This species has a small range which is severely fragmented and declining, and a small population which is declining as a result of habitat loss and trapping (Collar et al. 1992). It consequently qualifies as Vulnerable. There have been several local extinctions and many sites are highly threatened.
|Previously published Red List assessments:|
- 2013 – Vulnerable (VU)
- 2012 – Vulnerable (VU)
- 2008 – Vulnerable (VU)
- 2004 – Vulnerable (VU)
- 2000 – Endangered (EN)
- 1996 – Endangered (EN)
- 1994 – Endangered (EN)
- 1988 – Threatened (T)
|Population:||The population is estimated to number 2,500-9,999 mature 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 3,750-14,999 individuals in total, rounded here to 3,500-15,000 individuals.|
Trend Justification: A rapid and on-going population decline is suspected to be occurring, in line with rates of habitat loss and capture for the bird trade.
|Current Population Trend:||Decreasing|

|♦ No. of subpopulations:||2-100||♦ Continuing decline in subpopulations:||Yes|

Conservation Actions Underway
CITES Appendix II. Considered Vulnerable at the national level (Silveira and Straube 2008, MMA 2014), and protected under Brazilian law. It has been recorded in Dunas de Natal State Park (Silveira et al. 2003), Charles Darwin Ecological Refuge, Mata do Pau Ferro Ecological Park (Silveira et al. 2003), Serra dos Cavalos UFPE and Tapacurá Ecological Stations, and Saltinho and Pedra Talhada Biological Reserves. Significant areas are being reforested at Pedra Talhada, where protection is enforced by guards and apparently welcomed by local communities (A. Studer per A. Whittaker in litt. 1999). The recently decreed Murici Ecological Station is still ineffectively implemented and forest loss continues through pasture encroachment and charcoal production (Silveira et al. 2003). Captive birds have been confiscated and released into reserves, but this can only succeed if the protection of such areas is improved. Forestation schemes being undertaken to create new-forested areas along rivers and on steep slopes may have positive impacts owing to the ability of the species to utilise second-growth habitat (Silveira et al. 2003). Captive breeding populations exist (CoP 10 prop. 53).
Conservation Actions Proposed
Survey sites without recent records, especially São Miguel dos Campos, Tapacurá, Saltinho and João Pessoa, and any other remnant habitat fragments. Pursue conservation initiatives for the most important previously unreported populations, especially Usina Serra Grande, Mata da Macambira, Usina Utinga-Leao and Usina Santo Antonio (Silveira et al. 2003). Ensure the de facto protection of the Murici biological reserve. Enforce legal measures to prevent trade. Develop captive breeding programmes to support future reintroduction and population supplementation efforts.
