[edit] Distribution

The known breeding range extends from the Hamalayas east to Myanmar, northern Thailand and China; south of this range, sporadic occurances in India, Sri Lanka, South-east Asia, the Malay Peninsula and Sumatra fall mainly during the wintering periods and are therefore assumed to be either non-breeding visitors or vagrants due to the lack of evidence of breeding within this range.
