Archived 2018 topic: Campo Miner (Geositta poeciloptera): uplist from Vulnerable to Endangered?

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 the species as part of the 2018 Red List update this post was kept open. A decision has now been made and this topic is now closed.

BirdLife species factsheet for Campo Miner

Campo Miner occurs within interior south-central Brazil (from São Paulo, where it is now considered extinct, north to Minas Gerais, Goiás and Mato Grosso), north-east Bolivia (north-east Santa Cruz in the Serranía de Huanchaca), and a specimen was collected in Paraguay in 1938 (J. M. Bates in litt. 1999, Ridgely and Tudor 1994, Sick 1993). Although it may be locally common in places, it is generally uncommon and has declined as large areas of cerrado are converted for agriculture, cattle-ranching and plantations. It has therefore been listed as Vulnerable under Criteria A2c+3c+4c.

In the Brazilian Red List assessment for birds (MMA 2014) this species is listed as Endangered under Criterion B2ab (ii, iii), based on its fragmented distribution, a continuing decline caused by wildfires, and a calculated area of occupancy of 132km2. The species’s assessment on the Brazilian Red List can be accessed here.

Up-to-date information is requested on the species’s area of occurrence, level of fragmentation and population trend. Confirmation that the area of occurrence is smaller than 500 km2 and that the population is severely fragmented and declining would likely qualify the species for uplisting to Endangered under Criterion B2ab. Comments on the proposed uplisting are welcome.

  1. Rob Clay says:

    There have been no further records in Paraguay since the 1938 specimen. Although there has been no ornithological fieldwork in this area in recent years, habitats in the general area have been greatly modified.

  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.

    Preliminary proposals

    Based on available information, our proposal for the 2017 Red List would be to pend the decision on this species and keep this discussion open until 2018, while leaving the current Red List category unchanged in the 2017 update.

    Final 2017 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.

  4. Claudia Hermes (BirdLife International) says:

    Based on available information, our preliminary proposal for the 2018 Red List would be to list:
    Campo Miner as Vulnerable under criterion A2c+3c+4c.
    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 the initial proposal.
    The final 2018 Red List categories will be published on the BirdLife and IUCN websites in November, following further checking of information relevant to the assessments by both BirdLife and IUCN.
