Data Zone
Justification of Red List category
This species is suspected to undergo moderately rapid declines on the basis of accelerating rates of habitat loss. It is therefore assessed as Near Threatened.
Population justification
The global population size has not been quantified, but the species is described as uncommon in Colombia and as scarce and local in Venezuela (del Hoyo et al. 2020, see also eBird 2023).
Trend justification
The population trend has not been quantified, but declines are suspected owing to habitat fragmentation and loss of suitable nesting sites (del Hoyo et al. 2002, 2020).
Even though data on its habitat requirements are scarce, this species appears to show a stronger preference for mature forest habitat (per del Hoyo et al. 2020). Over the past three generations (17.9 years), 12% of tree cover has been lost within the range; from 2017 onward this has been accelerating to a rate equivalent to 16% over three generations (Global Forest Watch 2023, using Hansen et al. [2013] data and methods disclosed therein). These values however do not account for the additional impacts of forest degradation and fragmentation. Precautionarily it is therefore suspected that overall habitat loss (i.e. the combined effect of tree cover loss, forest fragmentation and degradation) exceeds the rate of tree cover loss by half, suggesting an overall rate of habitat loss of 18% over the past three generations and accelerating to 24% over three generations from 2017 onward. Assuming that population declines in this forest-dependent species are roughly equivalent to the rate of habitat loss, population declines are here placed in the band 10-19% over the past three generations, with the rate accelerating to 20-29% from 2017 onward.
The species occurs in the lowland and foothills of northern Colombia and northwestern Venezuela.
The species inhabits tall, humid forests in the lowlands and foothills up to 1,700 m (del Hoyo et al. 2020). It feeds on fruits, insects and small vertebrates, but its ecology is not well known (del Hoyo et al. 2020).
The major threats to this species are the loss, degradation and fragmentation of its habitat through agricultural expansion and logging. It is not known whether this species is being hunted, though it cannot be ruled out given that its congeners are generally considered susceptible to hunting (del Hoyo et al. 2020, see also UNEP-WCMC 2023).
Conservation Actions Underway
No targeted actions are known.
Conservation Actions Proposed
Survey to quantify the population size. Research the species' ecology and habitat requirements. Research threats, including the impacts of habitat fragmentation and degradation on the population size, and the potential impact of hunting. Monitor the population trend. Protect areas of suitable habitat.
