Their face is mostly dark brown with black and white tips on some feathers. Their upperparts are mostly dark olive brown to greenish brown, sometimes with faint black bars. Their flight feathers are dark brown with pale edges and tips on the secondaries and tertials. Their tail is dark brown; the innermost pair of feathers have mostly white inner webs and the outer two pairs have a narrow white band near the end. Their chin and throat are black-brown with fine white markings. Their underparts are variable but usually brown or greenish brown with black and white feather tips that show in rows.

分类信息
The varzea piculet was first described in 1912 by the German-Brazilian ornithologist Emilie Snethlage who collected birds in Brazil for two decades.<p>At least one author has suggested that the varzea piculet might be a subspecies of the spotted piculet (P. pygmaeus). It occasionally hybridizes with the white-barred piculet (P. cirratus).<p>The specific epithet refers to "várzea", the Brazilian name for the seasonally flooded forest close to the Amazon River.<p>The varzea piculet is monotypic.

As far as is known the varzea piculet is a year-round resident throughout its range.<p>Nothing is known about the varzea piculet's foraging technique or diet.<p>The varzea piculet's breeding season is poorly known but may be from June to December; young birds have been recorded in September. Nothing else is known about its breeding biology.<p>As of early 2023 xeno-canto had only five recordings of the varzea piculet's song. The Cornell Lab of Ornithology's Macaulay Library had seven with some overlap with xeno-canto. The song has not been transcribed.
