Comportamiento

The ochre-flanked tapaculo forages in pairs on and near the ground in dense cover. Its primary prey is thought to be arthropods.<p>The ochre-flanked tapaculo is known to "double brood", laying eggs in September and again in November. The nest is a large ball of straw and grass with a side entrance that is usually placed 1 to 2 m (3.3 to 6.6 ft) above ground, though sometimes as high as 7 m (23 ft). Nests have been found in thick bushes, small trees, and piles of branches.<p>The ochre-flanked tapaculo's song is a short series of sharp "check" notes [1]. The members of a pair keep in contact with a softer "kek" call [2].
