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. |

| Range Description: | This species predominantly breeds across Siberia and the Himalayas, and winters in the northern Indian Subcontinent, northern south-east Asia, southern China, and southern Japan, but there are also some resident subspecies, including neilgherriensis in the hills of south-west India, and horsfieldi from Java to Sumbawa, Indonesia. Subspecies major was previously considered specifically distinct and Critically Endangered, with only c.58 breeding birds estimated to remain in 1996. It is confined to the islands of Amami-ooshima and Kakeroma-jima in the northern Nansei Shoto Islands, Japan. |

| Population: | The global population size has not been quantified. The species is variously described as "uncommon" to "fairly common" across much of its range (Clement and Hathway 2000), In Europe, the breeding population is estimated to number 25000-100000 breeding pairs, equating to 75000-300000 individuals (BirdLife International 2004), but Europe forms <5% of the global range. |
| Habitat and Ecology: | The taxonomy of the species has been in flux, and much more research and analysis is needed on variations in song and measurements to resolve this situation (Collar 2004). |
| Systems: | Terrestrial |
| Major Threat(s): | Subspecies major is threatened by deforestation and invasive alien predators (BirdLife International 2000, Clement and Hathway 2000). |
