93. Fregat a a q uil a (Linn.). Native name: Bientajong. 



Billiton. On the neighbouring Island of Lankwa.s 

 and probably on other small islands , this bird 

 is passing the night in great number. The fact, 

 that never a nest of these birds was found , caused 

 the belief amongst the natives, that this bird flies 

 so extremely high up in the air to drop his egg, 

 that this latter breeds out while dropping, and 

 that, in stead of the egg, the young bird reaches 

 the sea.
