   Males in breeding plumage are bright yellow on the underparts, with a black crown, mantle, and tail. The wings are black with two prominent white wing-bars. The back can be olive-green or black depending on the subspecies. Non-breeding males and females are generally duller, with olive-green upperparts, yellow underparts, and blackish wings with white wing-bars. Females typically lack the extensive black on the crown and back, having more olive-green. Juveniles resemble females but are even duller.

Tanda lapangan kunci

• Plumage Coloration. Look for the bright yellow underparts contrasting with black wings and two white wing-bars. In breeding males, note the glossy black cap and back. Females and non-breeding males are duller, with olive-green upperparts.
• Size and Shape. A small, compact passerine, about the size of a sparrow, with a relatively short tail and a slender, pointed bill.
• Vocalizations. Listen for its distinctive, often melodious whistling song ('wheee-tee' or 'wee-chu' followed by chattering notes) and sharp 'chip' calls. The song is a key identifier.
• Behavior. Observe its active foraging style, gleaning insects from foliage. During courtship, males perform a characteristic 'puffing up' display, making their plumage appear much larger.
• Habitat. Typically found in well-wooded areas, forest edges, gardens, and plantations, often in the mid-canopy or upper story of trees.
