Upper Magdalena Tapaculo Scytalopus rodriguezi
BirdLife Species Champion Become a BirdLife Preventing Extinctions Programme Supporter
For information about BirdLife Species Champions and Species Guardians visit the BirdLife Preventing Extinctions Programme.

Justification
This newly described species has a small population and a very small, severely fragmented range at two locations. Its range and population are likely to be declining because of continuing habitat destruction. It is therefore classified as Endangered.

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
c. 11 cm. A typical Scytalopus tapaculo, predominantly slate-grey all over with some buff-brown barring on the belly. Similar spp lacks distinguishing plumage features. Best identified on voice. Voice the song is amongst the simplest of any Scytalopus, consisting of a single note repeated at a pace of 4-5 per second usually given in bouts of 2-5 phrases.

Distribution and population
Scytalopus rodriguezi was recently described from the head of the Magdalena Valley on the east slope of the Cordillera Central mountains of Colombia. It is known from two locations, the Finca Merenberg Natural Reserve, San Agustín municipality, Huila department, and Serranía de las Minas, a ridge 15 km SSE of Finca Merenberg. It was hypothesised that the species may Scytalopus rodriguezi was recently described from the head of the Magdalena Valley on the east slope of the Cordillera Central mountains of Colombia. It is known from two locations, the Finca Merenberg Natural Reserve, San Agustín municipality, Huila department, and Serranía de las Minas, a ridge 15 km SSE of Finca Merenberg. It was hypothesised that the species may also occur on the East Andes side of the valley; this seems to be supported by the recent re-examination of a museum specimen collected at La Palma, Huila, which is consistent with rodriguezi based on plumage and biometrics (T. Donegan in litt. 2006). The species's range is believed to be very small, with its stronghold centred on Serranía de las Minas. Much habitat at suitable elevations has already been cleared with an estimated 169 km2 remaining and deforestation continues, suggesting that the species may be declining rapidly. Several records of a Scytalopus species in the Serranía de los Yariguíes are thought to relate to either a new population of this species (representing a 600 km northward range extension), or an undescribed species or subspecies of tapaculo (T. Donegan in litt. 2007, D. Willis in litt. 2007).

Population justification
The population is estimated to be in the band 2,500-9,999 individuals in total, equating to 1,667-6,666 mature individuals, rounded here to 1,500-7,000 individuals.

Trend justification
A rapid and ongoing population decline is suspected, based on rates of habitat loss at the elevations from which the species has been recorded within its very small range.

Ecology
It inhabits dense understorey of primary humid forest at elevations of 2,000-2,300 m. It is frequently heard but rarely seen. Individuals move inconspicuously within 50 cm of or on the ground. It feeds on small insects.

Threats
Deforestation is the principal threat to the species, at least in the short term. Selective logging, forest clearance to create pasture, and habitat degradation owing to trampling by free roaming livestock are the main drivers of its decline. Clearance in places of hundreds of mature oak and other hardwoods has drastically changed the forest physiognomy.

Conservation Actions Underway
It is known from the Finca Merenberg Natural Reserve. However, forest within this reserve continues to be degraded and cleared. The species's stronghold, Serranía de las Minas, is unprotected, but a joint partnership between the national parks authority and Fundación ProAves aims to establish a protected area here. Conservation Actions Proposed
Conduct further surveys to confirm the species presence on the East Andes side of the valley. Provide further protection against forest clearance within the existing Finca Merenberg Natural Reserve. Continue lobbying for Important Bird Area status for the area and the establishment of a protected area at Serranía de las Minas.
