Annam Limestone Babbler Gypsophila annamensis

A large, chunky, scraggly-looking babbler found in limestone hills covered with forest. Gray and brown overall with heavy streaking on the head, back, and throat. Forages close to the ground, often in and around rocky cracks and crevices. Song is a loud, ringing, rather hoarse-sounding sequence of whistled notes including some repeated phrases, sometimes given as a duet by a pair. Also gives harsh “grrr” calls. Similar to Streaked Wren-Babbler, but larger and longer-tailed, with bolder striping on the throat and no white spots on the shoulder.
