Data Zone
Justification of Red List category
This species has a very large range and the population size is extremely large, hence does not approach threatened thresholds for the range or population size criteria. The population trend appears to be stable, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion. For these reasons the species is evaluated as Least Concern.
Population justification
In Europe, the total population size is estimated at 924,000-1,540,000 mature individuals, with 462,000-768,000 breeding pairs (BirdLife International 2021), and comprises approximately 75% of the species' global range, so a very preliminary estimate of the global population size is between 1,230,000-2,050,000 mature individuals, although further validation of this estimate is desirable. The species' population in Europe is considered to have remained relatively stable over three generations (10 years) (BirdLife International 2021). As this region holds the vast majority of the species' global range, the global population size is considered to be stable over three generations.
Trend justification
.
In the breeding season this species is normally found in hilly areas in Mediterranean scrub with kermes oak (Quercus coccifera) and Portuguese oak (Quercus faginea), and in open forest of mixed oaks and sweet chestnut (Castanea sativa) with a well-developed layer of cistus scrub. Above the tree-line, it is found in mixed scrub and open heath and may also breed at lower levels in riverine woodland with willow (Salix). Egg-laying occurs from mid-April to the end of May and it normally lays four to five eggs. Little is known about its breeding and foraging habitats but they are most likely similar to Phylloscopus collybita. The species is migratory, with the majority of birds probably wintering in tropical West Africa (Clement 2015).
There are not thought to be any current significant threats to this species.
