Stitchbird, male - photographer: Peter CrawThe stitchbird used to be considered a member of the honeyeater family, along with tūī and bellbird, but is now placed in a family of its own. It shares some characteristics of the honeyeaters, however, such as a curved bill and a long tongue, frayed at the end like a brush, which is used to reach deep into flowers and drink nectar. Like the two New Zealand honeyeaters, stitchbirds feed on a mixture of nectar, fruit, and insects. At shared nectar sources, stitchbirds tend to be dominated by tūī and bellbirds, and may be forced to feed on lower-grade nectar. On Tiritiri Matangi the stitchbirds' diet is supplemented with sugar solution placed in feeding stations located in areas frequented by them. These are constructed so that tūī cannot enter, but bellbirds are small enough to take a large portion of this food.

The stitchbird is sexually dimorphic, the males being larger and more colourful than the females. The male has a velvety black head, upper breast and back, with white tufts behind the eyes, a bright yellow border across the breast and folded wings, and pale underparts. The white 'ear tufts' and tail are raised as part of the male's aggressive display, shown in the photo on the right. The female is a greyish brown with white wingbars.

Stitchbird, female - photographer: Peter CrawThe stitchbird naturally makes its nest in tree holes. On Tiritiri Matangi, specially designed nextboxes are provided, and nearly all the breeding stitchbirds use these. They have an unusual breeding habits, with two or more males and two or more females sometimes nesting together. 

The adult male has a loud explosive whistle 'see-si-ip', and both sexes give the familiar loud 'stitch' note. They also have a penetrating alarm call 'yeng-yeng-yeng', similar to the bellbird's but higher pitched, and a softer, more gentle, warbling song.

Stitchbirds have been extinct on the mainland since 1885, but have recently been re-introduced to a few protected mainland sites. Between 1885 and 1980 they survived only on Little Barrier Island/Hauturu, but have been translocated to a few islands.  They were first released on Tiritiri Matangi in 1995 and have bred successfully since then. They are closely monitored each year and are the subject of a long-running research programme.
