Hill Prinia

The hill prinia is a passerine of the family Cisticolidae found in China, India, Indonesia, Laos, Malaysia, Myanmar, Thailand and Vietnam. It was formerly considered conspecific with the black-throated prinia (Wikipedia, general species account).

That short account is the only source read for the Bhutan guide. It does not name Bhutan, so the species' occurrence there is flagged for checking, and it gives no plumage, size, habitat, diet or breeding information.
