Archived 2020 topic: Black-capped Parakeet (Pyrrhura rupicola): revise global status?

BirdLife species factsheet for Black-capped Parakeet

Black-capped Parakeet (Pyrrhura rupicola) occurs in the lowlands of south-eastern Peru and adjacent western Brazil and northern Bolivia. It inhabits humid lowland terra firme and várzea forest as well as forest edge (del Hoyo et al. 1997, Collar et al. 2020). The species is fairly common (Stotz et al. 1996, Collar et al. 2020). Based on density estimates of 3-5 pairs/km2 (Collar et al. 2020) and assuming that 10% of the area of mapped range (total of c. 500,000 km2) is occupied by the species, the global population may number 300,000-500,000 mature individuals. To account for uncertainty in the estimate, the population is here tentatively placed in the band 100,000-499,999 mature individuals.

The only threat known to Black-capped Parakeet is habitat loss. A study of deforestation in the Amazon projected rapid forest loss within the range of up to 15% over three generations, which was feared to be exacerbated by the impacts of trapping (Soares-Filho et al. 2006, Bird et al. 2011, A. Lees in litt. 2011). However, it appears that the species is not affected by trapping (Collar et al. 2020). Moreover, new information regarding the rate of forest loss suggests that the projected losses of 15% over three generations were overestimated, as much pristine habitat persists within the range (Tracewski et al. 2016, Collar et al. 2020, Global Forest Watch 2020). 

Black-capped Parakeet is currently listed as Near Threatened, approaching the threshold for listing as threatened under Criterion A3c, based on projections of rapid habitat loss in the future. However, new information regarding trends in habitat availability suggests that the species may warrant a change in Red List status. Therefore, it will be re-assessed against all Red List criteria:

Criterion A – The population trend has not been estimated directly. Forest loss within the range has been small over the last ten years (<5%; Tracewski et al. 2016, Global Forest Watch 2020; one generation length being 2.6 years; Bird et al. 2020). The species is not thought to be threatened by trade (Collar et al. 2020). Therefore, in the absence of evidence for any declines or substantial threats, the species is assessed as stable and thus may be considered Least Concern under Criterion A.

Criterion B – The Extent of Occurrence (EOO) for this species is 609,000 km2. This is too large to warrant listing as threatened under Criterion B1, and Black-capped Parakeet qualifies for Least Concern under this criterion. The Area of Occupancy (AOO) has not been quantified according to IUCN guidelines (IUCN Standards and Petitions Committee 2019), and so the species cannot be assessed against Criterion B2.

Criterion C – The population of Black-capped Parakeet is thought to number 100,000-499,999 mature individuals. This is too large to warrant listing as threatened under Criterion C, and thus the species is considered Least Concern under this criterion.

Criterion D – The population size and range are too large to approach the threshold for Vulnerable. Therefore, Black-capped Parakeet may be listed 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 suggested that Black-capped Parakeet (Pyrrhura rupicola) be listed as Least Concern. We welcome any comments on the proposed listing.

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. By submitting a comment, you confirm that you agree to the Comment Policy.

*Bird generation lengths are estimated using the methodology of Bird et al. (2020), as applied to parameter values updated for use in each IUCN Red List for birds reassessment cycle. Values used for the current assessment are available on request. We encourage people to contact us with additional or improved values for the following parameters; adult survival (true survival accounting for dispersal derived from an apparently stable population); mean age at first breeding; and maximum longevity (i.e. the biological maximum, hence values from captive individuals are acceptable).

  1. Red List Team (BirdLife International) says:

    Global Forest Change data on tree cover loss up to 2019 have now been released and made available via Global Forest Watch. Based on these data, over ten years approximately 3.0% of tree cover with 75% canopy cover was lost from within the species’s range (Global Forest Watch 2020). This does not affect the above assessment under Criterion A.

  2. Red List Team (BirdLife International) says:

    The window for consultation is now closed. We will analyse and interpret the new information and post a preliminary decision on this species’s Red List status on this page in early July.

    Thank you,
    BirdLife Red List Team

  3. Red List Team (BirdLife International) says:

    Preliminary proposal

    Based on available information, our preliminary proposal for the 2020 Red List would be to adopt the proposed classification 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 2020 Red List categories will be published on the BirdLife and IUCN websites in December 2020/January 2021, following further checking of information relevant to the assessments by both BirdLife and IUCN.

  4. Red List Team (BirdLife International) says:

    Recommended categorisation to be put forward to IUCN

    The final categorisation for this species has not changed. Black-capped Parakeet is recommended to be listed as Least Concern.

    Many thanks for everyone who contributed to the 2020 GTB Forum process. The final 2020 Red List categories will be published on the BirdLife and IUCN websites in December 2020/January 2021, following further checking of information relevant to the assessments by both BirdLife and IUCN.
