The spot-breasted wren is 12.5 to 14 cm (4.9 to 5.5 in) long; males weigh 14.3 to 16.8 g (0.50 to 0.59 oz) and females 12.4 to 16.2 g (0.44 to 0.57 oz). Adults of the nominate subspecies have a reddish brown crown and upperparts; the rump is more chestnut. Their tail is dull brown with narrow dark bars. They have a white supercilium and the rest of the face and neck are streaked with black and white. The throat, chest, and the center of the belly are pale gray with black spots and the flanks and lower belly are orange-buff with no spots. Juveniles are paler than the adult and the facial markings and spots are less extensive and dimmer.<p>P. m. microstictus is not as reddish as the nominate and the spots on its breast are smaller and fewer. P. m. canobrunneus is paler than the nominate and its crown is light buffy cinnamon. P. m. umbrinus (including petersi and varians) is larger and darker than the nominate.

Taxonomía

The spot-breasted wren has at times been treated as conspecific with rufous-breasted wren (P. rutilus) and speckle-breasted wren (P. sclateri). They do form a superspecies.<p>The International Ornithological Committee (IOC) recognizes five subspecies:<p>The Clements taxonomy recognizes a sixth subspecies:<p>BirdLife International (BLI) does not recognize either petersi or varians, considering them "indistinguishable from umbrinus".

Comportamiento

The spot-breasted wren forages at low levels in dense vegetation, usually in pairs or family groups. Its diet is not well defined but is probably mostly invertebrates.<p>Some details of the spot-breasted wren's breeding phenology are known. Its breeding season varies by latitude. Its nest is dome-shaped, has a side entrance, and is typically placed in the crotch of a tree or in ferns up to 6 m (20 ft) above the ground. The clutch size is three to four. Both sexes feed the young.<p>The spot-breasted wren's song is " a cheerful series of clear whistling gurgles" given by both sexes [1].
