The ash-throated antwren (Herpsilochmus parkeri) is a Vulnerable species of bird in subfamily Thamnophilinae of family Thamnophilidae, the "typical antbirds".

[3][4][5][6] The ash-throated antwren's specific epithet honors Theodore A. Parker III,[3] "the finest field birder/ornithologist that the world had ever seen".

Adult females have an orangish cinnamon forehead, a dark buff supercilium, and a black streak behind the eye.

Their chin, throat, and breast are ochraceous buff, their belly white, and their flanks and undertail coverts pale gray with a light buffy wash.

[8][3][9] The ash-throated antwren is known only from the watershed of the Río Mayo in the northern Peruvian Department of San Martín.

"Its small known range is coupled with widespread deforestation of the adjacent lowlands in the río Mayo valley.

Coca and coffee are widely cultivated in this region, and areas of suitable habitat are gradually being cleared for timber, agriculture, road developments and human population growth.
