The black-banded woodcreeper (Dendrocolaptes picumnus) is a sub-oscine passerine bird in subfamily Dendrocolaptinae of the ovenbird family Furnariidae.

[2] It is found discontinuously from Chiapas, Mexico, to Panama and in every mainland South American country except Chile and Uruguay.

Early 21st century publications posit that the black-banded woodcreeper should be split into at least two species that are paraphyletic with respect to D. hoffmannsi and D.

Adults of the nominate subspecies D. p. picumnus have a dusky face and neck with buffy to tawny streaks and a faint supercilium and eyering.

Their back, scapulars and wing coverts are olive-brown; their back has fine pale streaks and faint dark bars and the coverts have pale streaks and dark bands near their ends.

The population in Mexico and northern Central America favors pine and pine-oak woodlands.

[8][9][10][11][12][13] The black-banded woodcreeper is a year-round resident in most of its range, though in the north it might move from higher to lower elevation after breeding.

[8][9][10][11][12][13] The black-banded woodcreeper's nesting season varies geographically, for instance in May and June in Venezuela, March to May in Guyana, and including September in northeastern Brazil.

The species remains paired through the year and both parents incubate the clutch and care for nestlings.

The species has a wide variety of calls: "short whinny, nasal 'wrenh' with upward inflection, simple 'oi' falling in pitch, squealing 'squeeh' during fights, snarling 'chauhhh-eesk' in alarm, grunting series of 'uk-uk-uk' at competitors, [and] various rattles.

It has an extremely large range and an estimated population of between 50,000 and 500,000 mature individuals; the latter, however, is believed to be decreasing.

"At least some populations believed to require nearly continuous forest, and thus highly sensitive to human disturbance.
