Justification of Red List category
Based on rates of deforestation in the Amazon basin, and its dependence on primary forest, it is suspected that the population of this species is declining moderately rapidly over three generations. It is therefore listed as Near Threatened.
Population justification
The global population size has not been quantified, but this species is described as 'fairly common' (Stotz et al. 1996).
Trend justification
The species is described as very sensitive to habitat degradation (ICMBio 2018). Even though there are no exact data on the population trend, it is observed less frequently in disturbed and converted habitats (ICMBio 2018). The population is believed to be in decline as a consequence of the loss, fragmentation and degradation of forests in its range.
Over the past three generations (10.9 years), 9% of tree cover has been lost within the range; since 2017, this rate has been increasing to 11% over three generations (Global Forest Watch 2023, using Hansen et al. [2013] data and methods disclosed therein). Even though the species may also be found in tall secondary growth it is strictly dependent on continuous forest cover (ICMBio 2018, Schulenberg 2020). To account for additional impacts of forest degradation, fragmentation and selective logging, it is precautionarily suspected that population declines may be up to twice as high as the rate of tree cover loss alone. Therefore, declines are here placed in the band 10-19% over the past three generations, and in the band 20-29% over the next three generations into the future.
Capito dayi occurs in central South America. It is found in the Madeira-Tocantins interfluvium in Amazonian Brazil, with a range stretching south-west to Rondônia, Mato Grosso, as well as Beni and Santa Cruz in northern and north-eastern Bolivia.
It inhabits lowland tropical forest up to 550 m, foraging mainly on fruits and arthropods in the canopy (del Hoyo et al. 2002).
The primary threat to this species is accelerating deforestation in the Amazon basin as land is cleared for cattle ranching, soy production and timber harvesting, facilitated by expansion of the road network (Soares-Filho et al. 2006, Bird et al. 2011). It is not naturally rare, but is likely to be especially vulnerable to this change because of its dependence on primary forest (del Hoyo et al. 2002, A. Lees in litt. 2011, ICMBio 2018).
Conservation Actions Underway
The species occurs in several protected areas across its range, including Noel Kempff Mercado National Park in Bolivia, and Rio Novo, Jamanxim and Juruena national parks in Brazil (del Hoyo et al. 2002, IMCBio 2018). It is listed as Vulnerable at the national level in Brazil (ICMBio 2018).
Conservation Actions Proposed
Survey to quantify the population size and trend. Research the species' ecology and behaviour. Research the extent and impact of habitat fragmentation and degradation. Monitor the population trend. Monitor rates of habitat loss.
Expand the protected area network to effectively protect key sites. Effectively manage protected areas, utilising emerging opportunities to finance protected area management with the joint aims of reducing carbon emissions and maximizing biodiversity conservation. Incentivise conservation on private lands through expanding market pressures for sound land management and preventing forest clearance on lands unsuitable for agriculture (Soares-Filho et al. 2006).
16-17 cm. Smallish, black-and-white barbet. Named for the black girdle stretching across its white underparts. Crimson cap and cinnamon throat. Female has a black cap. Voice Its song is a series of hooo or rroh notes, repeated for up to 10 seconds.
