Justification of Red List category
This species has a very 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. The species is described as 'uncommon', though it may be overlooked due to its inconspicuousness (Stotz et al. 1996, Snow and Sharpe 2020).
Trend justification
Due to its sensitivity to forest loss and fragmentation, the species is suspected to be in decline as a consequence of habitat loss. Within the range, tree cover has been lost at a rate of 6% over the past three generations (13 years); since 2016 this has been increasing to a rate equivalent to 9% over three generations (Global Forest Watch 2022, using Hansen et al. [2013] data and methods disclosed therein). In view of the species' low tolerance of forest loss, it is suspected that population declines exceed the rate of tree cover loss; they are here tentatively placed in the band 10-19% over three generations.
Carpornis cucullata is restricted to south-east Brazil (Espírito Santo south to Rio Grande do Sul) (Sick 1993, Ridgely and Tudor 1994, Parker et al. 1996).
The species inhabits lowland and montane evergreen forests and palm groves at elevations up to 1,600 m. In the north of its range (Espírito Santo and Rio de Janeiro), it is almost entirely restricted to montane forest. It favours large patches of pristine forest and appears sensitive to habitat fragmentation (Snow and Sharpe 2020, G. N. Mauricio in litt. 2022). It feeds mainly on fruits (Snow and Sharpe 2020).
Agricultural conversion and deforestation for mining and plantation production historically threatened its lowland forests (Fearnside 1996), having destroyed large areas of the original lowland habitat within the range. Current key threats are urbanisation, industrialisation, agricultural expansion, colonisation and associated road-building (Dinerstein et al. 1995).
Conservation Actions Underway
It occurs in several protected areas, including Serra dos Órgãos National Park, Augusto Ruschi Biological Reserve and Intervales and Serra do Mar State Parks (del Hoyo et al. 2004).
Conservation Actions Proposed
Quantify the population size. Search for the species in potentially suitable habitat at new sites. Study its ecology and its ability to persist in degraded and fragmented habitats. Monitor the population trend. Effectively protect and manage areas where the species occurs.
