Common Flameback (Dinopium javanense) is being split: list D. everetti as Near Threatened?

This is part of a consultation on the Red List implications of extensive changes to BirdLife’s taxonomy for non-passerines

Lynx Edicions and BirdLife International will soon publish the HBW-BirdLife Illustrated Checklist of the Birds of the World, building off the Handbook of the Birds of the World series, and BirdLife’s annually updated taxonomic checklist.

The new Checklist will be based on the application of criteria for recognising species limits described by Tobias et al. (2010). Full details of the specific scores and the basis of these for each new taxonomic revision will be provided in the Checklist.

Following publication, an open and transparent mechanism will be established to allow people to comment on the taxonomic revisions or suggest new ones, and provide new information of relevance in order to inform regular updates. We are also actively seeking input via a discussion topic here regarding some potential taxonomic revisions that currently lack sufficient information.

The new Checklist will form the taxonomic basis of BirdLife’s assessments of the status of the world’s birds for the IUCN Red List. The taxonomic changes that will appear in volume 1 of the checklist (for non-passerines) will begin to be incorporated into the 2014 Red List update, with the remainder, and those for passerines (which will appear in volume 2 of the checklist), to be incorporated into subsequent Red List updates.

Preliminary Red List assessments have been carried out for the newly split or lumped taxa. We are now requesting comments and feedback on these preliminary assessments.

Common Flameback Dinopium javanense is being split into D. javanense and D. everetti, following the application of criteria set out by Tobias et al. (2010).

Prior to this taxonomic change, D. javanense (BirdLife species factsheet) was listed as Least Concern, as it was not thought to approach the thresholds for Vulnerable under any of the IUCN criteria. This species was estimated to have an extremely large range, and hence did not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence [EOO] of less than 20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population trend appeared to be stable, and hence the species did not approach the thresholds for Vulnerable under the population trend criterion (at least a 30% decline over ten years or three generations). The population size has not been quantified, but it was not believed to approach the thresholds for Vulnerable under the population size criterion (fewer than 10,000 mature individuals with a continuing decline estimated to be at least 10% over ten years or three generations, or with a specified population structure).

D. everetti is found in the western Philippines, on Balabac, Basuanga, Culion and Palawan, where it occurs in forests and open woodlands, including plantations (Kennedy et al. 2000). It may warrant listing as Near Threatened under criterion C2a(ii), if it is thought to have a small population (fewer than 10,000 mature individuals), which is inferred to be in decline owing to on-going habitat loss and degradation, although its suspected subpopulation structure does not meet the subcriteria for listing as Vulnerable (although it is assumed that the majority of mature individuals form a single subpopulation).

D. javanense (as defined following the taxonomic change, and incorporating all other forms) is found in southern India, much of Indochina, including the Thai-Malay Peninsula, Sumatra, Java, Bali and Borneo, where it occupies forested and wooded areas, including many modified habitats (del Hoyo et al. 2002). It is likely to warrant classification as Least Concern, on the basis that it is not thought to approach the thresholds for Vulnerable under any of the IUCN criteria.

Comments are invited on these suggested categories and further information would be welcomed.

  1. Desmond Allen says:

    Certainly much commoner than the sympatric Chrysocolaptes, if posted photos are to go by.

  2. Pratap Singh says:

    I have found this bird quite rare during my pursuits of recording its vocalization in South India. To me it seems to much rare bird than it is thought to be. A survey is needed to find its status and correct placement in redlist.

  3. Joe Taylor says:

    Preliminary proposals

    Based on available information and comments posted above, our preliminary proposals for the 2014 Red List would be to treat:

    D. javanense as Least Concern

    D. everetti as Near Threatened under criterion C2a(ii)

    There is now a period for further comments until the final deadline of 31 March, after which recommended categorisations will be put forward to IUCN.

    The final Red List categories will be published on the BirdLife and IUCN websites in mid-2014, following further checking of information relevant to the assessments by both BirdLife and IUCN.

  4. Andy Symes says:

    Recommended categorisations to be put forward to IUCN

    Following further review, there have been no changes to our preliminary proposals for the 2014 Red List status of these species.

    The final categorisations will be published later in 2014, following further checking of information relevant to the assessments by BirdLife and IUCN.
