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). The population trend appears to be increasing, 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:||Shirihai et al. (2001) estimated the population to exceed 10 million individuals, but in Europe, the breeding population is estimated to number 40,500,000-64,500,000 pairs, which equates to 81,000,000-129,000,000 mature individuals (BirdLife International 2015). Europe forms c.80% of the global range, so a very preliminary estimate of the global population size is 101,000,000-161,000,000 mature individuals, although further validation of this estimate is needed.|
Trend Justification: The population is suspected to be increasing owing to afforestation and land use changes leading to increased shrubby growth in parts of its range (del Hoyo et al. 2006). In Europe, trends between 1980 and 2013 show that populations have undergone a moderate increase (EBCC 2015).
|Current Population Trend:||Increasing|
|Habitat and Ecology:||This species breeds in almost any kind of forested area. It prefers broadleaf deciduous forest and mixed woodland, either mature or more open and with denser understorey. In addition it occupies riparian forest, parks and gardens with trees, fruit-tree plantations, orchards, and evergreen woodland. In the winter, it uses more with bushy areas rich in berries and other fruits, such as maquis and garrigue, olive groves, urban gardens and palm plantations. In Africa it is found in a large spectrum of habitats from lowland savanna rich in fruit trees to mangroves, riverside woodland and montane scrub and forest. Availability of fruit influences seasonal variation in habitat occupation. Breeding mainly occurs from mid-April to August and it lays two to seven eggs. The nest is a finely structured cup with rather thin walls and bottom, made of grasses and herbs and some twigs and rootlets and lined with finer grass, hair and roots. It is normally built low in broadleaf deciduous vegetation, especially in dense foliage of a shrub or bush or the branches of a small tree but also in tall herbaceous vegetation. The diet consists chiefly of insects in the breeding season and mainly fruit the rest of the year. On Atlantic and Mediterranean islands the species is sedentary, in the Mediterranean Basin and in parts of western Europe it is partially migratory and it is a long-distance migrant in northern and eastern parts of its range (Aymí et al. 2013).|
|Continuing decline in area, extent and/or quality of habitat:||Unknown|
|Generation Length (years):||4|
|Movement patterns:||Full Migrant|
|Major Threat(s):||In England, browsing deer (Cervidae) in young woodland can adversely alter habitat quality for understorey-dependent species such as this warbler (Holt et al. 2013). The species is trapped in some parts of its range.|
