Yellowhammer, male - photographer Dr Kerry RodgersIntroduced into New Zealand between 1862 and the early 1870s and now found throughout the country in farmlands, orchards and open tussockland.

As the name suggests, the adult male has a bright yellow head; underparts are also yellow, there is brownish streaking on the sides of the face and on the crown, the breast has a cinnamon wash and the flanks are pale yellow. The adult female is duller with a more streaky appearance. Both have reddish-brown, dark-streaked upperparts, rufous rump and white outer tail feathers. The call is a ringing metallic ‘tink’ or ‘twick’; the male song is ‘chitty-chitty-chitty…sweee’ often characterised as ‘a little bit of bread and no cheeeeese’.

Yellowhammers eat a mix of seeds from introduced weeds, grasses, clover and cereals and invertebrates such as caterpillars, beetles, flies, bugs and spiders.

They form flocks in autumn and winter but are territorial during the breeding season from October to March. The nest is a cup of dry grass, lined with rootlets, moss, hair, wool and feathers. It is usually built on or very close to the ground in gorse, brambles, bracken, long grass, etc. The clutch of 3–5 whitish-pink eggs with dark brown scribbling lines is incubated mainly by the female for 12–14 days. Both parents feed the chicks which fledge at 12–13 days.

Yellowhammers are not very common on Tiritiri Matangi, but are often seen in the scrubby and more open areas around the edges of the bush.
