Archived 2017 topics: Blue-breasted Parrot (Pionus reichenowi): uplist from Least Concern to Vulnerable?

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 this species as part of the 2017 Red List update this post remained open and the date of posting was updated.

BirdLife species factsheet for Blue-breasted Parrot

Blue-breasted Parrot is endemic to east Brazil, from Alagoas to Espírito Santo. The species is listed as Least Concern. The global population size has not been quantified but it is not thought to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). The population is suspected to be in decline owing to ongoing habitat destruction and fragmentation. The species’s Extent of Occurrence is estimated to be 243,000 km2.

In the Brazilian Red List assessment for birds (MMA 2014) this species is listed as Vulnerable under C2a(i). The total population size is estimated at <10,000 mature individuals with <1,000 mature individuals in each subpopulation. The species’s population is in continuing decline owing to a deterioration in habitat quality, and is considered to be in a critical condition in the Pernambuco Center of Endemism. The species’s assessment on the Brazilian Red List can be accessed here.

Confirmation that the species’s population size is <10,000 mature individuals, that the population is in continuing decline and that there are <1,000 mature individuals in each subpopulation would likely qualify the species for Vulnerable under criterion C2a(i). Comments on the proposed uplisting are welcome.

  1. 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 preliminary proposal for the 2017 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 of 4 August, 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 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.
