A. Assam. Presented by J. McClelland, Esq. 
h. Drawing. From Dr. F. (B.) Hamilton's Collection. 
" This bird inhabits Bengal at all seasons, and is a nocturnal bird, 
appearing at sunset, and going to rest at sunrise. It builds its nest 
in the fronds of the Tal (Borassus Jlcibelliformis, Linn.). The Ben- 
galee name signifies a bird resembling wind, and is bestowed on this 
species on account of its swift flight." — (Dr. F. (B.) Hamilton, MS. 
I. p. 82.) 
Captain Tickell remarks : " The eggs are f x (immensely large 
for such a bird), rather blunt, white, with rather large spots of deep 
claret-brown, most numerous at the big end. July." — (Journ. A. S. 
Beng. XVII. p. 302.) 
Mr. Jerdon also remarks : " This species is common in all the 
districts of India, except on the bare table-land, where it is rare. As 
its name implies, it frequents groves of palms, especially the Palmyra 
{Borassus JlabelUformis) , and does not in general fly to any distance 
from them."— (Madr. Journ. L. S. XI. p. 236.) 
Mr. Blyth also states : This bird " mainly affects rural districts, 
building its nests within the fronds of the fan-leaved palms, some- 
times twenty or thirty pairs of them associating in those of a single 
tree ; while it is also rare to meet with one of the same palms clus- 
tered with the pensile nests of the Baya {Ploceus pJiilippensis) , that 
does not also harbour two or three pairs of this elegant little Palm 
Swift."— (Journ. A. S. Beng. XI. p. 889.)
