Archived 2019 topic: The newly described taxon Painted Manakin (Machaeropterus eckelberryi) is to be recognized as a species by BirdLife International.

Painted Manakin (Machaeropterus eckelberryi) was discovered in 1996 in the 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 2017 (Lane et al. 2017).

Based on current information, Painted Manakin seems to be restricted to a small area in the foothills of the Andes in the departments of San Martín and Loreto in northern Peru, including the Cordillera Azul National Park (Lane et al. 2017). It is assumed that its range spans the ridges of the eastern flanks of the Cordillera Azul, Cordillera Escalera and the Mayo Valley at altitudes between c. 550 and 1,600 m (Lane et al. 2017). The population size has not been estimated.

Painted Manakin inhabits woodlands of up to 20 m canopy height on poor, sandy soils (Lane et al. 2017). It is frequently found near Melastomaceae trees, where it feeds on berries in the mid-story and canopy layer (Lane et al. 2017).

To date, there are no known threats to the species. Its preferred poor-soil woodland habitat is not suitable for agriculture and therefore not subject to the heavy logging that is currently ongoing, particularly in the Cordillera Azul (Lane et al. 2017, Moncrieff et al. 2018). Moreover, large parts of the range are protected in the Cordillera Azul National Park. Overall, Painted Manakin seems to be under much lower threat than other endemic species of the north-central Peruvian Andes, including the recently discovered Cordillera Azul Antbird (Myrmoderus eowilsoni) (Lane et al. 2017, Moncrieff et al. 2018).

Here, we present our assessment against all criteria for Painted Manakin.

Criterion A – It has been suggested that the population of Painted Manakin is currently not under any threat. Therefore, unless other information becomes available, it is tentatively assumed that the species is stable, and it may be listed as Least Concern under Criterion A.

Criterion B – The Extent of Occurrence (EOO) has been calculated at c. 36,000 km2. This is too large to warrant listing as threatened under Criterion B1 (EOO < 20,000 km2). The maximum Area of Occupancy (AOO), as calculated from a 2 km by 2 km grid overlaid over the mapped range, is c. 25,000 km2. This is does not approach the threshold for listing as threatened under Criterion B2 (AOO < 2,000 km2). Overall, the species may be considered Least Concern under Criterion B.

Criterion C – The population size has not been quantified. However, we can infer a preliminary population estimate from the recently discovered Cordillera Azul Antbird, which occurs in mature forests in the Cordillera Azul. The population size of the Cordillera Azul Antbird has been estimated at 7,000-34,000 mature individuals. However, this species is thought to be in decline due to habitat loss, while the estimate is only preliminary as the range might be larger than currently known (Moncrieff et al. 2018). As Painted Manakin is thought to be stable and under no serious threat, the population size is likely larger. Unless new information becomes available, we can assume that the population of Painted Manakin is larger than 10,000 mature individuals. Given that it is not considered to be in decline, it does not warrant listing as threatened under Criterion C, and thus may be considered Least Concern under this criterion.

Criterion D – The population size and range are too large to warrant listing as threatened, and thus the species is assessed as Least Concern under Criterion D.

Criterion E – To the best of our knowledge no quantitative analysis of extinction risk has been conducted for this species. Therefore, it cannot be assessed against this criterion.

Therefore, it is proposed that Painted Manakin (Machaeropterus eckelberryi) be listed as Least Concern. We welcome any comments on this proposed listing and specifically request information on the population size of the species.

Please note that this topic is not designed to be a general discussion about the ecology of the species, rather a discussion of its Red List status. Therefore, please make sure your comments are relevant to the discussion outlined in the topic.

  1. Red List Team (BirdLife International) says:

    Preliminary proposal
    Based on available information, our preliminary proposal for the 2019 Red List would be to adopt the proposed classifications outlined in the initial forum discussion.
    There is now a period for further comments until the final deadline in mid-July, after which the recommended categorisations will be put forward to IUCN.
    Please note that we will then only post final recommended categorisations on forum discussions where these differ from those in the initial proposal.
    The final 2019 Red List categories will be published on the BirdLife and IUCN websites in December, following further checking of information relevant to the assessments by both BirdLife and IUCN.
