Tanda lapangan kunci

• Size and Shape. Look for a very small, compact kingfisher with a relatively short tail and a pointed bill.
• Plumage Coloration. Observe the striking contrast: bright orange underparts, cheeks, and collar, against a dark (blue-black) back and crown. The bright red bill and legs are also prominent.
• Rump Patch. If seen in flight or from behind, look for the distinctive bright violet-blue rump patch, which is a key identifier for C. erithaca.
• Habitat and Behavior. Search in dense, shaded undergrowth near slow-moving water. Look for a bird perching low, often motionless, before making quick sallies for prey.
• Vocalizations. Listen for its high-pitched, thin 'tseet-tseet' or 'chip-chip' calls, which are often easier to detect than seeing the bird itself.
