   Pronounced sexual dimorphism in cap color: males have a glossy black cap extending from the forehead to the nape, while females have a chestnut or reddish-brown cap. Both sexes have similar body plumage.

Segni di campo chiave

• Cap Color. The most reliable field mark: glossy black cap for males, reddish-brown/chestnut cap for females and juveniles. This is visible even at a distance.
• Plumage. Overall plain greyish-brown upperparts and paler greyish-white underparts. Look for the lack of streaking or strong patterns on the body.
• Song. Listen for the distinctive, rich, fluty, and melodious warbling song, often starting hesitantly and then becoming clearer and more powerful. It's a key identification feature, especially when the bird is hidden in foliage.
• Behavior. Watch for its active foraging style, flitting through dense vegetation, gleaning insects. It can be quite shy but will often sing from exposed perches.
