Stripe-throated wren
The stripe-throated wren ("Cantorchilus leucopogon") is a species of bird in the family Troglodytidae. It is found in Colombia, Ecuador, and Panama. Taxonomy and systematics. The stripe-throated wren has at times been treated as conspecific with the stripe-breasted wren ("Cantorchilus thoracicus") and the two form a superspecies. The species has two subspecies, the nominate "C. l. leucopogon" and "C. l. grisescens". Description. The stripe-throated wren is 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. Distribution and habitat. The stripe-throated wren of subspecies "C. l. grisescens" is the more easterly of the two. It is found on the Caribbean slope of eastern Panama  into northern Colombia. The nominate "C. l. leucopogon" is found on the Pacific slope, from eastern Panama south through western Colombia into western Ecuador. It inhabits the edges of "várzea" and secondary forests from sea level up to . Behavior. Feeding. The stripe-throated wren forages in pairs, often as part of a mixed-species foraging flock. It typically hunts in thick vegetation between above the ground. Its diet has not been extensively documented but is known to include insects. Breeding. 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." Vocalization. The stripe-throated wren's song is "a tuneless repetition of 2–3 notes, 'chi-chi-chi'". Status. The IUCN has assessed the stripe-throated wren as being of Least Concern. However, it is "apparently rather scarce throughout much of its range."
