Tanda lapangan kunci

• Plumage Color. Look for the overall bright, almost uniform yellow coloration, especially on the underparts. This is a key differentiator from other white-eyes.
• Eye-ring. Observe the prominent, broad, and complete white eye-ring. This feature is characteristic of all white-eyes but its distinctness on a bright yellow head is notable for Z. flavus.
• Habitat. Consider the habitat. If you are in coastal or lowland areas of Java, especially in mangroves or scrub, and see a bright yellow white-eye, it is very likely Z. flavus.
• Behavior. Watch for its active, acrobatic foraging style, often in small, chattering flocks, moving quickly through foliage.
• Vocalization. Listen for its high-pitched, warbling song and soft 'tsee-tsee' contact calls.
