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. Although the population size is unknown, it does not approach the thresholds for Vulnerable under the population size criterion. Although the species' population trend is known, it is not believed to be decreasing sufficiently rapidly to approach the thresholds 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 24,400-46,000 mature individuals, with 12,200-23,000 breeding pairs (BirdLife International 2021). However, Europe comprises only approximately 2% of the species' global range, so it is not considered advisable to extrapolate from this marginal population to produce a global population estimate. The European trend for this species is not known (BirdLife International 2021), although there some evidence that it may have increased in abundance in European Russia in recent decades (Keller et al. 2020). This species is considered to have a medium dependency on forest habitat, which is estimated to be declining at a rate of 7.8% over the past three generations within its mapped range (Global Forest Watch 2024). Based on these data, the global population trend is considered unknown.
Trend justification
.
This species breeds in the boreal and subarctic, principally along the northern limits of coniferous and deciduous forests, in valleys, often close to riverbanks in dense tangles of bushes and trees such as willow (Salix). It is also found in spruce (Picea) taiga, and on mountains to the tree-line in sparse spruce and birch (Betula) woodland. The breeding season is from June to August. The nest is a compact cup of twigs, moss, leaves and plant stems, lined with fine grasses and hairs and built in the fork of a low tree or in a thick shrub. It lays four to six eggs. The diet consists mostly of insects, on which the young are fed on as well. The species is migratory with the entire population wintering in central and eastern China and Korea (Hatchwell 2016).
As a northern breeding species it is likely vulnerable to the effects of climate change.
Conservation Actions Underway
Bern Convention Appendix II. There are currently no known conservation measures for this species within its European range.
Conservation Actions Proposed
Monitoring of this species should be implemented to detect any population changes.
