Here I describe for the first time nests of the Chestnut-tailed Antbird (Myrmeciza hemimelaena) in Bolivia. I found two nests in the understory of tropical lowland and hill tropical forests. The nests, 25 and 28 cm above ground, were basally supported open cups with a curved Geonoma sp. palm leaf as the structural foundation, woven with pieces of brown stringy rootlets, dead leaves, and leaf exoskeletons.
