This species is exceedingly numerous, forming large congregations in 

 sheltered situations on the Malayan Peninsula, and in the caves on the 

 numerous islands of limestone which stud the shores from Maulmein to 

 Java, and in such localities large deposits of Guano occur. The latter, 

 ("Ty Klawah" of the Malays, i. e. bats' manure,) has been tried by 

 agriculturists at Pinang, but has been found much less efficacious than 

 the Guano obtained from the swift (Collocalia) , producing the edible 

 nests.
