There is extremely little Jocal variation in this species 
throughout its range and a series from Borneo differs in no 
way from a large number from the Malay Peninsula. Indtvtd- 
val variation is considerable, the rufous buff of the belly and 
flanks varying greatly in intensity. It is only very old birds 
indeed that entirely lose the black, crescentic edgings to the 
feathers of the sides of the breast indicative of immaturity. 
A common rice-field bird wherever it occurs, though also 
found on the higher reaches of the rivers in deep jungle. 
Occasionally also on small islands in the Straits of Malacca 
during the winter months, evidently on migration.

There is little to add to what has already been written on 
the variability of the Indo-Malayan races of blue-and-white 
Kingfisher. The three specimens listed above differ consider- 
ably, one having the ear-coverts almost black, a greenish black 
band round the nape continuous with them, while in the other 
the ear-coverts are much more bluish green and the nuchal 
collar is very narrow and barely visible. The flanks are pure 
white with no trace of the buffy tint present in the bright blue 
birds characterised as H. humii, Sharpe. The mantle in all 
is greenish blue but the wings and wing coverts are pure blue.
