Rufous Hornero are residents of second growth scrub and pastureland from central Brazil west to Bolivia and south to southern Argentina. Noted more for their distinctive nests than for their appearance, Rufous Hornero are large ovenbirds with rufescent brown upperparts, light rufous supercilia, and tawny breast and underparts. Rufous Hornero feed predominantly on insects such as beetles, crickets, ants, and termites, which they capture while foraging on the ground. Rufous Hornero are incredible architects that build domed nests out of mud and straw; these nests are 20 to 30 cm in diameter and 20 to 25 cm tall. The nests of the Rufous Hornero are almost never reused by the pair that built them, making these nests readily accessible to other birds and animals as nest locations and shelter.
