Sao Paulo Tyrannulet Phylloscartes paulista

This species is classified as Near Threatened as it is suspected to be undergoing a moderately rapid population decline as a result of habitat losses. It was previously downlisted from Vulnerable as rates of habitat loss have slowed in some parts of its range, and its use of secondary habitats suggested that it may not be as threatened by the loss of mature forest as previously thought.

10.5 cm. Small, green-and-yellow tyrannulet. Pale greenish-olive above with lemon-yellow underparts. Lemon-yellow face with dusky loral spot. Narrow, pale yellowish supercilium wraps around rear of prominent, dark auricular crescent. Similar spp. Oustalet's Tyrannulet P. oustaleti is larger, has bolder face pattern, more horizontal posture, and cocked tail is constantly quivered. Voice Subtle but strident fuí-ri-ríp.

Distribution and population
Phylloscartes paulista occurs in south-east Brazil, east Paraguay and north-east Argentina. In Brazil, it is found in the Atlantic forests of Espírito Santo south to Santa Catarina (do Rosário 1996; Naka et al. 2011), and is considered fairly common in some protected areas, including the "Paranapiacaba fragment" (the 120,000 ha mosaic of Alto Ribeira, Intervales and Carlos Botelho state parks) and the Ilha do Cardoso (Ridgely and Tudor 1994) in São Paulo and Iguaçu in Paraná. In eastern Paraguay it has been recorded from Canindeyú south to Itapúa (Brooks et al. 1993, Hayes 1995, Lowen et al. 1996), but is uncommon. All Argentine records are from Misiones, where it is rare in Iguazú (Saibene et al. 1996). Due to its inconspicuous voice, its presence is likely to be overlooked, and it probably has a continuous distribution along the slopes of the Serra do Mar and Serra de Paranapicaba massifs at least between southern Rio de Janeiro (Parati) and Paraná.

Population justification
The global population probably numbers fewer than 10,000 individuals (del Hoyo et al. 2004). It is placed in the band 2,500-9,999 individuals, equating to 1,667-6,666 mature individuals, rounded here to 1,500-7,000 mature individuals.

Trend justification
A moderately rapid and on-going population decline is suspected owing to habitat loss.

It inhabits the middle storey of the lowland Atlantic forest interior, principally below 400 m, but locally up to 1,000 m (Clay et al. 1998; Naka et al. 2011), and will also use secondary forest.

Less than 20% of the original extent of this habitat remains intact (Brown and Brown 1992) owing to agricultural conversion and deforestation for coffee, banana and rubber plantations (Fearnside 1996). Remaining forest suffers from increasing urbanisation, agricultural expansion and associated road building (Dinerstein et al. 1995), but habitat destruction in the Brazilian range of the species has slowed significantly (although continuing in places), and the prospects of future losses are not as dire as in the last decades. Also, the species is known to use second growth, making it less vulnerable to the loss of mature forest.

Conservation Actions Underway
It is fairly common at Intervales State Park, Iguaçu National Park and Ilha do Cardoso State Park, Brazil. It is also present in Caaguazú, San Rafael and Ybycuí National Parks, Paraguay; and Iguazú National Park, Argentina, as well as several other (at least nominally) protected areas (del Hoyo et al. 2004). Conservation Actions Proposed
Effectively protect areas where the species occurs. Study its ecology and its ability to persist in degraded and fragmented habitats.
