THE BIRDS OF THE LUCKNOW CIVIL DIVISION. 19 
It breeds from February to May, making its nest invariably in 
holes in river banks, &c., while its daily vocation appears 
to consist of an incessant whirling to and fro, relieved by 
frequent visits to its subterranean quarters. During May 
last I took many eggs from nests in the banks of the Goomti, 
of which 0°70 by 0°48 inches is the average measurement 
of ten. 
100.—Cypsellus affinis, J. #. Gr. 
The Common Indian or White-rumped Swift is very abundant 
about Lucknow and in all suitable localities. 
It breeds, I think, twice a year, as I have seen inhabited nests 
as early as February and as late as August. The inside of the 
roof of the Alumbagh Gateway is usually covered with nests, 
semi-globularinshapeand closely packed together, so much so that 
if you took one down half a dozen others would come along 
with it. Nests are equally abundant about deserted buildings, 
&e.,in and around Lucknow, while solitary pairs not unfrequent- 
ly breed in bungalow verandahs. A pair that took up their 
quarters in the verandah of the house I reside in were so 
fond of twittering at all hours of the night that 1 came to 
regard them as a nuisance and banished them from the 
premises. 
Average measurement of six eggs, 0°90 by 0°57 inches, 
102.—Cypsellus batassiensis, J. #. Gr. 
The Palm Swift appears to be a strictly rural bird, rarely 
found, except in the immediate vicinity of palm trees, those on 
the banks of jhils and streams seemingly preferred. It is a 
permanent resident. 
109.—Caprimulgus albonotatus, Tick. 
15th December, Male.—Length, 12°8; expanse, 25°; wing, 
8°45 ; tail, 6-8; tarsus, 0°83; bill, from gape, 1°45. Bill black ; 
legs and feet vinaceous brown. 
The Large Indian Nightjar is fairly common and a permanent 
resident. As many as twenty may sometimes be flushed'‘in some 
favourite spot, but, as a rule, it is found singly or in pairs, 
generally in thick brushwood under the shade of trees, but it is 
also very partial to bamboo brakes and thick dhak jungle. 
When flushed, it usually flies but a short distance and squats 
again, either on the ground or on the low and spacious arm of 
some tree. Occasionally it may be found resting during the day 
high up in thick bamboos, and in clumps of these it probably 
breeds, though I have never found its nest. But in whatever 
tangled thickets it may rest for the day, it sallies forth at dusk
