The white-winged apalis is an insectivore that is found in pairs, or sometimes in flocks with other bird species, searching for food in the forest canopy. It favours trees with thin, well-spread crowns, where it plucks its insect prey from leaves and twigs (2).
This species forms monogamous pairs that breed between October and January. Together the pair construct an oval bag-like nest made of beard lichen, lined with white and silky seed plumes, suspended from a bare branch many meters above the ground (2). The female lays and incubates a clutch of two to three eggs, and both the male and female feed beetle larvae to the newly hatched chicks (2).
