This species is listed as Near Threatened, as it is uncommon and local within its range, and hence has a moderately small population which is likely to be declining owing to habitat loss, as well as the effects of bird trappers.

Geographic Range [top]

Range Description: Charitospiza eucosma occurs in north-east and central Brazil (central Piauí, south Maranhão and south-east Pará south through Goiás, west Bahia and central Minas Gerais to south-east Mato Grosso and central São Paulo) (Ridgely and Tudor 1989, Sick 1993), north-east Bolivia (Serranía de Huanchaca in Santa Cruz) (Killeen and Schulenberg 1998) and north-east Argentina (single records from Misiones in 1961 and, bizarrely, one recently collected in Tucumán [B. Schmidt and C. Milensky in litt. 1998]). It can be uncommon to fairly common, but has a very local and erratic occurrence (Ridgely and Tudor 1989).

Population [top]

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

Habitat and Ecology [top]

Habitat and Ecology: This species inhabits 'cerrado' and 'caatinga' habitats in lowlands (below 1,200 m). It has been observed invading recently burned areas (Ridgely and Tudor 1989, Bates et al. 1992), and may engage in local migrations or semi-nomadism in response to fire succession (Ridgely and Tudor 1989, Parker and Willis 1997).

Systems: Terrestrial

Threats [top]

Major Threat(s): Conversion to agriculture for Eucalyptus plantations, soybeans and pastures for exportable crops (encouraged by government land reform) has had a severe impact on its cerrado habitats in Brazil (Parker and Willis 1997). Caatinga habitats are less threatened, but still suffer from agricultural expansion and grazing. At least in Brazil, it is trapped for the cage-bird trade.

Conservation Actions [top]

Conservation Actions: Conservation Actions Underway
Conservation Actions Proposed
Conduct repeated surveys of sites throughout the known range to determine distribution, abundance, population trends and movements. Campaign for the protection of remaining cerrado habitats.
