''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.〔''"Handbook of Australian, New Zealand and Antarctic Birds"; Volume 7'', edited by Peter Higgins, OUP, 2000〕 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.〔Zachary Aidala et al. Phylogenetic relationships of the genus Mohoua, endemic hosts of New Zealand’s obligate brood parasitic Long-tailed Cuckoo (''Eudynamys taitensis''). Journal of Ornithology, published online June, 2013; doi: 10.1007/s10336-013-0978-8〕 All three species display some degree of sexual dimorphism in terms of size, with the males being the larger of the two sexes.〔Barrie Heather and Hugh Robertson, ''"The Field Guide to the Birds of New Zealand" (revised edition)'', Viking, 2005〕 ''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.〔 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.〔 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.〔 == Species == *Whitehead, ''Mohoua albicilla'' - (Lesson, 1830) *Pipipi, or Brown Creeper, ''Mohoua novaeseelandiae'' - (Gmelin, 1789) *Yellowhead, ''Mohoua ochrocephala'' - (Gmelin, 1789) 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Mohoua」の詳細全文を読む スポンサード リンク
