Araucaria Tit-spinetail Leptasthenura setaria
BirdLife is updating this factsheet for the 2016 Red List
Please email us with any relevant information

This species is considered Near Threatened, as it is suspected to be declining moderately rapidly owing to the loss of its highly specialised habitats through deforestation.

Taxonomic source(s)
SACC. 2006. A classification of the bird species of South America. Available at: #

Size: 17 cm. Summary: Small, slender and body patterned with a long tail. Id: head black streaked with white; with distinctive crest. Upperparts chestnut, duskier on wings and tail; underparts ochraceous, except whitish throat, speckled dusky. Similar: Could only be confused with the sympatric Striolated Tit-Spinetail L. striolata which has a streaked mantle and no crest. Hints: Active but sometimes hard to see, often first detected by its song and calls. Voice: The song is a high pitched descending trill, various high pitched call notes also given.

Distribution and population
Leptasthenura setaria inhabits southern temperate and secondary forests of south-east Brazil (south Rio de Janeiro to north Rio Grande do Sul) and north-east Argentina (Misiones).

Population justification
The global population size has not been quantified, but this species is described as 'common' (Stotz et al. (1996).

Trend justification
A slow to moderate population decline is suspected to be occurring, owing to the destruction of Araucaria woodlands. However, data are lacking on the magnitude of this decline.

This species occurs in temperate and secondary forests at 750-1,900 m (Ridgely and Tudor 1994, Parker et al. 1996). It is entirely dependent upon, and relatively common in, stands of Araucaria angustifolia, even occurring in commercially planted groves around buildings and in gardens (Ridgely and Tudor 1994, J. C. Chebez in litt. 1999). The overall population in commercial plantations in Argentina appears to be large (>7,000 birds), suggesting that such Araucaria plantations play an important role in the conservation of this species (Cabanne et al. 2007).

It is threatened by the destruction of Araucaria forest, which in the state of Paraná, Brazil, alone was reduced from an estimated original cover of 73,780 km2 to 15,932 km2 in 1965 as a result of clearance for pastureland and cultivation (Hueck 1978, Stattersfield et al. 1998). In Misiones, afforestation with Araucaria has resulted in the species colonising new areas, but there are fluctuations in area occupied, and Araucaria plantations are now regularly replaced with Pinus (J. C. Chebez in litt. 1999).

Conservation Actions Underway
Conservation Actions Proposed
Repeat surveys of known sites to determine rates of range contraction and population trends. Ensure that remaining tracts of Araucaria woodland receive adequate protection.
