Reviewer/s:

Butchart, S. & Taylor, J.

Contributor/s:

Lees, A.

Justification:

Based on a model of future deforestation in the Amazon basin 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.

Geographic Range [top]

Range Description:	Cranioleuca curtata is a polytypic species found in the east Andes of western South America. The nominate subspecies curtata is endemic to central Colombia, from south-east Santander south as far as Huila. Subspecies cisandina occurs south from west Caquetá, south Colombia, through east Ecuador to north Peru, where it spreads south as far as Pasco. Subspecies debilis ranges from Ayacucho and Cuzco in central Peru, south to west Santa Cruz in central Bolivia (del Hoyo et al. 2003). It has been considered generally uncommon, but is frequently overlooked and may be more abundant than records suggest (del Hoyo et al. 2003, Restall et al. 2006).

Population [top]

Population:	The global population size has not been quantified, but this species is described as 'uncommon' (Stotz et al. 1996).
Population Trend:	Stable

Habitat and Ecology [top]

Habitat and Ecology:	This is a species of montane and lower montane humid forest, and some secondary habitat. It usually ranges from 900-1,700 m. It feeds on arthropods. The only breeding information is a record of a fledgling from March in north Ecuador (del Hoyo et al. 2003).
Systems:	Terrestrial

Threats [top]

Major Threat(s):	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 [top]

Conservation Actions:	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).
