The Australian Boobook — sold in Japan under the name "New Zealand Boobook" — is instantly recognizable by its dark brown plumage flecked with white spots and its grey-green to yellow-green eyes. Despite the local trade name, its scientific name, Ninox boobook, identifies it as one of the smallest owl species native to mainland Australia. Reaching a total length of about 27 to 36 cm, it's a compact bird with a quiet, distinctly wild presence. As a nocturnal, largely solitary species, it calls for a keeper with some intermediate-level experience handling owls or other raptors.

Australian Boobook key facts
- Care level
- Intermediate
- Lifespan
- Little data
- Size
- 27-36 cm
- Diet
- Carnivorous: insects and small prey such as mice and chicks
- Temperament
- Mainly nocturnal but also active at dawn and dusk, roosting in secluded foliage by day.
- Cage
- It pounces from perches, so provide a room or aviary large enough to fly, with foliage or a box for daytime cover.
- Vocalization
- It calls a two-note 'boo-book', mostly at night.
- Feeding
- It eats insects and small vertebrates; combine insects with whole small prey and weigh the bird to set rations.
- Notes
- Sold as the New Zealand boobook, it is a different species from the morepork (N. novaeseelandiae) that name properly refers to, so check for Ninox boobook. Only foreign captive-bred birds are traded; wild birds in Japan, including native owls, may not in principle be caught or kept under the wildlife law.

7 things to know before welcoming a Australian Boobook
1Trade Name vs. Scientific Name
In Japan this owl is sold under the name "New Zealand Boobook," but its scientific name, Ninox boobook, actually refers to the Australian Boobook. It's worth knowing this naming quirk before you start researching the species.
2Distinctive Markings
Dark brown plumage dotted with white spots and grey-green to yellow-green eyes give this owl its unmistakable look. It's considered one of the smallest owl species native to mainland Australia.
3Adult Size to Expect
Adults typically reach a total length of about 27 to 36 cm. Plan your enclosure and perching space around this size from the start, with room to spare.
4Mainly Nocturnal
This owl is mainly nocturnal but is also active at dawn and dusk. It rests in inconspicuous spots in foliage by day, so provide dim, sheltered cover or a nest box for daytime rest and enough flying space for night-time activity.
5Solitary and Wary by Nature
These owls tend to prefer living alone and can be cautious around anyone unfamiliar. Give a new bird time to adjust at its own pace rather than pushing for close contact right away.
6Best Suited to Experienced Keepers
Reference data places this species at an intermediate difficulty level, suited to keepers with some background in owl or raptor care. If this is your first owl, it's worth learning from experienced keepers or reliable resources beforehand.
7Limited Lifespan Data
