Demography and Populations

Measures of Breeding Activity

There is no information on either the number of broods per year or rates of breeding success.

Life Span and Survivorship

No information, although one bird was recaptured just over 26 months after it had been banded at a site in se. Brazil (Lopes et al. 1980).

Mortality and Disease

There are no data on mortality, but this species is susceptible to avian malaria (Ribeiro et al. 2005) and is parasitized by the tick Amblyomma longirostre (Arzua et al. 2005, Labruna et al. 2009).

Population Status

The Olivaceous Woodcreeper is not globally threatened. Because of its small size, this species is inconspicuous and may be difficult to detect visually. Even so, it is fairly common to common from northern Mexico, locally, through Central America and over most of Amazonia and the rest of South America. By contrast, this species is uncommon in Guyana (Braun et al. 2007)—excepting in the westernmost part of the country (O’Shea et al. 2007)—French Guinana (Thiollay 1990), and parts of south-central Amazonia, evidently is absent from much of e. Amazonia, and is unrecorded in Suriname (Marantz et al. 2003).

Population Regulation

Population densities in western Amazonia vary between ca 6.5 birds/100 ha (Robinson and Terborgh 1997) and ca 19 birds/100 ha (Munn 1985, Pierpont 1986), but densities are much lower on the Guianan Shield, nearer ca1.8 birds/100 ha (Thiollay 1994).
