The Siamese White-crested Laughing-Thrush was commonly distributed över the 

 whole of Siarn. In the forests on the boundary between Siarn and Tenasserim it was, 

 however, rather rare and only a few specimens were observed. In the Northern and 

 Central Provinces it is very abundant and one of the birds most often met with by the 

 traveller.
