The New Zealand fantail (''Rhipidura fuliginosa'') is a small insectivorous bird. A common fantail found in the South Island of New Zealand, also in the North Island as subspecies ''Rhipidura fuliginosa placabilis'', the Chatham Islands as ''Rhipidura fuliginosa penita'' and formerly (now extinct) the Lord Howe Island as ''Rhipidura fuliginosa cervina''. Also known as the pied fantail (pied morph only) or by its Maori name, Pīwakawaka or Tīwakawaka. The species is considered by many to be conspecific (the same) as the grey fantail of Australia and New Caledonia,〔(Bird Life International, Grey Fantail ), Grey Fantail entry on the Birdlife International Database including explanation as to why grey and New Zealand fantails are not considered to be separate species.〕 however due to differences in its calls some authorities now treat it as a separate species. ==Description==
This fantail is mid to dark grey or grey-brown above, yellowish/orange below, with a dark band across the chest below a white throat, white markings over the eye, and (depending on the race) either white-edged or entirely white outer tail feathers. It grows to in length, of which half is the tail, which, as the name implies, is often displayed fanned out. This reveals that the outer tail feathers that are light and the centre ones are dark. Some subspecies are found in a darker plumage, notably the "black fantail" morph seen in up to 25% of South Island birds and less than 1% of North Island birds (it is completely absent from the Chatham Islands).〔Boles, W.E. (2006). Family Rhipiduridae (fantails). Pp 200-244 in: del Hoyo, J., Elliott, A. & Christie, D.A. eds (2006) ''Handbook of the Birds of the World''. Vol. 11. Old World Flycatchers to Old World Warblers. Lynx Edicions, Barcelona. ISBN 978-84-96553-06-4〕 The black morph lacks the white areas and so is dark all over apart from a white spot behind the eye. Juveniles are similar to the adults but have a browner body and indistinct body markings.
