Taxonomic Notes: Phylloscopus collybita (Sibley and Monroe 1990, 1993) has been split into P. collybita, P. canariensis, P. ibericus and P. sindianus following AERC TAC (2003) (see Sangster et al. 2002).

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2012
Date Assessed: 2012-05-01
Assessor(s): BirdLife International
Reviewer(s): Butchart, S. & Symes, A.
Facilitator/Compiler(s): Ekstrom, J., Butchart, S.
This species has a very 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). The population trend appears to be stable, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size is extremely large, and hence does not 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 [top]

Population: In Europe (which covers >95% of the breeding range), the breeding population is estimated to be 360,000-530,000 breeding pairs, equating to 1,080,000-1,590,000 individuals (BirdLife International 2004).

Trend Justification:  The population is suspected to be stable in the absence of evidence for any declines or substantial threats.
Current Population Trend: Stable
