Flying Lizard Display — Danum Valley Borneo
The flying lizard (Draco volans and related species) of Borneo's lowland forest extends its ribbed gliding membrane — supported by elongated ribs covered in vivid orange, yellow, and blue skin — to glide up to 8 metres between tree trunks in courtship and territorial displays that are entirely visible from the forest paths of the Danum Valley. The male's throat flag (dewlap) is extended simultaneously with the wing display — a combination of orange wing panels, yellow dewlap, and iridescent blue spots that creates one of the forest floor's most vivid and rapid visual signals. The Danum Valley Conservation Area's canopy walkway and forest paths provide frequent flying lizard encounters, and the contrast between the lizard's unremarkable tree-trunk camouflage at rest and the sudden explosion of colour during display creates a wildlife moment of memorable surprise. Each male defends a cluster of 2–3 females on adjacent trees.
About this spectacle
Along the shaded forest paths of the Danum Valley Conservation Area in Sabah, Borneo, the flying lizard offers one of the lowland jungle's most startling moments. A male Draco, perfectly camouflaged against bark, suddenly launches from a tree trunk and unfurls a pair of vivid gliding membranes — orange-panelled wings edged with yellow and speckled with iridescent blue — as he glides up to 8 metres to a rival's territory or a female's perch. The simultaneous extension of his bright yellow dewlap completes the display, the whole performance lasting only seconds before the wings snap shut and the lizard vanishes again into bark-coloured stillness. Males defend clusters of two to three females across adjacent trees, so patient visitors on any given trail section may witness multiple aerial sorties and confrontations within minutes. The canopy walkway and ground-level paths both offer good sightlines at eye-level to lower trunks. Morning light filtering through the canopy catches the membranes mid-glide, briefly illuminating them like stained glass. The contrast between invisibility and sudden chromatic explosion is what makes the encounter so viscerally memorable.
