Some Sumatran birds have the forehead slightly tinged 
with orange but this also occurs in one of a large series from 
Java and is not sufficient to found a racial distinction upon.

“Male, iris, inner ring pale blue, outer orange, bill pale 
grey at tip, cere, etc. silvery cobalt, orbital skin pale apple 
green, feet lake, claws horn.’ 
“Female, iris inner ring pale blue, outer mauve, bill tip, 
whitish horn, base of cete silvery cobalt, orbital skin Nile green, 
feet deep coral red, claws horn.” 
This handsome pin-tailed green pigeon occurred sporadi- 
cally throughout the lower slopes of the Korinchi valley both in 
secondary jungle and in old forest up to a limit of about 5,000 
feet, above which level it was replaced by S. korthalsi; at 
Sungei Kumbang it was extremely common, feeding in very 
large flocks on lofty fig trees from which it was difficult to 
bring birds down. Except on these trees in the late afternoon 
it was not much in evidence. It had two notes, a low, rather 
musical coo and a harsh, disagreeable chuckle, which was 
continuously heard while the birds were feeding. 
A single specimen was obtained at Pasir Ganting at sea 
level, so that, like its congeners in the Malay Peninsula, this 
species performs migrations to the coast though it does not 
probably reside permanently at low elevations. 
The whole series of males are very uniform, differences 
dependent on age being mainly in the orange pectoral collar 
and in the grey on the hind neck, which are less developed in 
younger birds, which also have the under tail coverts paler 
cinnamon and more mixed with olive green. 
The general green tint of the females appears somewhat 
darker than in the other sex.
