lt8 THE FOOD OF BIRDS IN INDIA. 



1081-1085. Collocalia. " This gsnus contains birds gener- 

 ally designated Swiftlets by Indian oinithologists, some of which 

 b iild the edible nests of commerce. Hume showed that in the 

 Andamans the pure white nests are always made by one species, 

 C. francica, whilst other species use extraneous substances such 

 as grass and feathers cemented together by the inspissated saliva, 

 and their nests are consequently less valuable, or in some kinds, 

 not worth collecting. During the day the birds hunt about for 

 insects." (F. I. Ill, 175). They usually nest in caves, in limestone 

 formations. (Watt). 



Caprimulgi. Night Jars. Almost universally insects cap- 

 tured on the wing. One species is said to live a good deal on fruit. 

 Jerd. B. I. I, 188. All live on insects which they capture on the 

 wing. Jerd. B. I. I, 192. Their food consists of insects and 

 largely of beetles which they capture chiefly, at all events, on the 

 wing. F. I. Ill, 184. The food consists, as a rule, of insects, and 

 especially beetles, captured in the air ; but the Podargidae are 

 asserted to pick Pbasmidse and Cicadid* off the trees, and even 

 to eat fruit, a? Steatornis does, and mice. E. B. C. N. H., 417. 



1091. Caprimulgus asiaticus. Common Indian Night-jar. 

 Enters verandahs in search of moths. Jerd. B. I. I, 177. Va- 

 rious moths and insects. Bomb. Gaz. Cutch, Vol. X., pape 63, 

 & Vol. XII, 34. 



1093. Caprimulgus mawurus. Horsfield's Night-jar.
