Spot-breasted Wren

The Spot-breasted Wren, a small bird with a length ranging from 12.5 to 14 cm, is a delightful sight with its reddish-brown crown and upperparts, and a more chestnut rump. The tail is a muted brown adorned with narrow dark bars. A striking white supercilium contrasts with the face and neck, which are intricately streaked with black and white. The throat, chest, and belly center are a pale gray, speckled with black spots, while the flanks and lower belly boast an orange-buff hue, sans spots. Juveniles present a paler version of adults, with less pronounced facial markings and spots.
