Black Oriole

A small, slim endemic warbler common throughout New Zealand. Gray-brown above and paler gray to off-white below. Tail is darker, tipped with white, most noticeable in flight. Adults have a distinctive red eye. Juvenile similar, with yellow coloration and brown eyes. Male has a distinctive long, bubbling musical song. Female gives short “chirp” contact calls. More often heard than seen, this species forages for insects in the forest understory or scrub, sometimes hovering among the outer foliage and twigs. On mainland New Zealand, this is the only host species of the nest parasite Shining Bronze-Cuckoo, and so Gray Gerygone parents can be encountered feeding much larger cuckoo chicks. Despite inhabiting the same areas, distinguishable from Silvereye by slightly larger size, greener upperparts, and lack of a white eye-ring.

Bland, unremarkable-looking medium-sized babbler of open forest, forest edges, clearings, brushy riparian, and overgrown margins of cultivation in lowland and foothill areas. Extremely generic-looking, with no bright colors, a medium-length tail, and an average bill. Evenly-proportioned body gives it a rather bulbul-like outline. Note unmarked gray face, dark gray crown, dark rufous tail, and faint brownish wash on the chest. Especially similar to Moustached Babbler, but note present species’ darker crown, plain face (no moustache), and more slender bill. Scaly-crowned is also similar, but has a bright rufous patch on the forecrown. Plainly-colored Pellorneum babblers can be confusing, but note differences in proportions and profile. Most frequently-heard song is a beautiful but eerily human-like rising series of even whistles; when duetting, one bird often gives explosive “wik!” calls in response. Also gives a quicker, more cheery, and less human-like version of the song, as well as a short melancholy up-and-down series of whistles.

Rather plain sparrow-like bird. Sexes look alike: overall grayish brown and finely streaked with fairly plain head (narrow whitish eyering is indistinct). Note rather big bill, and fine dark breast streaks that sometimes merge into a dark blotch on the middle of the breast. A grassland species, found in open farmland, steppes, and heathlands. Mostly inconspicuous, but male sings from low perch on bush or fence, giving a unique if not tuneful song: harsh buzzing preceded by quiet knocking notes. Lacks white outer tail feathers shown by most buntings. Calls include various buzzes, as well as a quiet, clipped “tsi.”
