Red List Category & Criteria: Near Threatened ver 3.1
Year Published: 2012
Date Assessed: 2012-05-01
Assessor(s): BirdLife International
Reviewer(s): Symes, A. & Butchart, S.

Justification:
Although this species is very poorly known, its population is believed to be moderately small and declining owing to habitat loss and degradation. Its small range is, however, not yet severely fragmented or restricted to few locations. For these reasons it has been classified as Near Threatened.

Geographic Range [top]

Range Description: Siphonorhis brewsteri is found in central and west Dominican Republic (particularly on the north slope of the Sierra de Baoruco and between Oviedo and Pedernales), Haiti (between Arcahaie and Montruis north of Port-au-Prince) and, at least formerly, was numerous on Ile de la Gonâve (Raffaele et al. 1998). It is thought to be generally rare, although it can be locally common and is possibly under-recorded (Cleere and Nurney 1998, Raffaele et al. 1998). Surveys at Las Cruces, Sierra de Bahoruco, in March 1996 revealed 4.5 birds/km2, essentially unchanged from 4.8 birds/km2 during 1976 surveys in the same area.

Population [top]

Population: This species is suspected to have a moderately small population based upon its apparent rarity and the limited availability of suitable habitat. It is placed in the band 10,000-19,999 individuals, equating to 6,667-13,333 mature individuals, rounded here to 6,000-15,000 mature individuals.
Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: It is found in arid or semi-arid lowlands, especially scrubby woodland, and also broadleaf, pine or mixed forest up to 800 m (Cleere and Nurney 1998). Perches inconspicuously by day on branches close to the ground. Crepuscular and nocturnal, calling at night.

Systems: Terrestrial

Threats [top]

Major Threat(s): Habitat destruction and introduced predators are thought to threaten the species (Raffaele et al. 1998).
