Order: Passeriformes
Family: Pachycephalidae
Genus: Mohoua

Mohoua is a small genus of 3 species endemic to New Zealand. The Latin genus name is taken from either mohuahua or momohua - both Māori names for the Yellowhead.[1] All three species display some degree of sexual dimorphism in terms of size, with the males being the larger of the two sexes.[2] Mohoua are gregarious (more so outside the breeding season) and usually forage in groups . They also forage in mixed species flocks at times, frequently forming the nucleus of such flocks.[1] Unlike most species within Pachycephalidae, social organization and behaviour is well documented for all 3 Mohoua species; Cooperative breeding has been observed in all 3 species and is common in the Whitehead and Yellowhead.[1] The three species of this genus are the sole hosts for the Long-tailed Cuckoo which acts as a Brood parasite upon them, pushing their eggs out of the nest and laying a single one of its own in their place so that they take no part in incubation of their egg or in raising their young.[2]
