Population justification: The population size of this species is not known, but it is generally considered to be rare, and is known only from a small number of localities (Pinheiro and Dornas 2009, Dornas et al. 2018). However, it does not appear to be uncommon in Tocantins (T. Dornas in litt. 2020).
Surveys in Serra do Cachimbo, Pará in 2002 recorded 9 individuals per 100 survey hours in montane forest, and 14 individuals per 100 survey hours in campinarana (Pacheco and Olmos 2005). Six individuals were recorded in a forest fragment in Tocantins (Olmos et al. 2004).
Based on the minimum and first quartile densities of species in the same subfamily (1 and 6.5 individuals per km2, respectively), the projected area of tree cover within the species's range in 2021 (865,475 km2; Global Forest Watch 2021), and assuming that 5-10% of the forest area is occupied, the population size is tentatively suspected to fall within the range 43,000 - 563,000 individuals, roughly equating to 28,000 - 376,000 mature individuals.
The subpopulation structure is not known, but given the degree of habitat fragmentation within the range, there are likely to be multiple subpopulations.
Trend justification: The species's population size is inferred to be declining due to ongoing habitat loss. Surveys in APA Tucuruí, Pará from 2005-2007 did not record the species, perhaps indicating local extinction due to extensive landscape-scale habitat loss and fragmentation (Henriques and Dantas 2009). The species was also not recorded during five months of surveys in Paragominas, Pará in 2010-2011 (Lees et al. 2012), and it has been unrecorded since 1967 in the metropolitan region of Belem (Moura et al. 2014). There has been a reduction of species records in riparian forests along the Tocantins since the construction of hydroelectricity plants, and further plants are planned for the Araguaia, Xingu and Tapajós rivers (Dornas et al. 2018).
Remote sensing data on tree cover loss within the species's range indicates that approximately 13% of tree cover with at least 50% canopy cover was lost over the past decade (Global Forest Watch 2021). Extrapolating forwards based on average annual areas of loss since 2000, or since 2016, it is projected that 15-19% of tree cover with at least 50% canopy cover may be lost from the species's range.
This species occurs in riparian forest, which is unlikely to be cleared for agriculture, but is also threatened by the planned construction of hydro-electricity plants (Dornas et al. 2018). Although the species also occurs in more open habitats such as savanna, it appears to prefer intact habitats (Dornas et al. 2018), and seems to have disappeared from landscapes with high levels of deforestation (Henriques and Dantas 2009), so its population size is assumed to be declining in line with tree cover loss. Furthermore, an analysis of the impact of disturbance on forest species in Pará found that in private lands or sustainable-use reserves, the impact of disturbance on biodiversity was equivalent to that of an additional 51% loss of forest, on average (Barlow et al. 2016).
The population size is therefore suspected to have undergone a reduction of 13-19% over the past ten years, and is projected to undergo a reduction of 15-29% over the next ten years.
