Hummingbirds are amazing little birds that have captured the fascination of people for centuries. One of the most commonly asked questions about hummingbirds is whether they catch and eat bugs right out of the air as they fly around. In this article, we’ll explore the answer to this question and look at some related aspects of hummingbird behavior and diet.
The Short Answer
Yes, hummingbirds do sometimes eat insects directly out of the air as they fly. Their incredible aerial agility allows them to precisely pluck tiny bugs and flies midflight. While nectar is their main food source, hummingbirds get essential protein, calories, and nutrients from eating insects and spiders.
How Hummingbirds Catch Insects in Flight
Hummingbirds have several physical adaptations that enable them to snatch insects while in flight:
- Exceptional vision – Hummingbirds have sharp vision that lets them accurately spot and target tiny insects as small as fruit flies or gnats.
- Swift reflexes – They have rapid response times to instantly react to sights and movement.
- Maneuverability – Their wings can beat up to 80 times per second, allowing for precision flying.
- Needle-like bill – Their slender, pointed bill is an ideal tool for skewering soft-bodied insects.
By combining these traits, hummingbirds can adeptly pluck insects right out of the air with perfect timing. They grab bugs on the wing by opening their bill and snapping it shut around the insect in a fraction of a second.
Why Hummingbirds Eat Insects
While hummingbirds get most of their nutrition from drinking flower nectar, they also depend on eating insects for some important benefits:
- Protein – Insects provide a high-quality source of protein and amino acids that hummingbirds can’t get from nectar alone.
- Fat – The fat in insects gives hummingbirds an essential energy boost.
- Micronutrients – Eating bugs provides hummingbirds with important vitamins, minerals, and trace nutrients not found in nectar.
Without insects and spiders to round out their diet, hummingbirds would not thrive. Although nectar remains their primary food, bugs provide crucial nutritional components hummingbirds need to survive and stay healthy.
When and Where Hummingbirds Catch Insects
Hummingbirds will opportunistically eat insects whenever they come across them during the day. But there are certain times and places they are most likely to be insect-hunting:
- Early morning – Hummingbirds often hunt for bugs first thing in the morning before visiting flowers.
- Above water – Bugs tend to swarm over lakes, streams, and irrigation ditches, attracting hummingbirds.
- Forest gaps – Openings in woodlands host lots of insects that hummingbirds snatch up.
- Sap flows – Oozing tree sap attracts bugs, leading hummingbirds to hawk the swarms.
- Spider webs – Hummingbirds skillfully pick spiders and bugs off webs.
Insects may make up a larger portion of a hummingbird’s diet at certain times of year when nectar sources are less abundant such as early spring and late fall.
What Kinds of Bugs Do Hummingbirds Eat?
Hummingbirds are opportunistic and will eat a wide range of insect prey based on availability, including:
- Mosquitoes
- Flies
- Aphids
- Beetles
- Caterpillars
- Ants
- Bees
- Grasshoppers
- Spiders
They prefer soft-bodied insects like mosquitoes, flies, aphids, and spiders which are easy to snatch out of the air. Harder shelled bugs like beetles and grasshoppers require a bit more effort to crush and eat.
Do Hummingbirds Eat While Hovering?
Yes, hummingbirds have an amazing ability to eat bugs while hovering in midair. Here’s how they do it:
- The hummingbird spots an insect and flies toward it.
- It precisely positions its body underneath the bug.
- The hummingbird’s wings beat rapidly to maintain a fixed hover position.
- It snaps its head upward and catches the insect in its bill.
- While still hovering, the hummingbird crushes and swallows the insect.
This all happens in just a few seconds. Eating while hovering allows hummingbirds to keep a lookout for more insects to catch without having to constantly land and take-off.
Do Male and Female Hummingbirds Eat Bugs?
Both male and female hummingbirds supplement their diet with insects. However, there are a couple differences between the sexes:
- Females tend to eat more bugs while breeding – The extra protein helps females produce healthy clutches of eggs.
- Males eat more insects during courtship – Additional protein and calories help males carry out elaborate courtship displays.
The bottom line is that bugs are a valuable food source for both male and female hummingbirds throughout the year.
Do Baby Hummingbirds Eat Insects?
Yes, insects and spiders are an essential part of the diet for baby hummingbirds. Here’s a look at how their insect-eating changes as they grow:
- Newly hatched chicks – Too small and weak to catch bugs, they rely on regurgitated insects from the mother.
- Nestlings – The mother brings whole, live insects to the nest for the chicks to eat.
- Fledglings – Young hummingbirds pluck bugs out of the air clumsily as they learn to fly and hunt.
Insects provide growing hummingbird chicks with abundant calories and protein crucial for development. As they mature, catching insects teaches fledglings survival skills.
How Often Do Hummingbirds Eat Bugs?
On average, bugs and spiders make up about 15-20% of a hummingbird’s diet. But insect consumption can vary quite a bit:
- In colder months when insects are scarce, bugs may be less than 5% of their diet.
- During summer when insects thrive, over 30% of their food intake could be bugs.
- Young hummingbirds eat a higher proportion of insects, often 25-45% as they grow.
Hummingbirds are opportunistic and their rate of insect consumption depends largely on seasonal availability. But bugs remain a constant part of their nutritional regimen year-round.
Daily Rate of Insect Consumption
Research on broad-tailed hummingbirds found that, on average, they eat about 50-100 insects per day along with their normal nectar diet. However, maximum consumption was 300 insects in a day!
| Age | Average # of Insects Consumed Per Day | Maximum # Consumed Per Day |
|---|---|---|
| Adult | 50-100 | 300 |
| Nestlings | 400-500 | 800 |
Nestlings have the highest bug consumption rates as they rely heavily on insects for growth and development.
What Physical Adaptations Help Hummingbirds Catch Bugs?
Hummingbirds have several specialized physical features and capabilities that enable them to effectively hunt insects, including:
- Wings – Their small wings beat up to 80 times per second, allowing extreme maneuverability in flight.
- Feet – Short legs and feet are used like hands to snatch bugs off surfaces.
- Vision – Exceptional eyesight detects tiny insects up to 30 feet away.
- Bill – Their needle-like bill impales soft bodied-insects.
- Tongue – A forked tongue covered in hair-like filaments is ideal for capturing bugs.
These adaptations give hummingbirds an impressive set of insect-catching tools unmatched by other birds.
Unique Insect-Hunting Behaviors
Hummingbirds display some clever insect hunting behaviors and techniques:
- Hover-hawking – Hovering in one spot while plucking bugs out of the air.
- Flycatching – Darting after and catching insects already in flight.
- Gleaning – Picking stationary insects off of leaves, branches, or the ground.
- Skimming – Flying just above the water to catch emerging aquatic insects.
These specialized hunting methods allow hummingbirds to take full advantage of any insect food source they encounter.
Interesting Facts About Hummingbirds Eating Insects
- A hummingbird’s breathing and heart rate increase dramatically when catching bugs due to the extra exertion required.
- Younger hummingbirds get insects stuck to their tongues as they learn to catch bugs, until their skills improve.
- Fledgling hummingbirds will sometimes steal insects from spider webs instead of catching their own.
- Male hummingbirds catch more insects during courtship displays to impress potential mates.
- Tropical hummingbird species tend to eat fewer insects since nectar sources are more constantly available.
Key Takeaways
