot at 12-30 p.m. midnight in the centre of the 

 clean trodden path which had its alignment past my bungalow at full moon, 

 almost as daylight. 



Rungagora, September 1902, one night during this month whilst near 

 Kamptigwali on my walk home from Dinjan a nightjar alighted on one 

 of the fence posts, on the high road allowing me to approach within two 

 arms' lengths before taking flight. Quite a common occurrence to have them 

 flying about the bungalow com-pound after sunset. I have seen them dash 

 under the verandah porch, very frequently alight a few paces in front of one 

 on the path and as one strolls along flap leisurely to another position 

 a few paces farther away, again to be disturbed and act in a similar 

 manner. 



293. Caprimulgus indicus indicm, Latham. [1095.] — The Jungle Nightjar. 

 Dejoo, 12-2-05, S , single record only. 



Lyncornis ce?-viniceps possibly has been overlooked. I have a note against 

 this Nightjar. First weeks in September, Dejoo, North Lakhimpur ; but 

 as no specimens were secured this record lacks svibstantiation. 



294. BatracJiostomus Tiodgsoni hodgsoni (G. R. Gray) [1097.]— Hodgson's 



Frogmouth. 

 Dejoo, North Lakhimpur, 1-1-05, $. This bird was brought in alive 

 from the hills by Daphlas.
