Gyrfalcon

Gyrfalcon key facts

Care level

Advanced

Lifespan

15-20 years

Size

Males 48-61cm and 805-1,350g with a wingspan of 110-130cm; females 51-65cm and 1,180-2,100g with a wingspan of 124-134cm

Diet

Frozen raptor food such as quail, day-old chicks, pigeon and rats; in the wild birds and mammals, birds more often taken on the ground than in the air

Cage

As the largest falcon it needs a spacious weather-proof, predator-proof mews or tethered housing plus daily free flight. Being an Arctic bird it suffers in heat, so provide shade, ventilation and summer cooling.

Temperament

A solitary hunter with no group sociability. Large and powerful, it has been prized in falconry for centuries, but handling demands real experience and sustained weight management.

Vocalization

When excited or defending a nest it repeats a harsh low call. It is not a persistent caller, but the volume matches its size.

Notes

CITES Appendix I. It is a designated internationally endangered species in Japan, so transfer or sale requires a registration certificate; only captive-bred birds are traded, so always check the certificate and provenance. It tolerates heat poorly and Japanese summers bring a real risk of aspergillosis, so temperature and hygiene must be managed closely.

About Gyrfalcon

A guide to the Gyrfalcon, the largest falcon species — its striking white plumage, Arctic origins, temperament, size differences, and what advanced keepers should know before bringing one home.

7 things to know before welcoming a Gyrfalcon

1. 1An Advanced-Level Raptor

   The Gyrfalcon is considered a difficult species to keep well. Handling one calls for specialized raptor knowledge and hands-on experience. First-time keepers should study thoroughly and prepare well in advance.

2. 2Marked Size Difference by Sex

   Males measure roughly 48–61 cm and weigh 805–1,350 g, while females are noticeably larger at 51–65 cm and 1,180–2,100 g. Wingspan reaches 110–130 cm in males and 124–134 cm in females, so the space you'll need depends on the sex of the bird you bring home.

3. 3Room to Fly

   With a wingspan exceeding a meter, this large raptor needs daily space to stretch its wings and equipment that allows safe flight. A cramped setup puts unnecessary strain on the bird.

4. 4A Bold, Independent Temperament

   True to its raptor nature, the Gyrfalcon is sharp and fiercely independent — it won't bond the way a dog or cat does. Building trust takes patience and consistent handling.

5. 5Color Varies by Individual

   Alongside the all-white pale morph, individuals with grayer plumage also exist. The pure white form that gave the species its Japanese name is just one of several color variations.

6. 6Active Year-Round by Nature

   Gyrfalcons breed in Arctic tundra and forest and migrate to more open habitat in winter, which keeps them active regardless of season. Owners need an environment that supports that activity level.

7. 7Preparing Before You Bring One Home

   Talk with an experienced raptor keeper beforehand and form a concrete picture of the daily care and housing involved. Approach the decision with a genuine, long-term commitment in mind.
