Habits Viduine finches are avian brood parasites and require specific species of finches to raise their offspring. Whydahs do not build their own nests, but rather deposit their eggs in the nests of other species which act as hosts. The host species then raises the whydah chicks alongside their own. Male whydahs control territories where the host birds are breeding; they sing a song that mimics that of the host species to attract hens. Whydahs do not form monogamous pairs; rather, a male whydah will breed with numerous females, and a female whydah will go on to breed with numerous males in order to spread her eggs over multiple territories.

A single female whydah is estimated to lay around 22 eggs in a breeding season. Parasite-host relationships for the paradise whydahs are as follows: Northern Paradise Whydah V. Host eggs are not removed nor destroyed by the whydah, nor are the host chicks ejected from the nest by the whydah chicks. In fact, fledging success data suggests that the whydah's parasitism does little damage to the host's productivity. Although it is generally believed that baby whydahs have mouth marking patterns, begging calls, and begging postures which "exactly" mimic the host species' in order to avoid detection as well as to enable the chicks to effectively compete while begging, some differences are noted in the field.

Palate characteristics of the host and parasite also differ in the Togo Paradise Whydah: the blue-violet signal markings of the mouth are larger and more elongated in the host than parasite. L' emb.
