Tanda lapangan kunci

• Size and Shape. Look for a relatively small, compact shrikethrush (16-18 cm) with a stout body and a strong, slightly hooked bill.
• Plumage Coloration. Observe the overall dull olive-brown to grey-brown upperparts and paler, greyish-white to dull buff underparts. Note the absence of strong patterns or bright colors.
• Bill. The dark grey to blackish, stout bill is a consistent feature and helps distinguish it from some other forest passerines.
• Vocalizations. Listen for its distinctive, melodious, whistled song, which is often the first indication of its presence. The song is rich and varied, often with rising or falling inflections.
• Behavior. Watch for its quiet, deliberate movements through dense undergrowth or mid-story, often gleaning insects from foliage.
