   The strong sexual dimorphism is a key feature. Males are unmistakable with their black and red-orange pattern. Females are distinguished by their grey and yellow coloration, particularly the yellow rump and wing patch. Their active foraging style and habit of joining mixed-species flocks are also characteristic.

Tanda lapangan kunci

• Plumage Coloration (Male). Look for the striking contrast of glossy black on the head, mantle, and upper breast, sharply demarcated from the bright red-orange lower breast, belly, rump, and outer tail feathers. A prominent red-orange wing patch on black wings is also key.
• Plumage Coloration (Female). Identify females by their grey head, mantle, and upper breast, contrasting with bright yellow lower breast, belly, rump, and outer tail feathers. A distinct yellow wing patch on dark grey wings is diagnostic.
• Habitat and Elevation. Focus your search in montane forests, typically above 900 meters. If you are at lower elevations, it is more likely to be a similar species like the Sunda Minivet.
• Behavior. Observe their active foraging style, gleaning insects from foliage and making short aerial sallies. They often move in small groups or as part of mixed-species flocks in the forest canopy.
• Vocalizations. Listen for their high-pitched, clear, and often rapid 'swee-swee-swee' or 'twee-twee-twee' song, which can accelerate into a trill. Their sharp 'chip' calls are also distinctive.
