VU
Rusty-headed Spinetail Synallaxis fuscorufa

Justification
This species has a small range and population, which is fragmented and declining owing to habitat destruction caused by illegal agriculture, logging and burning. Intensification of these pressures, and hence increased rates of population decline have led to its uplisting to Vulnerable. It may even warrant uplisting to Endangered once more detailed information on rates of forest loss becomes available.

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
17 cm. Large orange-rufous spinetail. Head, neck and upper breast orange-rufous, as are wings and long tail. Back and flanks greyish-olive. Black throat patch usually concealed. Bill and legs dark. Similar spp. None within restricted range. Voice Call an oft-repeated nasal dit-dit-du.

Distribution and population
Synallaxis fuscorufa is endemic to the Santa Marta mountains of north Colombia, with records from Cesar, Guajira and Magdalena departments. It has a small range, and its population size is currently unknown (Renjifo et al. 2002). It is described as common in humid shrubby forest borders, overgrown clearings and forest undergrowth.

Population justification
The species is fairly common within its tiny range and its population is estimated to number 2,500-9,999 mature individuals. This equates to 3,750-14,999 individuals in total, rounded here to 3,500-15,000 individuals. The population estimate requires confirmation.

Trend justification
A rapid population decline is suspected based on rates of habitat loss estimated from time series satellite images (Renjifo et al. 2002).

Ecology
Synallaxis fuscorufa is found in the undergrowth of montane forests, as well as along forest edges, in altered habitat and in shrubs in open habitats (Hilty and Brown 1986, Renjifo et al. 2002). It is principally recorded at 2,000-3,000 m, but occasionally to 900 m (Hilty and Brown 1986). Its behaviour is similar to that of other Synallaxis species. It feeds as it moves energetically within shrubs and small branches principally 0.5-7 m above the ground. It is observed in pairs or family groups, which accompany mixed-species flocks. Breeding seems to occur between January and June (Renjifo et al. 2002).

Threats
Habitats are seriously threatened by illegal agricultural expansion, logging and burning (Dinerstein et al. 1995, Renjifo et al. 2002). Only 15% of the sierra's original vegetation is currently unaltered (Stattersfield et al. 1998), and the species has lost 59% of its habitat (Renjifo et al. 2002). The best known area, the Cuchilla de San Lorenzo, is not within the Sierra Nevada de Santa Marta National Park (Renjifo et al. 2002).

Conservation Actions Underway
It is found within the Sierra Nevada de Santa Marta National Park (Renjifo et al. 2002). Research is currently being carried out on the conservation of habitats for birds resident to the sierra (Renjifo et al. 2002). Conservation Actions Proposed
Increase the area of suitable habitat that has protected status, in part by increasing the limits of the Sierra Nevada de Santa Marta National Park to include the whole altitudinal gradient within the three departments (Renjifo et al. 2002). Estimate the population size, particularly in Guajira and Cesar (Renjifo et al. 2002).
