The Philippine mallard does not often occur in large numbers; usually, 
however, it may be found in pairs in tide creeks, small ponds, or other 
suitable localities. 
“We found this fine mallard to be rare in all the localities visited by 
us with the single exception of the region about the town of Milagros, 
on the west coast of the Island of Masbate. In the last-mentioned district 
it was very abundant, occurring in great flocks.” (Bourns and Wor- 
cester MS.) 
“Extraordinarily abundant on the Abulug River in northern Luzon in 
March, 1906. Flocks of twenty-five to two hundred were constantly met 
with on the lower river.” (Worcester.) 
Genus POLIONETTA Oates, 1899. 
A wide yellow band across the tip of bill, otherwise like Anas from
