The Snowy Owl is a large owl covered almost entirely in white plumage — the only living owl known primarily for its white feathers, with even its toes feathered for insulation. Females grow noticeably larger than males, and with wings spread the bird can reach 140–165cm across. Though it may appear calm, it retains the sharp instincts and wariness typical of raptors, calling for experienced, knowledgeable care. Classified as Vulnerable (VU) by the IUCN, this striking bird deserves careful consideration of its needs before joining a household.

Snowy Owl key facts
- Care level
- Advanced
- Lifespan
- 15+ years
- Size
- 50-60cm (wingspan 140-165cm; males median about 1,658g with a range of 1,300-2,500g, females median about 2,102g with a range of 1,330-2,951g)
- Diet
- Frozen mice, rats, day-old chicks and quail; in the wild strongly dependent on tundra lemmings, taking a wider range including birds outside the breeding season
- Cage
- An Arctic bird that suffers badly in heat, so coping with the Japanese summer is the main challenge and cooling, on top of shade and ventilation, is effectively a prerequisite. It seldom perches in trees, so low platforms or rock-like structures suit it.
- Temperament
- Active by day, it perches in the open with a clear view. Nest defence in the breeding season is fierce, and the bird is strongly solitary.
- Vocalization
- In the breeding season the male gives a deep, loud hoot said to carry for kilometres, while outside that season it is largely silent.
- Notes
- The IUCN assesses it as Vulnerable. It is listed on CITES Appendix II, so import requires an export permit. It tolerates heat poorly, and Japanese summers bring a real risk of heat stress and aspergillosis, so temperature and hygiene must be managed closely.
