About Pheugopedius fasciatoventris (Lafresnaye, 1845)
This species is Pheugopedius fasciatoventris (Lafresnaye, 1845), commonly called the black-bellied wren. Male black-bellied wrens weigh between 23.5 and 34.5 g (0.83 to 1.22 oz), while females weigh between 19.5 and 28.5 g (0.69 to 1.01 oz). Adult individuals of all three recognized subspecies share a rich chestnut-colored back and tail; the tail features black bars. All adults have a white supercilium (eyebrow stripe) of variable size above a grayish face, and white coloration on the chin, throat, and breast. All three subspecies have a black belly: the belly of P. f. melanogaster is unmarked, while the two other subspecies have thin white bars on their black bellies.
Three subspecies are distributed across different geographic ranges. P. f. melanogaster, the northernmost subspecies, occurs from the Gulf of Nicoya in western Costa Rica, through western Panama, to the Canal Zone. P. f. albigularis ranges from the Canal Zone into Chocó Department, Colombia. The nominate subspecies P. f. fasciatoventris is found in northwestern and central Colombia, extending east to the foothills of the Sierra Nevada de Santa Marta and south into the Cauca and Magdalena valleys. As a species, it inhabits the interior and edges of both primary and secondary forest, and is often associated with streams.
