Justification of Red List category
This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <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). Despite the fact that the population trend appears to be decreasing, the decline is not believed to be sufficiently rapid to approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.
Population justification
The global population size has not been quantified, but the species is described as 'fairly common' (Stotz et al. 1996). Given the number of records within its large range (per eBird 2021) it is unlikely that the population numbers below 10,000 mature individuals.
Trend justification
The population trend was reported to be stable, as the species's preference for dense forest edge and secondary growth may buffer the impact of tree cover loss (Carter 2020). However, tree cover loss has been accelerating since 2016, to a rate equivalent to 10% over three generations (Global Forest Watch 2021, using Hansen et al. [2013] data and methods disclosed therein). Moreover, the species may be subject to trapping pressure (A. Lees in litt. 2011). Therefore, while the population may have been stable until recently, it is feared that the population is now starting to decline slowly, at a rate not exceeding 10% over three generations.
Pyrrhura perlata occurs in Brazil, from west Pará and east Amazonas south to west-central Mato Grosso. It is especially common along the Rio Jiparaná, in Rondônia. The species's range extends further into north Bolivia (del Hoyo et al. 1997, Carter 2020).
This is a species of terra firme lowland rainforest. It appears to prefer dense vegetation at the forest edge and in secondary growth. The species is often observed in small groups. Its diet consists mainly of fruit, of Trema micrantha and various palms, as well as Cecropia catkins and flowers of Bertholletia excelsa and Dioclea glabra. It is known to breed from July to November in the south of its range (del Hoyo et al. 1997, Carter 2020).
The primary threat to this species is accelerating deforestation in the Amazon basin as land is cleared for cattle ranching and soy production, facilitated by expansion of the road network (Soares-Filho et al. 2006, Bird et al. 2011). While the species is tolerant of secondary growth, it is not known to occur on purely agricultural land. The species is also susceptible to hunting (A. Lees in litt. 2011).
Conservation Actions Underway
The species occurs in Campos Amazônicos, Amazônia, Juruena, Jamanxim, Rio Novo and Serra do Pardo National Parks in Brazil, and Noel Kempff Mercado National Park in Bolivia (Carter 2020). No targeted actions are known.
Conservation Actions Proposed
Accurately quantify the population size. Investigate the subpopulation structure. Quantify the impact of trapping on the population size. Monitor population trends. Monitor rates of habitat loss. Effectively resource and manage existing and new protected areas, utilising emerging opportunities to finance protected area management with the joint aims of reducing carbon emissions and maximizing biodiversity conservation. Increase market pressures for sound land management and preventing forest clearance on lands unsuitable for agriculture (Soares-Filho et al. 2006).
