Ashy Prinia

The ashy prinia or ashy wren-warbler is a small warbler in the family Cisticolidae. This prinia is a resident breeder in the Indian subcontinent, ranging across most of India, Nepal, Bangladesh, eastern Pakistan, Bhutan, Sri Lanka and western Myanmar. It is a common bird in urban gardens and farmlands in many parts of India and its small size, distinctive colours and upright tail make it easy to identify. The northern populations have a rufous rump and back and have a distinct breeding and non-breeding plumage while other populations lack such variation.
