Assessment Information [top]

Red List Category & Criteria: Vulnerable B1ab(i,ii,iii,v);C2a(i) ver 3.1
Year Published: 2012
Date Assessed: 2012-05-01

This species is confined to a relatively narrow coastal strip where it is currently known from just ten locations. Its range is thus small and fragmented, and even protected areas are under threat, and it therefore qualifies as Vulnerable.

Geographic Range [top]

Range Description: Herpsilochmus pileatus is known from 10 localities along the coast of southern Bahia, Brazil (Whitney et al. 2000). It occurs from Baía de Todos Santos near Salvador in the north to the Trancoso area in the south (Whitney et al. 2000). It is apparently common/abundant in suitable habitat.

Population [top]

Population: Population estimate = 2.6-9.6 individuals/km2 x 270 km2 (45% EOO) = 702-2,592, i.e. probably best placed in the band 1,000-2,499 as described as common in suitable habitat (density range from estimates for two congeners in the BirdLife Population Densities Spreadsheet).

Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: This species occupies forests, forest fragments, second growth, cabrucas and restinga vegetation. Forages by gleaning invertebrates from vegetation in the mid-storey and canopy. Sometimes sallies and hover-gleans (del Hoyo et al. 2003).

Systems: Terrestrial

Threats [top]

Major Threat(s): Coastal forests in southern Bahia have suffered tremendous reduction in size during the last few decades. Logging companies, pastures, and social pressure from native peoples and landless people movements are some of the factors that have contributed to the deforestation process. The species has a very limited range, and although common, remaining vegetation is still being destroyed. Planned large-scale tourist resort development along the coast of southern Bahia may also have a large negative impact (del Hoyo et al. 2003). Designated protected areas where the species could be safe are under threat themselves (J. F. Pacheco in litt. 2001).

Conservation Actions [top]

Conservation Actions: Conservation Actions Underway
Few protected areas exist for this species but Una Biological Reserve, Monte Pascoal National Park and the Porto Seguro/Florestas Rio Doce SA Forest are important (del Hoyo et al. 2003).

Conservation Actions Proposed
Secure the adequate protection of a number of sites for this species.
