Annam Prinia Prinia rocki

A dull and poorly marked prinia with a strong bill and a long, graduated tail. Light brown above with faint dark streaking. Pale below, sometimes with some dark smudging along the sides of the breast. In breeding plumage, develops a rufous wash on the underparts. Found at moderate elevations in open dry forest, shrubby areas, and forest or agricultural edges. Can be retiring and difficult to see in dense vegetation. Sings two different song types: a dry rolling trill and a repeated two-syllabled “tulip.” Separated from other prinias by its plainness and lack of contrasting head markings.
