Data Zone
Justification of Red List category
This species has an extremely 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). The population size is very large, and hence does not 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). 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). For these reasons the species is evaluated as Least Concern.
Population justification
The population is thought to number around 300,000 mature individuals (Santini et al. 2019); it is here placed in the band 100,000-499,999 mature individuals.
Trend justification
The population trend has not been estimated directly. Forest within the range has been lost at a rate of c. 4% over three generations (16.5 years; Global Forest Watch 2020). Apart from habitat loss, the species is threatened by hunting and trapping (A. Lees in litt. 2011, Cabot et al. 2020). Therefore, the rate of population decline may be greater than the rate of forest loss alone, but is unlikely to exceed 20% over three generations.
Crypturellus duidae is a little-known species occurring in Brazil, Colombia, Peru and Venezuela. It exists in disjunct populations. The population in east-central Colombia is uncommon to very rare, while the population in south Venezuela can be locally abundant (del Hoyo et al. 1992, Restall et al. 2006).
The species inhabits dense tropical rainforest and forest edge, as well as open, bushy woodland (Cabot et al. 2020). It is known from up to 200 m in Venezuela and up to 500 m in Colombia (del Hoyo et al. 1992).
The species is threatened by habitat loss and hunting (A. Lees in litt. 2011, Cabot et al. 2020). However, the species is currently not at imminent risk because human population density and infrastructure are low within its remote range (Cabot et al. 2020).
Conservation Actions Underway
None is known.
Conservation Actions Proposed
Expand 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).
28-31 cm. Smallish, brown tinamou. Rufescent brown with lighter, ochraceous underparts and a white throat. Female has buff barring on wing-coverts. Grey legs.

Cinereous Tinamou C. cinereus, Little Tinamou C. soui and Undulated Tinamou C. undulatus are all duller and show little or no barring. Voice Slow, monotone whistle with a brief break near the beginning.
