The mourning wheatear is an omnivore and feeds on ants, beetles, grasshoppers, butterflies and other insects, as well as on plant material, including wild olives and red berries from juniper-like bushes (2).
The nest of the mourning wheatear is a flat cup made of dry grass, stems and roots, lined with rootlets, hair or wool. The nest is typically situated in the deep crevice of a rock, cliff or bank, or under a rock, and a small wall of stones is often placed at the entrance of the hole for protection (2).
The female mourning wheatear lays between three and six eggs, which are pale grey-blue and covered in reddish-brown and violet spots. The eggs are incubated for 13 to 14 days (2) by the female alone (5), and the chicks are able to leave the nest about 14 to 16 days after hatching. If the female produces a second brood, young males from the first brood may assist in finding food for the nestlings (2).
