Tapajos Hermit (Phaethornis aethopygus): uplist from Near Threatened to Vulnerable?

This discussion was first published as part of the 2016 Red List update. At the time a decision regarding its status was pended, but to enable potential reassessment of this species as part of the 2018 Red List update this post remains open and the date of posting has been updated.

BirdLife species factsheet for Tapajos Hermit

Tapajos Hermit is endemic to Brazil. It is known only from the vicinity of the Teles Pires, Tapajós and Xingu rivers, south of the Amazon (Piacentini et al. 2009). The species is listed as Near Threatened, approaching the criteria for A2c+3c+4c. Ongoing deforestation in its range is suspected to be driving at least a moderately rapid population decline. The species’s population size has not been directly estimated.

In the Brazilian Red List assessment for birds (MMA 2014) this species is listed as Vulnerable under criterion A3ce+4ce. The species is forest-dependent and is rare in secondary forests. High rates of deforestation have taken place within the species’s range and the range is within the zone of influence of highway BR-163, the paving of which is expected to bring even greater habitat destruction. Habitat loss within the species’s range is predicted to be c.25% however population modelling of species within the same area estimates losses of 32%. The species’s assessment on the Brazilian Red List can be accessed here.

Up-to-date information is requested on the species’s population size reduction, rates of habitat loss and additional threats. Confirmation that the species is likely to undergo a decline of >30% in 13 years (three generations) would likely qualify the species for Vulnerable under criterion A3c+4c. Comments on the proposed uplisting are welcome.

  1. Alexander Lees says:

    Sp is vulnerable to habitat modification, common only in undisturbed primary forest, scarce in degraded primary and largely absent from secondary forests where P. ruber is common.

  2. James Westrip (BirdLife) says:

    Based on available information, our proposal for the 2016 Red List would be to pend the decision on this species and keep this discussion open until 2017, while leaving the current Red List category unchanged in the 2016 update.

    Final 2016 Red List categories will be published on the BirdLife and IUCN websites in early December, following further checking of information relevant to the assessments by both BirdLife and IUCN.
