Justification of Red List Category
This species is considered Near Threatened as it has been recorded at only a handful of sites, and appears to be rare and patchily distributed. It may therefore have a moderately small population. Although this may currently be stable, future loss or degradation of its forest habitat could seriously impact the species. Conversely, if surveys locate additional populations in surrounding areas, it may qualify for downlisting to Least Concern.
In the absence of sufficient data, this species is suspected to have a moderately small population, preliminarily estimated at 10,000-19,999 individuals, as it only occurs at a few locations and has been described as 'uncommon'. This estimate equates to 6,667-13,333 mature individuals, rounded here to 6,000-15,000 mature individuals.
This species is suspected to lose 5.8-18.9% of suitable habitat within its distribution over three generations (18 years) based on a model of Amazonian deforestation (Soares-Filho et al. 2006, Bird et al. 2011). It is therefore suspected to decline by <25% over three generations.
Turdus haplochrous is known from only a few localities in south-east Beni and west Santa Cruz, north Bolivia (Ridgely and Tudor 1994, White et al. 1995), and is apparently rare and local even within suitable habitats.
It occurs in seasonally flooded riverine forest (várzea), gallery forest, semi-open forest and semi-deciduous woodland at 250-350 m (White et al. 1995, D. Lane in litt. 2011).
The habitat occupied by this species is widespread in the Bolivian lowlands and is not currently subject to particular threat (White et al. 1995). However, the very small and patchy range implies that future changes in land-use could rapidly cause an increase in threat status.
