Brown Tanager Orchesticus abeillei



Justification

Justification of Red List category
This scarce species is listed as Near Threatened as it is suspected to be declining moderately rapidly across its range owing to habitat loss.

Population justification
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 likely to be occurring, owing to on-going habitat loss throughout the range.

Distribution and population

Orchesticus abeillei is uncommon to fairly common in south-east Brazil (south Bahia to north Santa Catarina, with an isolated population in central Minas Gerais) (Ridgely and Tudor 1989, Parker et al. 1996, do Rosário 1996). Birds apparently migrate from Espírito Santo and Rio de Janeiro to south Bahia in the austral winter (Isler and Isler 1987).

Ecology

This species occurs at 750-1,600 m in the middle and upper strata of montane evergreen forest and its borders.

Threats

Its montane forests have suffered less destruction than adjacent lowland areas, but isolated patches in the north of its range, particularly within its Bahia wintering grounds, have virtually disappeared owing to the expansion of pasture and cultivation, and those remaining are under pressure from clearance and fires spreading from cultivated areas (Gonzaga et al. 1995, Stattersfield et al. 1998).

Conservation actions

Conservation Actions Underway
Conservation Actions Proposed
Conduct surveys throughout the range to determine its current distribution and abundance, as well as understand seasonal movements. Monitor populations at known sites in order to determine population trends. Conduct ecological studies to identify precise habitat requirement and responses to habitat degradation or fragmentation. Protect significant areas of suitable forest at key sites.
