The nests are made of dry grass, fern, and leaves, with a 

 few flowering grass-heads and a feather or two, all cemented 

 together by a mucilaginous secretion from the birds' salivary 

 glands. They usually have two entrances, but when under 

 the roof of a cave one side hangs down so as to form a single 

 entrance. 



The eggs are white, and three average '86 x "SQ. 



Chjetura caudacuta. 



During the third week of April, 1907, several pairs were 

 noticed by Mr. J. C. Kershaw hawking for flies in the forest 

 at Howlik. 



Caprimulgus monticola. 



Tliis Nightjar occurs as a winter visitor on the lower 

 parts of the West River, but is rare on the coast. 



At Kwei Hsien, in Kwang Si, birds both mature and 

 immature were plentiful on the plain, and there can be little 

 doubt that they breed there. 



Caprimulgus jotaka. 



The Indian Nightjar is a winter visitor which only occurs 

 between the months of October and April, while a good many 

 pass through on migration. 



As a rule, it appears on its way south from October 12 

 to 26, and on its return journey leaves about April 21 

 or a little earlier. It is to be seen up the West River as 

 well as on the coast, and it has been noted on the small 

 islands between Hong Kong and Macao. 



EUKYSTOMUS CALONYX. 



The Broad-billed Roller passes through on the spring and 

 autumn passages in small numbers, and has been observed 

 in April and May on the foimer, and in September on the 

 latter. A few pairs were seen at Howlik on May 10, but, 

 as a rule, these birds, like so many others, keep to the coast. 

 Its undulating flight is very curious, and is not unlike that 

 of the Green Woodpecker.
