Owls are vulnerable in daylight, and crows will mob an owl to prevent them from sleeping
. Crows have an innate dislike of owls and use their daylight advantage to torment their largest predator. While there does not appear to be a definitive answer among the scientific community about why crows expend energy mobbing owls, the prevailing theory is that crows attack owls to reduce their risk of predation. Here are some ways to protect owls from crows:
- Install scare devices: A variety of devices can frighten a problematic owl.
Increasing human activity in the area will keep most owls at a distance.
Yelling and clapping hands, firing a gun loaded with blanks (it is illegal to shoot any owl), and banging cans together are all effective when an owl is nearby.
- Retain large dead or dying trees: Owls can use these trees as perch sites.
- Protect or plant hedgerows and thickets: These can attract small mammals that owls eat.
- Leave large grasslands alone or mow them only annually: This provides habitat for small mammals that owls eat.
- Install owl nest boxes for barred owls: This can provide a safe place for owls to roost.
- Install perch poles: This can provide a safe place for owls to perch.
It is important to note that poison bait has the potential to kill owls, so it is best to manage mice and rat problems other ways
. Additionally, when possible, stay away from nesting areas with aggressive birds until the young are flying (three to four weeks after eggs hatch) and the parents are no longer so protective.
If you must walk past a nest, wave your arms to make yourself look bigger and yell to let the birds know you are there.

What Are Some Effective Strategies Or Methods To Deter Crows And Protect Owls In Their Natural Habitats?
There are several effective strategies to deter crows and protect owls in their natural habitats.
Here are some of them:
To deter crows:
- Hang decoys like scarecrows or fake animals like owls, eagles, hawks, or snakes.
- Use reflective objects like reflective tape or holographic flash tape.
- Find out what sounds crows hate and use them to scare them away, such as recorded crow distress calls, loud bells, or fireworks sounds.
- Remove potential food sources like trash, compost, bird feeders, and pet food containers.
- Remove nesting areas.
- Try bird netting.
- Use wind chimes.
To protect owls:
- Use decoys of owls, eagles, hawks, or snakes to keep crows away.
- Attack the crows’ nesting place.
- Reduce outdoor lighting around your home at night, since crows are drawn to well-lit areas.
Are There Any Specific Adaptations Or Behaviors That Owls Possess That Aid In Their Defense Against Crows?
Crows and owls are natural enemies, and crows will often harass, peck, annoy, and mob an owl if they discover one in the daylight.
Owls are vulnerable in daylight, and a murder of crows will mob an owl to prevent them from sleeping.
Some of the larger breeds of owl, such as the great-horned owl, will opportunistically hunt young crows if they come upon them.
However, generally, owls do not predate crows.
Crows are intelligent and have the ability to identify things that have attempted to harm them and share that knowledge with the rest of the flock.
If an owl has taken a pass at, or successfully killed a crow, the rest of the flock will likely learn about it and take the next opportunity to exact revenge, even if the attack did not happen recently.
Some studies suggest that this mobbing behavior may reduce the likelihood of an owl killing a crow the next time it comes across one, which is a potential benefit to mobbing any owl a crow sees.
Are There Any Ongoing Research Or Conservation Efforts Focused On Minimizing The Impact Of Crow Predation On Owl Populations, And If So, What Are Some Of The Key Findings Or Recommendations?
There is limited information on ongoing research or conservation efforts focused on minimizing the impact of crow predation on owl populations.
However, there are some key findings and recommendations from existing studies and articles:
- Owls prey on the nests of crows in search of an easy meal, but most owls do not seek out hatchlings to prey upon.
The horned Owl, barred owl, and other larger owl species are most likely to attack crows nests.
- Crows attack owls to reduce their risk of predation.
Owls do sometimes eat crows, and they frequently have overlapping nest habitats, which can lead to conflict.
- Birds who engage in mobbing owls are much less likely to be targeted for predation by those owls.
Birds that do not engage in mobbing owls are much more likely to be targeted for predation by owls.
So by preemptively mobbing owls, crows reduce their overall risk of predation.
- Some studies suggest that this mobbing behavior may reduce the likelihood of an owl killing a crow the next time it comes across one, which is a potential benefit to mobbing any owl a crow sees.
- There is a need for further research to evaluate the population impacts of predation by owls on other bird species.
- Wildlife populations produce more offspring than their habitats can support.
These surplus individuals eventually die of starvation, disease, or predation.
