This small forest bird has a large head with a small white spot above the bill and a short tail.  The male has a black head, glossy black upperparts and upper breast and white underparts, divided at the breast, a white wingbar and sides to the tail.  The female has a brown head and upperparts, grey brown chin and upper breast fading to white on the underparts.  The wingbar and sides of the tail are pale buff.  The male call is a short high pitched ‘swee’ and he sings with a warbling ‘ti oly oly oly oly oh’.  The female call is a reedy ‘seet’.

Tomtit eat mainly invertebrates (spiders, beetles, caterpillars, moths, weta, earthworms, flies, stick insects and wasps) supplemented with small fruits in autumn and winter.  A ‘watch and wait’ method is used – perching and scanning an area and then flying to catch the prey, usually on a nearby trunk or branch.  Insects are also gleaned from leaves and small branches. 

Pairs maintain their territory all year and stay together year after year.  Breeding is between September and January, during which up to 3 broods may be raised.  The female builds a bulky nest of twigs, bark, fibre and moss, bound with cobwebs and lined with tree-fern scales, moss and fine grasses.  The nest is in either a tree cavity, the end of a broken branch, in a fork attached to the trunk of a tree fern or in a thick  tangle of vines.  (In January 2004, tomtit nests in the Hunua pine forests were found in forked branches of gorse and at the top of decaying pampas grass.) The clutch of 3 – 6 cream coloured eggs with yellowish purple spots is incubated by the female for 15 – 17 days.  The chicks fledge at 17 – 20 days, and continue to be fed by both parents until the female starts renesting while the male takes full care of them until they are independent at c. 35 days old. 

To Maori the miromiro is one of Maui’s birds and is a significant bird, being esteemed with the huia, the royal albatross and white heron.  An observant person is spoken of as –“ he karu miromiro” - “having a tomtit eye” and the Maori called tomtits “scouts” or  “torotoro” due to their habit of appearing from nowhere in the forest.  He manu aroha te miromiro - “the miromiro is the lovebird” and it had a place in Maori rituals for birth, tohunga, and a new pa.

Occasionally vagrant male Tomtit are seen on Tiri but they disappear after a few days. 

The translocation of miromiro (North Island tomtit) to Tiritiri Matangi took place at the end of April 2004.  The birds were sourced from the Waytemore pine forests in the Hunuas, south east of Auckland city.
