The Common Gliding Lizard
Draco sumatranus is generally encountered in disturbed or man-made
habitats such as parks and gardens or wayside trees, where abundant sunlight
is the norm. It is rarely found in the shade of primary or mature secondary
forests, preferring to keep to the forest edge.
Its dorsal surface is symmetrically mottled with light brown and dark brown,
and the patagium is black with brown mottling.
The triangular gular flag of the male is mainly bright yellow, but at the
base is pale yellow to white and mottled with dark flecks. The
forehead and crown of the male is often turquoise to bluish. The female
possesses a small, mottled blue gular flag.
The species has been observed to feed mainly on small ants.
It was once considered a subspecies of Draco volans (i.e. D.
volans sumatranus) but was recently elevated to species status.
The Common Gliding Lizard ranges from southern Thailand, Peninsular Malaysia
and Singapore to Sumatra and Borneo (including the adjacent Philippine
island of Palawan).
