The newly described taxon Cordillera Azul Antbird (Myrmoderus eowilsoni) is to be recognized as a species by BirdLife International
Posted on May 23, 2019 by Red List Team (BirdLife International)
Cordillera Azul Antbird (Myrmoderus eowilsoni) has been discovered in 2016 near Flor de Café in the western Cordillera Azul of the Peruvian Andes. Based on its vocalisation and on genetic and morphological analysis, the species was described as a new taxon in 2018 (Moncrieff et al. 2018).
Currently, Cordillera Azul Antbird is only known from the mountain ridge around the type locality between c. 1,300 and 1,700 m. However, it seems to be highly likely that the species has a wider distribution, encompassing further ridges in the Cordillera Azul and possibly also the Cordillera El Sira (Moncrieff et al. 2018). The authors assume that a large part of the population occurs in the Cordillera Azul National Park (Moncrieff et al. 2018).
The species inhabits tall, humid, montane forest with a dense vegetation cover in the understory. It seems to avoid secondary forest, edges and treefall gaps, but has been recorded in close proximity to large plantations (Moncrieff et al. 2018). Cordillera Azul Antbird keeps close to the ground and moves by walking or short, low flights (Moncrieff et al. 2018). The species is territorial; territories have been tentatively estimated at 0.25 km2 (Moncrieff et al. 2018).
Cordillera Azul Antbird was found to be fairly common in fragments of intact forest (Moncrieff et al. 2018). Based on the mean territory size of this species and the closely related Ferruginous-backed Antbird Mymoderus ferrugineus (Johnson et al. 2011), an estimate of habitat occupancy for Ferruginous-backed Antbird (Stouffer 2007) and the availability of suitable habitat, the authors produced a preliminary population estimate (Moncrieff et al. 2018): The Cordillera Azul National Park includes 1,940 km2 of forest between 1,300 and 1,700 m; hence the population of Cordillera Azul Antbird in the National Park may consist of 7,000-27,000 mature individuals. Including areas outside of the park in the right elevation throughout the entire cordillera increases the estimate to 9,000-34,000 mature individuals. Therefore, until more detailed information becomes available, we can place the population in the band 7,000-34,000 mature individuals.
The major threat to the forests around the type locality is the extensive, large-scale clear-cutting for conversion into coffee plantations. Until now however, the Cordillera Azul National Park protects large tracts of intact forest (Moncrieff et al. 2018).
