The upperparts are olive-brown, becoming slightly paler on the rump and uppertail coverts. The wings and tail are dark brown with olive-brown edgings. Underparts are dull whitish to pale greyish-brown, often with a faint yellowish wash on the flanks and vent. Some subspecies may show a more pronounced grey wash on the breast.

Key field marks

• Rufous Cap. Look for the bright reddish-brown crown and nape, which is the most distinctive field mark.
• Greyish Face. Note the contrasting greyish face and supercilium against the rufous cap and olive-brown upperparts.
• Olive-brown Upperparts. Observe the overall olive-brown coloration of the back, wings, and tail.
• Pale Underparts. Check for dull whitish to pale greyish-brown underparts, sometimes with a yellowish wash.
• Small Size and Active Behavior. Its small size (around 11 cm) and constant movement in dense undergrowth are characteristic. Listen for its soft contact calls within a flock.
• Vocalizations. Learn its clear, sweet, repetitive whistling song and soft 'chip' contact calls, which are often the first indication of its presence.
