Tanda lapangan kunci

• Male Plumage. Look for the brilliant crimson breast and iridescent purplish-blue head and throat. The narrow, iridescent blue-green malar stripe is also a key field mark.
• Female Plumage. Identify by the olive-green upperparts and dull yellowish-green underparts. Note the lack of any strong yellow on the belly, which distinguishes it from some other female sunbirds.
• Bill Shape. Observe the long, slender, and distinctly decurved black bill, characteristic of nectar-feeding sunbirds.
• Behavior. Watch for active feeding at flowers, often hovering or perching briefly. Their rapid, darting flight is also distinctive.
• Vocalizations. Listen for the high-pitched, rapid 'chip-chip-chip' song or sharp 'tsip' calls.
