Assessment Information [top]

Red List Category & Criteria: Near Threatened ver 3.1
Year Published: 2012
Date Assessed: 2012-05-01
Assessor(s): BirdLife International
Reviewer(s): Butchart, S. & Symes, A.
Facilitator/Compiler(s): Butchart, S., Gilroy, J., O'Brien, A., Sharpe, C J
This species qualifies as Near Threatened as it has a moderately small population which is declining owing to continuing habitat destruction and degradation.

Previously published Red List assessments:
2008 Near Threatened (NT)
2004 Near Threatened (NT)
2000 Lower Risk/near threatened (LR/nt)
1994 Lower Risk/near threatened (LR/nt)
1988 Near Threatened (NT)

Geographic Range [top]

Range Description: Thraupis cyanoptera occurs in south-east Brazil (Espírito Santo and east Minas Gerais south to north Rio Grande do Sul, mostly on the coastal slopes of the Serra do Mar)  (Isler and Isler 1987, Ridgely and Tudor 1989, Parker et al. 1996). Reports from other localities almost certainly refer to Sayaca Tanager T. sayaca (Isler and Isler 1987, Bushell 1995). It is uncommon to fairly common, but local, within this range.

Population [top]

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

Trend Justification:  Slow to moderate population declines are likely to be occurring, owing to on-going habitat loss, although precise data on these trends are lacking.
Current Population Trend: Decreasing
Additional data:
Number of mature individuals: Unknown Continuing decline of mature individuals: Unknown
Extreme fluctuations: No Population severely fragmented: No
Continuing decline in subpopulations: Unknown
Extreme fluctuations in subpopulations: No All individuals in one subpopulation: No
No. of individuals in largest subpopulation: 100

Habitat and Ecology [top]

Habitat and Ecology: This species is found in the canopy and borders of montane and lowland evergreen forest and second growth at 200-1,200 m, occasionally to 1,600 m (Ridgely and Tudor 1989, Parker et al. 1996).

Systems: Terrestrial
Continuing decline in area, extent and/or quality of habitat: Unknown
Generation Length (years): 4
Movement patterns: Not a Migrant

Threats [top]

Major Threat(s): Agricultural conversion and deforestation for mining and plantation production are historic threats to its lowland forests (Fearnside 1996). Current key threats are urbanisation, industrialisation, agricultural expansion, colonisation and associated road-building (Dinerstein et al. 1995).

Conservation Actions [top]

Conservation Actions: Conservation Actions Underway
Conservation Actions Proposed
Repeat surveys of known sites to monitor population trends and patterns of habitat destruction. Conduct ecological studies to fully determine its habitat preferences and levels of tolerance of secondary habitats. Effectively protect significant areas of suitable forest at key sites.
