Rufous-naped Greenlet Pachysylvia semibrunnea

  • Order: Passeriformes
  • Family: Vireonidae
  • Monotypic
  • Authors: David L. Slager


Conservation Status

The IUCN Red List status of Rufous-naped Greenlet is Least Concern (BirdLife International 2011). The population size and population trend are unknown but are not believed to approach the IUCN criteria for Vulnerable status (BirdLife International 2011). The range of Rufous-naped Greenlet includes some protected areas, e.g. Sierra de Perijá National Park, Venezuela (Brewer 2010).

Effects of human activity on populations

The Rufous-naped Greenlet has a medium sensitivity to human disturbance (Parker et al. 1996), and much of its geographic and elevational range falls within the coffee-growing regions of Colombia, Ecuador, and Venezuela. As such, the species may be susceptible to human land-use changes associated with agriculture. In Antioquia, Colombia, Rufous-naped Greenlets were fairly common at each of three shade coffee plantations surveyed (D. Slager personal observations).  However, they were found only in areas where a closed or semi-open canopy remained, such as shaded coffee or remnant patches of secondary forest in ravines (D. Slager personal observations). Rufous-naped Greenlets were not found in pasture, residential areas, or coffee plantations lacking a substantial canopy component (D. Slager personal observations).  On the west slope of the central Andes in Colombia, Rufous-naped Greenlets could still be found in 1.5-16.2 ha forest fragments 50-90 years after isolation (Renhifo 1999).
