BirdLife species factsheet for Rufous-tailed Antbird Rufous-tailed Antbird Drymophila genei occurs in montane forests of south-east Brazil (south Espírito Santo, south-east Minas Gerais, Rio de Janeiro and north-east São Paulo) (Ridgely and Tudor 1994, Parker et al. 1996). It has been recorded at eight sites, most of which are isolated patches of habitat (J. M. Goerck in litt. 2000). It is currently listed as Near Threatened under criterion B1ab(i,ii,iii,iv,v) because it was thought to have a moderately small and highly fragmented range, likely to be in decline. However, mapping of this species’s range shows that its Extent of Occurrence (EOO) is larger than previously thought, estimated to be 43,300km2. Population declines could be occurring due to habitat degradation in parts of the range, as well as the effects of population isolation due to extreme fragmentation, but these declines are unlikely to be severe as the montane habitats occupied by this species are under limited pressure from human development. Also, the global population size has not been quantified, but this species is described as ‘common’ (Stotz et al. 1996). If this information is confirmed, and the species’s EOO does not approach 20,000km2 and the population is not in continuing decline, it would no longer approach the thresholds for Vulnerable under the range size criterion and would warrant downlisting to Least Concern. Further information on distribution, population size and trends is requested, and additional comments on the proposed downlisting are welcome. References: Parker, T. A., Stotz, D.

BirdLife thanks everyone who has provided information for the 2020 Red List update. The unprecedented volume of feedback has exceeded our processing capacity, especially given COVID-19. Consequently, it has not been possible to reassess every species that may require a category change in the 2020 update. However, all new information has been catalogued, and will be processed, reflected and acknowledged in relevant species’ assessments ASAP. Any further potential category changes will be prioritised, with work starting on the 2021 update in September 2020. Thanks for your understanding and support.

Resident populations of Rufous-tailed Antbird have remained steady in our area over the past 10 years. We find them to be locally common anywhere above 1600m in the Serra dos Orgaos National Park and the Tres Picos State Park, both in Rio de Janeiro State. In our local area there is little threat to this species by human development as most areas occupied by this species are now protected against further development. The only possible cause for concern is damage to their habitat by fires.
