Chochín de Garganta Estriada

Identificación

The stripe-throated wren is 12 cm (4.7 in) long. Adults of the nominate subspecies have a dark brown crown and upperparts; the latter are more rufescent on the rump. Their tail is reddish brown with narrow blackish bars. They have a grayish white supercilium. The rest of the face, chin, and throat have black and grayish white streaks that end abruptly at the deep reddish buff upper chest. That color continues and becomes darker and richer through the belly to the vent. Juveniles are similar to the adults but the facial and throat streaking is less well defined. C. l. grisescens is paler and grayer overall.

Comportamiento

The stripe-throated wren forages in pairs, often as part of a mixed-species foraging flock. It typically hunts in thick vegetation between 3 and 10 m (9.8 and 32.8 ft) above the ground. Its diet has not been extensively documented but is known to include insects.<p>Little is known about the stripe-throated wren's breeding phenology. Its nest is "an untidy ball with side entrance, usually placed near end of small branch with little effort at concealment."<p>The stripe-throated wren's song is "a tuneless repetition of 2–3 notes, 'chi-chi-chi'".
