Life History


Very little information. Presumably is mostly granivorous. Stomach contents of the type specimen of homochroa were "comminuted green vegetable matter" (Sclater 1858); of three specimens (duncani) were "plant material" (Willard et al. 1991); and the contents of another specimen (nominate homochroa) was "grit" (specimen data, Louisiana State University Museum of Natural Science). The nominate subspecies of the Andes is suspected to feed primarily on Chusquea bamboo (Fjeldså and Krabbe 1990).


Poorly known. Diet not well documented, nor is the foraging behavior. Typically forages in the understory or on the ground, near woody vegetation. Restless (Fjeldså and Krabbe 1990).
