Justification
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). Despite the fact that the population trend appears to be decreasing, the decline is not believed to be sufficiently rapid to approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size has not been quantified, but it is not believed to 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

Population
The global population size has not been quantified, but the species is described as generally uncommon, although common in the Amur and Ussuri river valleys and common during its non-breeding season in South-East Asia and the Indian Subcontinent (del Hoyo et al. 2006). National population sizes have been estimated at < c.1,000 individuals on migration in Korea and c.100-10,000 breeding pairs and c.50-1,000 individuals on migration in Russia (Brazil 2009).

Thick-billed warbler

The thick-billed warbler (Iduna aedon) is an Old World warbler that breeds in temperate east Asia. It is migratory, wintering in tropical south east Asia. It is a very rare vagrant to western Europe.

This passerine bird is a species found in dense vegetation such as reeds, bushes and thick undergrowth. 5-6 eggs are laid in a nest in a low tree.

This is a large warbler, at 16–17.5 centimetres (6.3–6.9 in) long nearly as big as great reed warbler. The adult has an unstreaked brown back and buff underparts, with few obvious distinctive plumage features. The forehead is rounded, and the bill is short and pointed. The sexes are identical, as with most warblers, but young birds are richer buff below. Like most warblers, it is insectivorous, but will take other small prey items.

The song is fast and loud, and similar to marsh warbler, with much mimicry and typically acrocephaline whistles added.

It was sometimes placed in the monotypic genus Phragmaticola (or Phragamaticola) and for a long time as Acrocephalus and in 2009 found to belong to the Iduna clade.[2]
