Archived 2017 topics: Vinaceous-breasted Amazon (Amazona vinacea): downlist from Endangered 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 Vinaceous-breasted Amazon

Vinaceous-breasted Amazon is found in Paraguay, southern Brazil and in north-east Argentina. The species is listed as Endangered under C2a(i). The population has been estimated at 600-1,700 mature individuals in 2009. A rapid and on-going population decline is suspected owing to illegal nest poaching, habitat destruction and persecution as a crop pest. The largest subpopulation has been estimated to be 50-249 mature individuals.

In the Brazilian Red List assessment for birds (MMA 2014) this species is listed as Vulnerable under C1. The population is estimated to be <10,000 mature individuals with an estimated continuing decline of 10% in three generations due to capture and habitat loss. The species’s assessment on the Brazilian Red List can be accessed here.

Up-to-date information is requested on the species’s population size, trend and subpopulation structure. Confirmation of a population of 2,500 or more mature individuals and/or more than 250 individuals in each subpopulation would likely qualify the species for downlisting to Vulnerable under Criterion C. Comments on the proposed downlisting are welcome.

  1. Guyra Paraguay recently finished a second project funded by LPF with a focus on the Vinaceous-breasted Amazon. During the latest project, Guyra Paraguay carried out fieldwork at three of the remaining key sites of the species in Paraguay where still some Atlantic forest is left. During the fieldwork the population of the Vinaceous-breasted Amazon was monitored and compared with data of previous years. One of the fieldwork trips formed part of the regional Vinaceous-breasted Amazon census, which was carried out simultaneously in Brazil, Argentina and Paraguay. Based on all fieldwork data, a total of 133 individuals were counted, which is similar to the total
    count observed during the previous project during 2013-2014. However, less than what was found by Kockle et al. 2007. Although there are a number of other sites with reports, counts are low and over all it is not believed that the population in Paraguay surpasses 250 individuals. I believe the same can be said for Argentina. Only Brazil has still a relative large population, of the 3.133 birds counted during the regional census in 2015, the vast mayority were found in Brazil. But also here the populationis rather scattered in Atlantic forest remnants.

    Downlisting the species does not sound like a good plan, it is too soon. The species still has a fragil population and its key habitat is still under threat, besides, illegal trafficing still affects the species population as wel. In Paraguay the population is very low and can go extinct without monitoing and conservation action. Of the few sites where the species is known to breed, reports of nests eing poached have been received.

    Feel free to contact me for further and perhaps more detailed information.

  2. We have the past 15 years observed A.vinacea flocks in eight locations (Araçuai, Almenara, Itinga, Jequitinhonha, Pedra Azul, Poté, Carlos Chagas and Umburatiba) in northeastern Minas Gerais (it seems that the current northern limit of the distribution of the species) . How not conducted a census in the region, we can not accurately indicate a population size for the species, but due to the high number of hours of field in these locations and the number of individuals identified in flocks, we believe that the population of breast-purple parrots in both valleys of the Jequitinhonha and Mucuri not exceed 200 individuals (average 10-25 individuals by location, including mature not). We detected intense catch of the species in the Fazenda Poço Preto well in Itinga. The bird was nearly extinct in the state of Bahia.

  3. Our last best count in Argentina was minimum 262, maximum 314, across all known localities except Campo Viera, on March 25th 2016. In Campo Viera all reports indicate <20 individuals in the last 15 years.

    We continue to find very low nest success in Argentina, even in protected areas. Availability of nest sites continues to decline because most of the nesting area is on farms, which are still undergoing forest clearing. Nest trees and potential nest trees are removed by people, or fall, and are not replaced. Recent interviews (2015, 2016) suggest that nest poaching continues to be a problem in Argentina.

    To Arne's comment, I will add that an unknown (but potentially large) proportion of the total censused individuals (in Brazil, Argentina, and Paraguay) are likely immature/non-breeders.

    Some (perhaps many) of the Vinaceous Parrots in Argentina move across the border to Brazil, so that they could potentially be counted twice.

    I suggest it is premature to downlist Vinaceous Parrot at present.

  4. 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.

  5. Fabio Olmos says:

    A country-wide census in Brazil carried by Projeto Charão and several partners found some 4,000 birds. This is a massive drop from what was reckoned to exist just a few years ago.

  6. Hannah Wheatley (BirdLife) says:

    Preliminary proposals

    Based on available information, our preliminary proposal for the 2017 Red List would be to retain this species as EN under criterion C2a(i).

    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 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.
