Black-bellied wren

The black-bellied wren (Pheugopedius fasciatoventris) is a species of bird in the family Troglodytidae. It is found in Colombia, Costa Rica, and Panama.

Male black-bellied wrens weigh 23.5 to 34.5 g (0.83 to 1.22 oz) and females 19.5 to 28.5 g (0.69 to 1.01 oz). Adults of all three subspecies have a rich chestnut back and tail; the latter has black bars. They have a white supercilium of varying size above a grayish face and are white on the chin, throat, and breast. All three have a black belly, but that of P. f. melanogaster is unmarked while those of the other two subspecies have thin white bars.
