Morepork

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.
