LC
Upcher's Warbler Hippolais languida



Justification

Justification of Red List category
This species has an extremely large range and the population size is very large, hence does not approach threatened thresholds for the range or population size criteria. The population trend is not known, but the population 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 36,800-90,200 mature individuals, with 18,400-45,100 breeding pairs (BirdLife International 2021), and comprises approximately 15% of the species' global range, so a very preliminary estimate of the global population size is between 245,000-601,000 mature individuals, although further validation of this estimate is desirable. In Europe the trend for this species is not known (BirdLife International 2021). As no other data are available to derive trends, the global population trend for this species is unknown.

Ecology

This species favours trees and tall bushes in a variety of habitats: orchards, plantations, maquis on mountain slopes, scattered trees at desert edge, riverine forest in valleys. It is often associated with elevated ground, in mountains and on arid, rocky slopes with sufficient taller vegetation and nearness of water. Breeding occurs from April to July and clutches are three to five eggs. The nest is a strong, neat cup of grasses, plant stems and soft twigs, often covered with cobwebs, lined with fine fibres, plant down, fur and similar soft material and placed in fork of branch. It is thought to feed mainly on insects and other invertebrates. The species is migratory and winters in east Africa (Svensson 2006).

Threats

There are not thought to be any current significant threats to this species, at least within Europe.
