Justification of Red List category
Based on a model of future deforestation in the Amazon basin, it is suspected that the population of this species will decline by 25-30% over the next three generations, and it has therefore been uplisted to Near Threatened.
The global population size has not been quantified, but this species is described as 'uncommon' (Stotz et al. 1996).
This species is suspected to lose 27-27.8% 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). It is therefore suspected to decline by a rate approaching 30% over three generations.
Phylloscartes gualaquizae occurs in the forests of the east Andes (del Hoyo et al. 2004). In Ecuador, it ranges southwards from north Sucumbíos and west Napo; it is generally rare in the country, but fairly common at Serranías Cofán and also present in the Podocarpus National Park (del Hoyo et al. 2004, Restall et al. 2006). It is also known from San Martín, north Peru, where it is fairly common in the río Afluente region. It is thought that its distribution could extend northwards into south Colombia (del Hoyo et al. 2004).
This is a humid forest species of the montane and upper tropical forest zones in the Andean foothills. It generally remains below the cloud forest zone, occurring between 700-1,400 m (del Hoyo et al. 2004).
The primary threat to this species is accelerating deforestation in the Amazon basin, with many of its native forests threatened by logging, mining, agriculture and road building (del Hoyo et al. 2004, Soares-Filho et al. 2006, Bird et al. 2011).
Conservation Actions Underway
None is known.
Conservation Actions ProposedExpand 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).
11-12 cm. Smallish, green tyrannulet. Grey crown and forehead, with a whitish face and throat. Rest of underparts are yellow, and has olive upperparts, with some black on the wings.
