LC
Canary Islands Chiffchaff Phylloscopus canariensis

Justification
Although this species may have a restricted range, it is not believed to 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 very 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.

Taxonomic note
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). P. sindianus now includes P. lorenzii previously treated as distinct by Sibley and Monroe (1993).

Distribution and population
Phylloscopus canariensis is endemic to the Canary Islands, Spain. There have been no recent records of the Lanzarote subspecies exsul, which is likely to be extinct (del Hoyo et al. 2006).

Population justification
The breeding population, which is confined to Europe, is estimated to number 20,000-100,000 breeding pairs, equating to 60,000-300,000 individuals (BirdLife International 2004).

Trend justification
The population is suspected to be stable in the absence of evidence for any declines or substantial threats.
