Mohoua is a small genus of three bird species endemic to New Zealand. The scientific name is taken from either mohuahua or momohua - both Māori names for the Yellowhead.[1] Their taxonomic placement has presented problems: They have typically been placed in the Pachycephalidae family (whistlers), but in 2013 it was established that they are best placed in their own family, Mohouidae.[2]

All three species display some degree of sexual dimorphism in terms of size, with the males being the larger of the two sexes.[3] 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] Social organization and behaviour is well documented for all three Mohoua species; cooperative breeding has been observed in all three 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 eggs or in raising their young.[3]
