Justification of Red List Category
Based on a model of future deforestation, it is suspected that the population of this species will decline rapidly over the next three generations, and it has therefore been uplisted to Vulnerable.
The global population size has not been quantified, but this species is described as 'uncommon' (Stotz et al. 1996).
This species is suspected to lose 22.1-23.5% of suitable habitat within its distribution over three generations (20 years) based on a model of Amazonian deforestation (Soares-Filho et al. 2006, Bird et al. 2011). Given the susceptibility of the species to hunting and/or trapping, it is therefore suspected to decline by ≥30% over three generations.
Nothocercus nigrocapillus is known from the eastern slopes of the Andes in north-central South America. The range of the nominate subspecies extends from central Peru to Bolivia, with the subspecies cadwaladeri restricted to north-west Peru (del Hoyo et al. 1992).
This is a little-known species of mainly subtropical, but also temperate, humid forests of the east Andes. It occurs from 2,000-3,000 m. It is thought to be omnivorous, and has been seen feeding on fallen bamboo seeds (del Hoyo et al. 1992).
Projected deforestation is the primary threat affecting this species (Soares-Filho et al. 2006, Bird et al. 2011). Past clearance has been known to cause severe erosion and landslides in its montane range (del Hoyo et al. 1992), and so it is likely these events will increase in frequency.
Conservation Actions Underway
None is known.
Conservation Actions ProposedExpand the protected area network to effectively protect IBAs. 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. Conservation on private lands, through expanding market pressures for sound land management and preventing forest clearance on lands unsuitable for agriculture, is also essential (Soares-Filho et al. 2006).
32-35 cm. Medium-sized, brown tinamou. Dark head, with generally paler underparts occasionally showing heavy barring.
