Morepork
Ninox novaeseelandiae
The morepork is 26 to 29 cm (10 to 11.5 in) long, with the female slightly larger than the male. Females are slightly heavier at 170–216 g (6.0–7.6 oz) compared with the male's 140–156 g (4.9–5.5 oz). The morepork has generally dark brown head and upperparts, with pale brown spots on head and neck and white markings on the rest of the upperparts, with a pale yellow-white supercilium (eyebrow), dark brown ear coverts, and buff cheeks. The eyes are yellow to golden-yellow. The feathers of the chin and throat are buff with dark brown shafts. Voice: Moreporks have multiple distinct vocalisations. The "more-pork" call for which they are named is heard most frequently, but other vocalisations include a high pitched yelping call, a whistling call similar to kiwi, and a lower pitched "quork-quork" rumbling call. As many as 11 distinct calls have been observed by researchers.

Powerful Owl
Ninox strenua
The powerful owl has a long tail and a small head, giving it an atypical silhouette for an owl and imparting a more hawk-like appearance than any other large owl. The protruding bill and distinct brow ridges enhance the hawk-like appearance of the species. The facial disc is ill-defined. The upper parts are dark grey-brown, mottled, and barred with whitish. The underparts are white with bold, grey-brown, V-shaped barring. The tail has six narrow white bars contrasting with grey-brown. Voice: The male powerful owl's song is an impressive low, rather mournful-sounding and far-carrying double-hoot, whoo-hooo, each note lasting a few seconds at least, broken up by a brief silence and the second note being usually higher pitched than the first. The female has a similar call, but has a higher-pitched voice. Duets are frequently heard at the onset of breeding.
