VU
Marcapata Spinetail Cranioleuca marcapatae

Justification

Based on a model of future deforestation in the Amazon basin, and its dependence on primary forest, it is suspected that the population of this species will decline rapidly over the next three generations, and it has therefore been uplisted to 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
15-16 cm. Smallish, brown ovenbird. Dull greyish face, with black around the eye and noticeably bordering the white supercilium. Forehead and crown are reddish chestnut, continuing to the upper back, wings and tail. Underparts are dull greyish. Voice Its song is described as a descending skwa, ski-ski-ski-skee-skee, tuhtuhtuh.

Distribution and population
Cranioleuca marcapatae is endemic to Cuzco, Peru, where it is present in the Machu Picchu Historical Sanctuary. Subspecies weskei occurs in the Vilcabamba Mts, and the nominate subspecies marcapatae in the Vilcanota and Carabaya ranges. It is generally uncommon (del Hoyo et al. 2003).

Population justification
The global population size has not been quantified, but this species is described as 'fairly common' (Stotz et al. (1996).

Trend justification
This species is suspected to lose 21.4-21.5% of suitable habitat within its distribution over three generations (11 years) based on a model of Amazonian deforestation (Soares-Filho et al. 2006, Bird et al. 2011). Given the susceptibility of the species to fragmentation and/or edge effects, it is therefore suspected to decline by ≥30% over three generations.

Ecology
This is a species of humid montane and elfin forest from 2,400-3,500 m, often found in Chusquea bamboo. It feeds on arthropods. A nest thought to be of this species was oval in shape, made from moss, bark and twigs and suspended from the edge of a branch 9 m from the ground. Fledglings have been recorded in December, April and May (del Hoyo et al. 2003).

Threats
The primary threat to this species is accelerating deforestation; it is thought to be particularly susceptible to fragmentation and edge effects (Soares-Filho et al. 2006, Bird et al. 2011, A. Lees in litt. 2011).

Conservation Actions Underway
None is known.

Conservation Actions Proposed

Expand the protected area network to effectively protect IBAs. Effectively resource and manage existing and new protected areas, utilising emerging opportunities to finance protected area management with the joint aims of reducing carbon emissions and maximizing biodiversity conservation. Conservation on private lands, through expanding market pressures for sound land management and preventing forest clearance on lands unsuitable for agriculture, is also essential (Soares-Filho et al. 2006).
