The ashy prinia or ashy wren-warbler (Prinia socialis) 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 farmland 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.
These 13–14 cm long warblers have short rounded wings and a longish graduated cream tail tipped with black subterminal spots. The tail is usually held upright and the strong legs are used for clambering about and hopping on the ground. They have a short black bill. The crown is grey and the underparts are rufous in most plumages. In breeding plumage, adults of the northern population are ash grey above, with a black crown and cheek with no supercilium and coppery brown wings. In non-breeding season, this population has a short and narrow white supercilium and the tail is longer. They are found singly or in pairs in shrubbery and will often visit the ground.
