This species is considered Near Threatened, as it is thought to be experiencing a moderately rapid population decline owing to habitat loss and degradation, although it remains common in existing areas of suitable habitat.
|Previously published Red List assessments:|
|Range Description:||Sporophila melanogaster occurs in west Minas Gerais and south Goiás, south to Rio Grande do Sul, in south-east Brazil. It is locally common in suitable habitats.|
|Range Map:||Click here to open the map viewer and explore range.|
|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 declines are suspected to be occurring, owing to habitat loss and degradation, although data on trends are lacking.
|Current Population Trend:||Decreasing|
|Habitat and Ecology:||This species is found in grassland habitats at 700-1,100 m and lower altitudes in the non-breeding season (Ridgely and Tudor 1989, Parker et al. 1996). It is locally common in tall southern temperate grasslands, freshwater marshes and scrub, and is seasonally numerous (at least November-March) as a breeder in the highlands of Santa Catarina and north-east Rio Grande do Sul (Parker et al. 1996). Although apparently an austral migrant to the north of its range, its non-breeding range is poorly known (Ridgely and Tudor 1989, Parker et al. 1996).|
|Continuing decline in area, extent and/or quality of habitat:||Yes|
|Generation Length (years):||4.8|
|Movement patterns:||Full Migrant|
|Major Threat(s):||It is presumably threatened as a result of rapid destruction of its habitat by extensive cattle-ranching, agriculture, invasive grasses, wetland drainage and excessive pesticide use (da Silva 1995, Parker and Willis 1997).|
Conservation Actions Underway
Conservation Actions Proposed
Conduct surveys to determine the full extent of the range, particularly during the non-breeding season. Determine its ecological requirements and the extent of tolerance of agricultural habitats. Effectively protect significant areas of suitable grassland habitat at key sites.
