Résumé :	On 28 October 1996, 1 found a Mottled Piculet (Picumnus nebulosus) nest on Anhangava Mountain in southern Brazil. The nest cavity (10.6 cm X 5.6 cm) was in the trunk of a dead tree at a height of 85 cm. The circumference of the trunk at cavity height was 37 cm and the cavity entrance (diameter = 2.46 cm) was located near the top of the chamber. The nest was lined with wood fragments and contained four eggs. On average, eggs were 16.3-mm long and 13.0-mm wide and weighed 1.38 g. The parents spent 17 d incubating the eggs. Hatchlings had closed eyes and no feathers. By 20 d posthatching, nestlings were active and had plumage similar to that of adult females. Young fledging 22-25 d alter hatching Nestling weight gain and tarsus growth were fastest at the beginning of the nestling period, while wing, tail, and culmen growth had a linear relationship with nestling age. Both the adult male and female provided parental care during the nestling period. Although, the nesting behavior of Mottled Piculets was similar to that reported for other members of the genus, information on the reproductive biology of species in the genus Picumnus is still limited.
