Straight-billed Woodcreeper (Dendroplex picus)

First nest records, nestling growth and morphometrics of Dendroplex picus peruvianus (Aves: Dendrocolaptidae) in southwestern Brazilian Amazon

“…Overall mean body mass for the species is consistent with other studies (Oniki 1978, Silva et al 1990, Marantz et al 2020. Wing, bill, tail, and tarsus were all similar to those reported in southwestern Peruvian, Brazilian and Bolivian Amazonia (Hellmayr 1910, Zimmer 1934, Pinto & Camargo 1954.…”

“…The Straight-billed Woodcreeper Dendroplex picus ranges from Panama to northern South America (Marantz et al 2020). Thirteen subspecies of D. picus are recognized (Marantz et al 2020).…”

“…The Straight-billed Woodcreeper Dendroplex picus ranges from Panama to northern South America (Marantz et al 2020). Thirteen subspecies of D. picus are recognized (Marantz et al 2020). The eastern extreme of the Brazilian state of Acre and adjacent areas of the lowlands of southeastern Peru and northeastern Bolivia represent the limit of the distribution of D. p. peruvianus in southwestern Amazon (Schulenberg et al 2010, Guilherme 2016, Marantz et al 2020.…”

The Straight-billed Woodcreeper is typically found, in the state of Acre, in upland forests, along edges and in open areas, including anthropic clearings with palms, and urban areas.…”

Azara's no. 243 ‘Trepador de pico corto’ is a Lesser Woodcreeper Xiphorhynchus fuscus

“…These differences seem to me sufficient to consider it a distinct species, you see in this family, like all of those with many characters in common, any difference is of greater importance than many similarities; and the difference in the length of the bill is very great.' Ever since Lichtenstein (1818) tentatively associated the 'Trepador pico corto' with Straight-billed Woodcreeper Dendroplex picus (J. F. Gmelin, 1788), a species distributed well north of Paraguay, from Panama south to Amazonian Bolivia and the northern Pantanal of Brazil (Marantz et al 2019a), there has been little effort to improve on that identification. In fact, it was repeated by Hartlaub (1847), Sclater (1890), Laubmann (1939) and Pereyra (1945) 'I do not know whether the slight differences which Monsieur d'Azara has remarked upon between this bird and the preceding, suffice to constitute two distinct species; and my doubt is all the more founded on the fact that of the only two Trepador pico cortos observed by this traveller, one had a total length of an inch less than the other, from which it can be concluded that the dimensions of these birds are subject to variation.…”
