Quick Answers

Here are quick answers to some common questions about wasps and hummingbirds:

Wasps generally do not hunt hummingbirds for food. They are far more likely to see them as a threat than as prey.

Wasps may attack hummingbirds to defend a food source or nesting area. This can injure or even kill hummingbirds.
Some wasp species like yellowjackets are more aggressive and prone to unprovoked attacks.
Wasps are likely to be most dangerous to smaller hummingbird species and babies.

Stings from wasps can be quite painful to hummingbirds and may become infected.
Providing wasp-proof feeders and nesting spots can help protect hummingbirds.
Hummingbirds may change their behavior to avoid areas with abundant wasp activity.

Do Wasps Hunt Hummingbirds?

Wasps are carnivorous insects that feed on other bugs, spiders, caterpillars, and sometimes even small vertebrates. However, they do not typically see hummingbirds as prey. One reason is that hummingbirds are fast and agile flyers that are difficult to catch. Additionally, hummingbirds have sharp bills that can be used to stab wasps in self-defense. So attempting to hunt a hummingbird carries a high risk of injury for a wasp with little reward.

Wasps rely on hunting smaller and more vulnerable invertebrates for their protein intake. They may feed on items like flies, beetles, grubs, earthworms, and spiders. These prey items are much easier for wasps to safely capture and kill. Hummingbirds do not provide enough meat for wasps to make them worthwhile hunting targets.

There are some exceptions where wasps have been documented preying on hummingbirds. In most cases this involves larger predatory wasp species like hornets or murder hornets. The giant Asian hornet for example has been known to attack hummingbirds on rare occasions. However, the vast majority of wasp species have no interest in pursuing hummingbirds for food.

When Do Wasps Attack Hummingbirds?

While they do not hunt hummingbirds, wasps can still be very dangerous to the birds. Wasps are highly territorial creatures and will defend their nests and food resources vigorously. They will attack any animal that gets too close, including hummingbirds.

Here are some of the most common situations that can instigate wasp attacks on hummingbirds:

Defense of a food source – Wasps feed on sugary substances like flower nectar and tree sap. They will attack hummingbirds that approach a food source they have claimed.

Defense of the nest – Nesting areas are fiercely defended by wasps. Any hummingbird that flies too close may be attacked.
Mistaken identity – Fast-moving hummingbirds can sometimes be mistaken for predatory insects or other threats, triggering an attack.
Accidental collisions – If a hummingbird accidentally collides with a wasp or nest, the wasp colony will retaliate.

Provocation – Some species of wasps are more aggressive by nature and will attack with little provocation.

In most cases, the wasp is simply trying to neutralize a perceived threat to itself or its colony when it attacks a hummingbird. The wasp likely does not intend to hunt the hummingbird for food.

Which Species of Wasps Are Most Aggressive Toward Hummingbirds?

Not all wasp species exhibit the same level of aggression toward hummingbirds. Here are some of the most problematic types:

Yellowjackets – Smaller and more aggressive than other wasps, yellowjackets will vigorously defend their nests.
Hornets – Larger and more predatory wasps, hornets are more liable to attack without provocation.
Paper wasps – These wasps build paper nests on eaves and ledges that hummingbirds can easily collide with.

Red wasps – Fiercely defensive, red wasps will sting repeatedly when their nest is threatened.

In contrast, here are some wasp species that are less aggressive and dangerous to hummingbirds:

Mud daubers – These wasps rarely sting and their nests tend to be out of the way.

Cicada killers – They specialize in hunting cicadas and ignore hummingbirds.
Spider wasps – Busy hunting spiders, they avoid conflicts with hummingbirds.

Knowing which wasp species pose the most hazard in your area can help you take steps to protect hummingbirds from potential attacks.

Are Baby Hummingbirds at Risk?

Young hummingbirds that have recently left the nest are especially vulnerable to wasp attacks. There are a few reasons for this:

Babies and fledglings are smaller, weaker, and less able to defend themselves.
They lack the flying skills and experience to evade wasps.

Their curiosity leads them to explore areas where they may disturb wasp nests.
They have an unlearned tendency to investigate anything, including wasps.

Furthermore, the consequences of wasp attacks are more serious for young hummingbirds. Their small bodies experience more damage from just one or two stings. The toxicity of venom impacts their systems more strongly. And if injured, they lack the resilience and resources to recover that adult hummingbirds have.

Here are some useful tips to help protect baby hummingbirds from wasps:

Install wasp traps or nesting deterrents away from hummingbird feeders and nests.
Keep a watch for any wasp nests forming near hummingbird activity.

Clean up fallen fruit and debris that could attract wasps.
Provide shrubbery and hiding places for young hummingbirds to take cover.
Let young hummingbirds strengthen and mature before removing nests or deterrents.

Taking some simple precautions can help create a safer area for vulnerable young hummingbirds to develop and learn to fly.

How Do Wasp Stings Affect Hummingbirds?

Wasp stings can be quite painful and dangerous for hummingbirds. Here are some of the effects:

Excruciating pain – Wasp venom contains toxic chemicals that cause immediate, burning pain.

Swelling and infection – The sting area swells up and may become infected.
Impaired flight – Swelling around wings or eyes can prevent flying and seeing.
Damage to vital organs – Stings inside the mouth or throat can damage breathing and swallowing.

Illness – The venom may make a hummingbird sick if stung multiple times.
Death – Multiple stings can be fatal, especially for smaller species.

Here is an example of how wasp stings could potentially kill a hummingbird:

A hummingbird gets stung on the face when nearing a wasp nest.
The eyes and throat swell, making it hard to see and breathe.
Additional stings occur as the bird frantically flees the angry wasps.

The wings and chest area swell up reducing flight ability.
The toxins make the hummingbird disoriented and weak.
It can no longer fly properly or evade dangers, eventually dying from stress, exposure, or additional stings.

While not always fatal, wasp venom can clearly have severe detrimental effects on hummingbirds. Quickly removing wasp threats decreases the risks.

Do Hummingbirds Avoid Wasp Hotspots?

Hummingbirds rely strongly on vision and memory. After negative experiences, they will learn to avoid areas where they have encountered wasps. Some behavioral changes hummingbirds may exhibit include:

Avoiding feeders – They will skip feeders if wasps are present.

Visiting at different times – They may only feed early or late to avoid active wasps.
Approaching quickly – Hummingbirds may zip in and out of hazardous areas.
Scanning for threats – Increased looking around for dangers.

Knowing wasp nest locations – Having learned where nearby nests are.
Losing trust – Becoming warier around areas they were stung before.

Studies tracking hummingbird movements show they purposefully avoid places where they have encountered wasps previously. Their spatial memory and conditioning helps them survive by changing their foraging patterns.

How to Protect Hummingbirds from Wasps

Here are some effective tips for reducing wasp threats and creating safer spaces for hummingbirds:

Use wasp traps or other deterrents away from hummingbird areas.
Inspect for and remove any visible wasp nests regularly.

Choose smooth-sided feeders that wasps cannot cling onto.
Clean up fallen fruit and debris that attract wasps.
Provide shrubs and shelters for hummingbirds to hide in.

Use insecticidal sprays only if necessary and with extreme care.
Avoid using scented products, perfumes, and bright colors.
Position hummingbird feeders away from likely wasp flight paths.

Consider suspended or enclosed feeder designs.
Plant bee and wasp favorite flowers away from hummingbird zones.

With some thoughtful landscaping choices and smart feeder placement, we can enjoy both wasps and hummingbirds in our environments safely.

Conclusion

Wasps and hummingbirds naturally overlap in their needs for habitat and food sources. This inevitably brings them into contact and sometimes conflict. While wasps do not directly hunt hummingbirds, they can still injure or kill them with their stings. Smaller hummingbird species and babies are especially at risk. Fortunately, there are steps we can take to reduce wasp threats by using traps, modifying feeders, and making landscaping choices that promote safety for hummingbirds. Understanding the conditions that trigger wasp attacks enables us to be proactive about prevention. With proper precautions, we can allow hummingbirds and wasps to peacefully coexist in a shared space.
