Burong olok-olok (jester-bird) is the Brown Gannet.
[edit]By A. W. Hamilton
Burong olok-olok is mentioned in Wilkinson's Dictionary as an unidentified bird; but in reality the bird is not such a jest as its Malayan name would seem to imply, and it has been identified for me kindly by Mr. H. C. Robinson, as the Brown Gannet or Sulasula (Linn.).
The brown gannet or olok-olok as it is called in Kedah is a dark plumaged sea bird with webbed feet, solitary specimens of which are usually met with at sea off the coast of Kedah in company with a flock of gulls.
