The chestnut-throated huet-huet (Pteroptochos castaneus) is a large passerine bird of the family Rhinocryptidae.

At an average mass of 165 grams (5.8 oz), it is, with the related black-throated huet-huet, the largest rhinocryptid and the third-heaviest tracheophone suboscine behind the giant and great antpittas.

[4] The species is found in temperate forest of Nothofagus species and Austrocedrus chilensis[5] on the humid fringe of the Mediterranean climate zone of Chile, chiefly in Biobío, Maule and parts of O'Higgins Regions, and also in a small adjacent area of Neuquén Province in Argentina.

[6] The Chestnut-Throated Huet-Huet feeds on insects and their larvae, and also a substantial number of seeds and fruit,[7] which it digs for in the forest floor with its long claws.

[8] Breeding occurs in spring between September and December, but the burrows ordinarily used to nest are dug during the winter rainy season when the soil is loosest.
