Tyto Alba Order: Strigiformes Family: Tytonidae
Although often readily available through wildlife rehabilitation sources, barn owls are not a beginner owl, and acquisition of one should only be considered if facility has experienced handlers. Many facilities have noted they are more challenging than other owl species due to their naturally secretive nature. For use in programming, it is best to consider a hand-reared individual, although even then, experience working with owls and a strong foundation in training utilizing positive reinforcement is necessary for handlers working with this species.
To maximize lifelong welfare of an owl that is going to participate in ambassador animal programs, and as such be exposed to close contact with humans and a variety of stimuli that could otherwise be intimidating or inducive of unavoidable stress, it is recommended to hand-rear individuals slated to become ambassadors. Hand-rearing should occur during the formative stage of life, within the first few months of hatching. Hand-rearing owls allows the human caretaker to expose the owl from an early age to a variety of conditions it may encounter as an ambassador (crowds, vehicles, buildings, novel noises, etc.) while it is at the best stage to learn these stimuli are non-threatening, which generally helps them adapt to life under human care, in their roles as ambassadors, much more than parent-reared owls.
Natural History Information
Range and Habitat
Barn owls are found throughout the world, and have one of the most widespread ranges of any bird species. They can be found in many different habitats, but prefer open spaces for hunting such as fields and grasslands. They nest in tree cavities, buildings (barns), on rooftops, and will even nest on the ground.
In the wild, it is unusual to find a barn owl over the age of five. However, in human care, they do well and can live into their twenties and beyond. The oldest recorded barn owl was 34 years.
Owls that feed in agricultural areas provide benefits to humans by killing large numbers of small rodents which might otherwise eat crops in the field or in storage.
Life Cycle Natural History Relevant Information
- During the breeding season, both male and female individuals may demonstrate natural breeding behaviors that make them more challenging to work with and around. Consider time off from ambassador duties during this time.
Temperature, Humidity, Light Cycles
- Barn owls are found world wide in a variety of climates. Typically, for healthy birds, no special temperature modification is necessary.
- This species can be successfully managed on a variety of substrates, such as pea-gravel, sand, dirt, grass.
Social Housing/Colony Management
- Although more typically housed solitary in ambassador situations, it is possible to house more than one barn owl together. In such cases attention should be paid to individual preference and birds should be afforded enclosure space large enough to be separate from each other, should they choose.
Other General Housing Requirements or Management information
- Multiple perching options are necessary to maintain good foot health.
- Having a perching area which is high and also in the corner gives the bird a sense of security and mimics natural behavior of perching on a branch near a tree trunk. It is also important to have both sun and shade areas in the exhibit, as well as an area which is covered so the bird can remove itself from the elements if need be.
- Most owls do well with some kind of box or small shelter in their enclosure.
- Space should meet minimum USFW standards.
- Enclosure be constructed with materials that reduce the possibility of damage to the feathers or to the owl itself (for example, bare wire mesh is less desirable than vertical bars or coated mesh).
- Flight-capable individuals need flight exercise to maintain muscle mass.
- A double door mew entrance is ideal for any bird of prey. This allows handlers to enter the enclosure safely and without incident.
Diet in the Wild
- Majority of their diet is made up of small rodents such as mice and voles, but also eat other small mammals as well as occasional passerines.
Diet under human care
- Mice, rats, chicks, quail, rabbit.
- Preferences can vary by individual, but, in general, barn owls show preference for mice over most other meat types.
Enrichment & Training
Behavioral Relevant Information
- Raptors seize and rip apart their prey. Offering whole prey items, shreddable enrichment items, items they can grab and manipulate with their talons or shred with their beaks are all good forms of enrichment.
- Changing perches within their habitat.
- Addition of browse.
- The most successful enrichment devices appear to be items that can be footed and shredded, such as paper products, cardboard boxes, lettuce, melons, squash or other produce. These items can be provided alone or stuffed with prey or diet, although raptors should be monitored for ingestion of foreign objects if food is delivered with a novel item. Other successful items include tennis balls, holl-ee rollers, and canvas dog toys, which present opportunities for seizing, grabbing, mock “killing,” and mantling.
- Daily enrichment is recommended.
Other Enrichment Resources
- AZA’s Raptor TAG has a comprehensive list of raptor-appropriate enrichment as well as other suggestions on raptor enrichment programs on their website.
- Voluntary step-up to glove
- Voluntary loading into crate
- Voluntary scale
- Voluntary nail trim
- A-B flights
- Calm behavior on glove
Reinforcers used & schedule of reinforcement
- Using food and/or weight management as part of a good behavioral management program facilitates training by creating a learning environment in which owls want to participate. Training strategies that involve reducing food offered to the point of compromising the health of the bird are considered unacceptable. Food management and weight management practices that are safe for the owl and trainers, provide for the health and welfare of the owl, and facilitate training are recommended.
- Food and or weight management should be done with an understanding of the process and considerations. The decision to use weight management should not be taken lightly nor undertaken at all by staff who do not have a comprehensive understanding of managing weight and diet.
Colony or Breeding Management
- Notes species is housed or managed socially or for breeding purposes.
- Dimorphism or practiced ways to individually mark species (such as those in colonies, like giant millipedes).
Wild owl populations face a multitude of threats; fortunately, there are a number of individual and community-level actions that people can take to help to protect owls in the wild. Some examples are listed below.
Pesticide and Rodenticide use:
As predators of rodents, all raptors, including owls, are incredibly vulnerable to rodenticide poisoning. Encourage responsibly use and properly manage rodenticides. Owls are also susceptible to pesticide biomagnification and mercury poisoning. Encourage people to avoid using pesticides on their lawns, and instead rely on native plantings or other environmentally responsible methods of pest management.
Roadside litter is a threat to many owl species. Rodents are attracted to the litter, and a low-flying owl in pursuit of a rodent is vulnerable to a vehicular collision. Encourage visitors to dispose of their trash in an appropriate receptacle, not on the roadside, even if it is biodegradable. Owls are also susceptible to death through barbed wire or electrocution from power lines. We can help by supporting man-made barriers that keep birds away from high-electricity areas. Owls are highly sensitive nesters, and even slight disturbances can lead to abandonment. We can help by reducing activity in known nesting areas and avoiding owl nests when trimming trees or in forestry management.
Protecting habitat and supporting conservation organizations can help to protect populations of both predator and prey species.
Threats and Conservation Status
IUCN Conservation Status: Least Concern, is protected at the state level in some states.
Prejudices against birds of prey still persist among many who wrongly believe that they harm wildlife or present major threats to domestic animals. Biological studies have documented their ecological importance as major controls on rodent populations. Some birds of prey feed on snakes, insects or other potential pests. No species of raptor poses a significant threat to domestic animals.
Instruct guests to never litter, especially when they are in a car. Throwing trash out along the roads not only makes the roads less attractive, but can also attract animals to the sides of the road. Some of these animals might look appetizing to an owl, hawk, or other predator which are then more likely to be hit by passing vehicles.
Interesting Natural History Information
Did you know…
- Barn owls have asymmetrical ears? The owl’s facial disk helps to funnel sound into the owl’s ears – allowing them to pinpoint sounds not only on a horizontal, but also vertical plane. The left ear is positioned higher than the right, but points downward. The right ear points upward. This “super” hearing gives the Barn owl the ability to hunt in complete darkness!
Handling & Presentation Tips
- When hand-rearing Barn owl chicks to become program animals, it is strongly encouraged to start feeding them exclusively on the glove as soon as they can stand. This builds a strong association with the gloved hand at an early age and positive reinforcement for standing on it.
- Barn owls tend to prefer small, enclosed spaces, so although some can make good presentation animals, many individuals may not be comfortable around large groups and in open space without a lot of training.
- This species may be presented on glove, on perch, or in free-flight demonstrations. For tethered presentation, whether that is to the glove or to a perch, attention should be paid to avoid bating. Bating is not something that should be accepted from owls, if there are instances of such, it is an indication of discomfort, with the handler or the situation, and that discomfort should be addressed, not ignored.
Pubic Contact and Interaction Guidelines
- Public contact with this species is not advisable.
- Touching is not advisable.
- Transport box suggestions Raptor Rig and Varikennel.
- A couple things to keep in mind, crates should not be carried by the handle, but rather using two hands on either side of the crate and supporting it adequately. Swinging transport crates around and or moving them on a bumpy cart may create negative association for the bird, due to an uncomfortable ride and decrease the likelihood that the bird will go in the box on future occasions. If the perch is to low for the bird, their tail feathers may get painted with fecal matter which does not look good on presentation. Varikennel you are able to adjust the height of the perch.
- This species can be trained to voluntarily enter a crate either from the glove or directly from their enclosure. Continuous reinforcement of voluntary crate behaviors as well as dedication to their comfort and safety while in the crate is important to maintaining solid and reliable crate behavior.
- Being natural inhabitants of a variety of climates, barn owls are typically able to be used in a wide variety of temperatures. When transporting and using on programs, attention should be paid to the comfort of the individual and any signs of heat distress responded to accordingly.

Comments from the Rating System
- Buffalo Zoo: Non-imprinted specimens will be difficult for program use. They tend towards nervousness and they have difficulty adjusting to changes in their environment.
- Maryland Zoo in Baltimore: Limited handlers.
- Zoo New England, Stone Zoo: We have had a couple different imprinted birds, with mixed success. These birds can be a challenge, and do require experienced handlers.
- Pittsburgh Zoo & PPG Aquarium: Even with imprinted birds, they have still exhibited some nervousness and are a little more challenging than some of the other owl species.
