Owls and eagle owls and other raptors have recently become increasingly popular as pets due to their mysterious appearance and unique ecology. However, raising raptors requires specialized knowledge that differs significantly from general bird care. In particular, feeding management is key to maintaining health, and understanding the right type of food, feeding methods, and management of castings (regurgitations) is essential. This article provides practical explanations of feeding management and health maintenance for raptors.
Basic Diet of Owls and Eagle Owls
Wild owls and eagle owls are strictly carnivorous, hunting whole small mammals (mice, moles, etc.), small birds, insects, and fish. A defining characteristic is that they regurgitate indigestible bones, feathers, and fur as "pellets (castings)."
Basic feeding in captivity:
- Frozen mice and frozen rats as staple food (most nutritionally balanced)
- Live prey (live crickets, chicks) require caution due to parasite risks
- Avian foods (quail, chicks) can be used for dietary variety
- Supplements are generally unnecessary if frozen mice are the staple diet
Types of Frozen Mice and Thawing Methods
Frozen mice are the basic food for owl care. They range in size from pink mice (newborns) to adult mice and rats. Choose the appropriate size based on the raptor species and size being fed.

Proper Thawing Method
Recommended: Thaw slowly in the refrigerator over 12-24 hours. Warm to body temperature (approximately 38°C) before feeding to increase feeding response.
Methods to avoid: Microwave thawing (interior does not warm uniformly and can cause bacterial growth and nutrient loss)
Use on the same day after thawing, and avoid refreezing any leftovers.
Feeding Frequency and Quantity Guidelines
Feeding frequency varies by species, size, season, and individual condition. General guidelines are as follows:
Small species (Scops Owls, Spotted Eagle-Owls, etc.): 1-2 pink or fuzzy mice daily
Medium species (Barn Owls, Martial Eagle-Owls, etc.): 2-3 adult mice every other day
Large species (Blakiston's Eagle-Owls, etc.): 1-2 rats every other day
During breeding season, molting period, and growth stage, more energy is needed than usual. Conversely, reduce amounts during periods of low activity or after illness recovery.
Importance of weight management: Even slight weight changes in raptors serve as a health indicator. Make it a habit to weigh weekly (in grams), and consult a veterinarian if you notice sudden changes.
Management of Pellets (Castings)
Pellets are regurgitated bundles of indigestible bones, fur, and feathers from an owl's meal. Pellets are evidence of healthy digestion and are typically regurgitated within 12-16 hours after feeding.
Characteristics of normal pellets:
- Elongated oval shape
- Fur and bones are compacted
- Little to no odor
Signs of abnormality:
- No pellets for 48+ hours (possible indigestion or intestinal blockage)
- Undigested food present (excessive feeding or digestive issues)
- Pellets covered in mucus
Water Provision and Hydration
Frozen mice contain sufficient water, so hydration is primarily met through food. However, clean drinking water should always be available. Place fresh water daily in a shallow, stable container.
Some species enjoy bathing, so providing shallow water trays for bathing during warm seasons provides behavioral enrichment.
Common Health Issues and Prevention
Aspergillosis (Fungal Infection)
This fungal infection results from high humidity, old food, or unsanitary cage conditions. Prevention requires proper ventilation, clean cage management, and providing fresh food.
Vitamin D Deficiency and Metabolic Bone Disease
Insufficient sunlight (or UVB lighting) impairs calcium metabolism and weakens bones. UVB lighting installation is recommended for indoor-kept birds.
Overgrowth of Beak and Talons
Providing appropriately hard food (such as whole mice with bones) allows natural wear. If overgrowth occurs, consult a veterinarian or experienced falconer for trimming.
Parasites
External parasites (mites, lice) and internal parasites (roundworms, etc.) can be problematic. Perform regular fecal checks and deworming as needed.
Importance of Regular Health Checkups
Raptors have a strong instinct to hide signs of illness, and by the time they appear visibly ill, the condition has often already progressed significantly. Strongly recommend annual to biannual checkups (blood work, fecal tests, weight measurement) with an avian or exotic animal specialist veterinarian.
Important Checks When Acquiring a Raptor from a Breeder
At br-choku, you can acquire owls and eagle owls directly from avian specialists. When purchasing, confirm the following:
Species name, origin, hatch date (pedigree information)
Hand-reared or parent-reared (confirm hand-taming level)
Current feeding type and frequency
Vaccination, quarantine, and parasite testing records
Confirmation that the individual is legally compliant with the Washington Convention (CITES)
Conclusion
Proper feeding management centered on frozen mice and observation of pellets form the foundation of maintaining owl and eagle owl health. Make regular weight measurements a habit and develop the practice of detecting abnormalities early. With collaboration from specialist veterinarians and careful attention to individual information from the breeder, enjoy a rich life with raptors for years to come.
