LC
Suiriri Flycatcher Suiriri suiriri



Justification

Justification of Red List Category
This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (extent of occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). Despite the fact that the population trend appears to be decreasing, the decline is not believed to be sufficiently rapid to approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.

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

Trend justification
The population is declining owing to widespread habitat conversion to pine and eucalyptus plantations and soy-bean and rice crops as well as habitat clearance for livestock farming (del Hoyo et al. 2004).

Distribution and population

This South American species is represented by three distinct forms occurring in parapatry: (1) Suiriri s. suiriri to the southwest in the Chaco/Pampas; (2) S. s. affinis located centrally in the Cerrado/southern Amazonia; and (3) S. s. bahiae to the northeast in the Caatinga.

Threats

The species is threatened by widespread habitat conversion to pine and eucalyptus plantations and soy-bean and rice crops as well as habitat clearance for livestock farming (del Hoyo et al. 2004).
