Varzea piculet Snethlage who collected birds in Brazil for two decades. The specific name refers to ""várzea"", the Brazilian name for the seasonally flooded forested area close to the Amazon River. There are no subspecies. This bird occasionally hybridises with the white-barred piculet "(Picumnus cirratus)". The varzea piculet is a small species, some in length. The male differs from the female in having variable amounts of red on the fore and mid-crown; this red patch is the result of the crown feathers having broad red tips, and the rest of the crown in males and the whole crown in females is black
Ocellated piculet slightly barred. The iris of the eye is black or brown, the beak is blackish and the legs and feet are grey. There is a grey orbital ring around the eye. Juveniles resemble females but are rather darker, with fine barring on the mantle and underparts. The ocellated piculet is native to South America. It is found in the foothills on the eastern side of the Andes, its range extending from Peru and Bolivia to northern Argentina, at altitudes between . Its habitat is primary rainforest and secondary moist forest, where it frequents bushy undergrowth, with vines, creepers and epiphytes.
