LC
Highland Tinamou Nothocercus bonapartei



Justification

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). 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). 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). For these reasons the species is evaluated as Least Concern.

Population justification
The population size is suspected to fall in the range 50,000-500,000 mature individuals (Partners in Flight 2020).

Trend justification
The population has undergone a slow or non-significant decline between 1970 and 2017 (Partners in Flight 2020). The decline is thought to be caused by a combination of habitat loss and unsustainable levels of hunting (del Hoyo et al. 1992; Gomes and Kirwan 2020). Over three generations (16.8 years), about 4% of tree cover is lost within the range (Global Forest Watch 2021, using Hansen et al. [2013] data and methods disclosed therein). To account for the additional impact of hunting, the rate of population decline is therefore here tentatively placed in the band 1-19% over three generations.

Threats

The species is threatened by habitat loss and unsustainable levels of hunting (del Hoyo et al. 1992, Gomes and Kirwan 2020).
