Black-throated Wren

The black-throated wren, a small bird of the Troglodytidae family, measures a modest 15 cm in length. The males, slightly heavier, range from 24.3 to 27.3 grams, while the females tip the scales at approximately 22.5 grams. This species boasts a dark reddish-brown plumage on its crown and upperparts, with a notably redder hue on the rump. Its tail is a blackish brown adorned with subtle buffy markings. The face is predominantly black with white accents, and the chin, throat, and upper chest share this dark coloration. A reddish-brown band graces the mid-chest, transitioning to a reddish chestnut on the lower chest and belly. Juveniles present a more uniform dull dark brown, with less distinction between their upper and underparts compared to adults.

Identification Tips

When identifying the black-throated wren, look for the striking black throat and face with white markings, as well as the reddish-brown tones on the mid-chest and belly. The contrast between the dark upperparts and the lighter underparts is less pronounced in juveniles.

Habitat

This wren favors the lowland and foothill forests, showing a particular affinity for secondary growth. It is often found in proximity to water sources, which provide a lush environment for its foraging activities.

Distribution

Originally thought to inhabit areas from southeastern Nicaragua through eastern Costa Rica to western Panama, the black-throated wren's range has expanded to include sightings in northern Nicaragua and eastern Honduras since 2010.

Behaviour

Feeding The black-throated wren is known to forage close to the ground within dense vegetation. Its diet primarily consists of insects and spiders, although a comprehensive analysis of its feeding habits is yet to be documented.

Conservation Status

The IUCN has classified the black-throated wren as Least Concern. Despite this, there is a suspicion that the population may be declining due to ongoing habitat destruction and fragmentation.
