Rose-bellied Bunting Passerina rositae

Justification
This species is classed as Near Threatened because it has a small range, which may be in decline owing to habitat degradation and infrastructure development. Further research is required to assess the impact of these potential threats. If they are found to be serious, the species may qualify for a higher threat category.

Distribution and population
Passerina rositae has small range in south-east Oaxaca (Isthmus de Tehuantepec region west to the Chivela, Matías Romero and Juchitán areas) and extreme south-west Chiapas (La Trinidad), Mexico (Binford 1989, AOU 1998). It is locally fairly common to common in suitable habitat (Binford 1989).

Population justification
Partners in Flight estimated the population to number fewer than 50,000 individuals (A. Panjabi in litt. 2008), thus it is placed in the band 20,000-49,999 individuals here.

Trend justification
The population is suspected to be stable in the absence of evidence for any declines or substantial threats.

Ecology
This species inhabits swamp forest, denser portions of deciduous forest (Binford 1989), semi-humid deciduous gallery woodland and forest edge in hilly areas at 150-800 m (Howell and Webb 1995a).

Threats
The Pan-American Highway has fragmented habitat within this species's restricted range (Stattersfield et al. 1998). Many forests are now degraded or secondary, but whether this has had a significant impact on this species is unclear.

Conservation Actions Underway
No targeted conservation action is known for this species. Conservation Actions Proposed
Carry out surveys to assess the species's population size. Monitor population trends through regular surveys. Study the species's ecology, including habitat use. Investigate the impact of the Pan-American Highway and habitat degradation on the species. Effectively protect significant areas of suitable habitat at key sites, in both strictly protected areas and community led multiple use areas.
