New Zealand fernbird

The New Zealand fernbird or simply fernbird is an insectivorous bird endemic to New Zealand. The Māori names are kōtātā or mātātā. It is a rich brown above and white below, with brown spots on both the throat and breast. Early settlers called it the "swamp sparrow" no doubt because of its colouration. The tail feathers are thin, dark brown, and spine-like. The birds reach a length of 18 cm - as measured from tip of beak to end of tail. However,almost half of that is tail

The New Zealand fernbird is a ground-dwelling bird, and is a reluctant flier, travelling mainly on foot or in occasional short flights of less than 15 metres. In the 19th century Buller described it as "one of our most common" but it has been adversely affected by the subsequent widespread destruction of its natural habitat following European settlement and is now rare

There are six fully protected sub-species of New Zealand fernbird:
*''M. p. punctatus''
*''M. p. vealeae''
*''M. p. stewartianus''
*''M. p. wilsoni''
*''M. p. caudatus''

''Megalurus rufescens'' is believed to have become extinct ''circa'' 1900.

The birds nest in sedges or other vegetation close to the ground, making a deep woven cup of dried rushes lined with feathers. Breeding occurs from September to February, producing clutches of 2-3 pinkish-white eggs with brown or purple speckles.
