Identification information: 17-18 cm. Chunky, dusky green parrotlet. Overall green with dusky brown wings, whitish tips to coverts and orange tips to two outer median coverts. Female and immature have green wing-coverts with black bases. Similar spp. Scarlet-shouldered Parrotlet T. huetii shows conspicuous red (and sometimes yellow) on wings. Cobalt-winged Parakeet Brotogeris cyanoptera has pointed tail and blue wings. Voice In flight, two or three rasping raah-reh notes, with lower first note. Apparently silent when perched. Hints Moves silently around canopy, and has non-undulating flight with deep, steady wingbeats.

Red List Category & Criteria: Vulnerable A3c; C2a(i); D1 ver 3.1
Year Published: 2016
Date Assessed: 2016-10-01
Assessor(s): BirdLife International
Reviewer(s): Butchart, S. & Symes, A.

Facilitator/Compiler(s): Benstead, P., Isherwood, I., Sharpe, C J, Stuart, T., Symes, A.
Justification:
This species apparently occurs very locally and at low densities in a declining habitat. Its population is likely to be small and declining, with very small subpopulations at each known locality. It therefore qualifies as Vulnerable.

Geographic Range [top]

Range Description:Touit stictopterus occurs disjunctly through Colombia (Cundinamarca, Meta, Cauca), Ecuador (Napo, Morona-Santiago, Zamora-Chinchipe) and northern Peru (Cajamarca, San Martín and Amazonas [Clements and Shany 2001, Brooks et al. 2009]). A recent record from Manu Biosphere Reserve was erroneous (H. Lloyd in litt. 2001). It is uncommon and local throughout its range, and may already be extinct (or nearly so) in Colombia (Juniper and Parr 1998), where recent surveys in apparently suitable habitat have failed to produce any records (P. G. W. Salaman in litt. 1999). In 1983, 5-25 were recorded daily at Jesús del Monte, San Martín (Davis 1986), but it has been recorded less frequently (C. Bushell in litt. 1999), or not at all, by subsequent observers at this site (Wege and Long 1995), suggesting a decline (C. Bushell in litt. 1999). However, it appears to occur naturally at low density (Juniper and Parr 1998), and may sometimes be overlooked and thus more widespread than records suggest.

Population [top]

Population:The population is estimated to number 1,000-2,499 individuals based on an assessment of known records, descriptions of abundance and range size. This is consistent with recorded population density estimates for congeners or close relatives with a similar body size, and the fact that only a proportion of the estimated Extent of Occurrence is likely to be occupied. This estimate is equivalent to 667-1,666 mature individuals, rounded here to 600-1,700 mature individuals.

Trend Justification:  This species is suspected to lose 39.4-39.9% of suitable habitat within its distribution over three generations (15 years) based on a model of Amazonian deforestation (Soares-Filho et al. 2006, Bird et al. 2011). Given the susceptibility of the species to hunting and/or trapping, it is therefore suspected to decline by ≥30% over three generations.
Current Population Trend:Decreasing
Additional data:
Number of mature individuals:600-1700Continuing decline of mature individuals:Yes
Extreme fluctuations:NoPopulation severely fragmented:No
No. of subpopulations:2-100Continuing decline in subpopulations:Unknown
Extreme fluctuations in subpopulations:NoAll individuals in one subpopulation:No

Habitat and Ecology [top]

Habitat and Ecology:It inhabits the upper tropical and lower subtropical zone, favouring tall, humid, montane forest at 1,050-1,700 m, but has occasionally been reported from savanna-like woodland as low as 500 m, and from stunted ridge-top forest up to 2,300 m. It is often seen in small flocks of 5-12, sometimes more (Juniper and Parr 1998), but occasionally in pairs (J. Hornbuckle in litt. 1999). It feeds on fruit, including Ficus spp., and reportedly raids maize crops (Juniper and Parr 1998).

Systems:Terrestrial
Continuing decline in area, extent and/or quality of habitat:Yes
Generation Length (years):5
Movement patterns:Not a Migrant

Threats [top]

Major Threat(s): Its fragmented habitats are affected by continuing deforestation (Snyder et al. 2000), especially in Colombia. Improvements to road networks lead to deforestation associated with human settlement of new areas. Habitat loss is also known to be occurring in the Cordillera de Cutucú and at Jesús del Monte.

Conservation Actions [top]

Conservation Actions: Conservation Actions Underway
CITES Appendix II. It has been recorded in Sumaco Protection Forest, Cordillera de Cutucú Protection Forest, Sangay National Park and Cayambe-Coca Ecological Reserve, Ecuador, with an old specimen collected in Serranía de la Macarena National Park.

Conservation Actions Proposed
Assess its distribution, population status and current threats through field surveys (Snyder et al. 2000). Maintain and improve the integrity of national parks in which the species occurs. Designate a protected area in the Cordillera del Cóndor, and involve local people in the land-use management of this region (Schulenberg and Awbrey 1997).
