Orinoco Softtail Thripophaga cherriei

Justification
This species is only known from the type-locality. Shifting agriculture is practised in this general area, but is probably not currently impacting on the known population (Collar et al. 1992). This combination of a very small range and some potential threat qualifies it as Vulnerable.

Taxonomic source(s)
SACC. 2006. A classification of the bird species of South America. Available at: #http://www.museum.lsu.edu/~Remsen/SACCBaseline.html#.

Identification
18 cm. Brown, streaked furnariid. Rufous-brown upperparts, richest on wings and tail. Faint buff-white supercilium. Orange chin patch. Rest of underparts olive-brown with numerous narrow, buffy-white streaks. Similar spp. Speckled Spinetail Cranioleuca gutturata has chestnut crown, pale breast with dusky spots and lacks orange chin patch. Voice Undescribed.

Distribution and population
Thripophaga cherriei was known from just six specimens taken in 1899 and 1970, and observations since 1999 of up to three individuals (Colvee 2000, D. Willis in litt. 2003), all along the caño Capuana, a low-lying affluent of the upper río Orinoco in Venezuela. In 2007, a survey of the area found it to be common along the caños Capuana, Guacharaca and Grulla as well as along the nearby río Orinoco (Lentino et al. 2007). There is also a possible historic record from Junglaven on the río Ventuari, but there have been no further records at this site (D. Willis in litt. 2006). There are no other records despite surveys in adjacent areas (Colvee 2000). It could occur over a much larger area as its habitat appears to be widespread, but if this is the case it is perhaps surprising that its loud call has not led to its discovery elsewhere.




Population justification
The population size is preliminarily estimated to fall into the band 250-999 mature individuals. This equates to 375-1,499 individuals in total, rounded here to 350-1,500 individuals. However, it may prove to be much more abundant: in 2007, 25 individuals were recorded along 4 km of creeks (Lentino et al. 2007). 

Trend justification
No data are available to confirm population trends and there have been few recent records. However, a population decline is suspected owing to the loss of habitat through shifting cultivation.

Ecology
It occurs at c.100 m altitude, in the understorey of riverine and humid forest, adjacent to rivers (Colvee 2000). Territories appear to be small, occupying 30-50 m along a creek (Lentino et al. 2007). It has been found in flooded creek-side forests, as well as riverine scrub (Lentino et al. 2007). Other aspects of its ecology are very poorly known.



Threats
The principal threat appears to be loss of habitat through unsustainable, shifting cultivation practices (Colvee 2000).


Conservation Actions Underway
The Sipapo Forest Reserve encompasses its known distribution, but provides little effective protection for riverside habitats (Colvee 2000). Conservation Actions Proposed
Survey to assess its distribution and population size. Assess its ecological requirements. Improve protection of riverine habitats in Sipapo Forest Reserve. Grant protected status to any other occupied sites outside Sipapo Forest Reserve.
