This heavy Wood-Duck is common in Peninsular Siam, where 



it feeds in the rice fields largely on species of snail ( Ampullar ia), 



and lies up for the night in the adjacent jungle. Our men met with 



it on a small stream near Hat Sanuk, but did not secure specimens.

Said to be common at the north end of the Tale Sap and in 



the Tale Noi in Patelung, but rare everywhere else in the Peninsula.
