Nest
Large, football-shaped, composed of dead leaves and rootlets in the lower branches of a tree over a steep slope.
Subspecies
Variation within accepted subspecies unclear and somewhat complex. In particular, birds from northern Indochina (possibly also southern China) with more white in collar are sometimes separated subspecifically as "assimilis", while subspecies divinus may be closer to latter or is possibly indistinguishable from some cyanicauda. Peninsular Malaysian birds, although included in psittacinus, are less distinctively patterned than Sumatran population and may be closer to nominate, or possibly represent an undescribed subspecies. Further taxonomic study is required.
The following 5 subspecies are recognised:
dalhousiae (Jameson, 1835) - Himalayan foothills eastern from northern India and Nepal, possibly south-eastern Bangladesh, and from northern Myanmar and southern China (western and southern Yunnan, south-western Guizhou, south-western Guangxi) south to northern Thailand, Laos and central Vietnam (central Annam). Also reported from south-eastern Tibet.
cyanicauda Riley, 1935 - South-eastern Thailand and Cambodia.
