Abstract

LIMA, Jônatas  and  GUILHERME, Edson. First nest records, nestling growth and morphometrics of Dendroplex picus peruvianus (Aves: Dendrocolaptidae) in southwestern Brazilian Amazon. Rev. peru biol. [online]. 2021, vol.28, n.3, e20476. ISSN 1727-9933.  http://dx.doi.org/10.15381/rpb.v28i3.20476.

We reported the first data on the breeding and growth in Dendroplex picus peru-vianus from a forest fragment in southwestern Amazonia. We observed and netted this species between 1999 and 2019. We found two active nests in 2012 and 2013, but we monitored only one. Clutch size was two eggs, incubated for 16 days. Theconstant growth rate (K) of nestlings was 0.31 with a growth asymptote of 46.3 g. We recorded a longest minimum longevity of eight years. Our records showed that D. p. peruvianus breeds mainly in the rainy season (September-March) overlapping with the molt period.

Keywords : Dendroplex picus peruvianus; Dendrocolaptidae; Neotropical birds; reproduction; breeding; seasonality.
