Hummingbirds, those tiny jewels of the sky, are a marvel to behold. Their vibrant colors and dazzling aerial acrobatics captivate nature lovers everywhere. One of the most frequently asked questions about these enchanting birds is: “What Do Hummingbirds Eat?” These energetic dynamos have incredibly high metabolisms, requiring them to consume a significant amount of food daily just to survive. Let’s delve into the fascinating world of hummingbird diets and explore exactly what fuels their incredible lives.
The Importance of Nectar in a Hummingbird’s Diet
Nectar is the cornerstone of a hummingbird’s diet, providing them with the essential carbohydrates they need for energy. This sugary liquid, produced by flowers, is a readily available and easily digestible fuel source perfectly suited to their high-energy lifestyle.
Hummingbirds have evolved alongside nectar-producing flowers, developing long, slender bills and tongues specially adapted to access nectar deep within floral blooms. Their tongues are not simple straws; they are forked and fringed at the tip, designed to lap up nectar quickly and efficiently through capillary action.
While hummingbirds are not particularly picky eaters when it comes to nectar sources, they do show preferences. They are attracted to brightly colored flowers, especially red, orange, and pink, often with a tubular shape that fits their bills. Native plants are particularly crucial, as hummingbirds have co-evolved with local flora, ensuring optimal nectar availability and nutritional balance.
Examples of flowers that hummingbirds love include:
- Trumpet vine: Known for its vibrant orange, trumpet-shaped flowers.
- Cardinal flower: A striking red flower that stands out in any garden.
- Bee balm: Offers a burst of color and fragrant nectar.
- Salvia: Comes in various colors and provides a long-lasting nectar source.
- Fuchsia: Dangles delicate, nectar-rich blossoms.

Insects: The Essential Protein Source for Hummingbirds
While nectar provides the energy hummingbirds need to fly and hover, it lacks protein, fats, vitamins, and minerals crucial for growth, especially for young hummingbirds, and overall health. This is where insects come into play. Insects are a vital, often overlooked, component of a hummingbird’s diet, providing the necessary protein to build and repair tissues, produce enzymes, and support their immune system.
Hummingbirds are adept insect hunters, catching their prey in various ways:
- In-flight capture: They can snatch tiny flying insects like gnats, fruit flies, and mosquitoes right out of the air with remarkable agility.
- Gleaning from foliage and spiderwebs: Hummingbirds will also pluck insects and spiders from leaves, branches, and even spiderwebs.
- Attraction to sap flows: They are attracted to tree sap, not just for the sap itself but also for the insects that are drawn to it.
Some common insects that hummingbirds consume include:
- Gnats and fruit flies: Small and abundant, these are easy targets for hummingbirds.
- Mosquitoes: Providing a valuable ecosystem service, hummingbirds help control mosquito populations.
- Spiders: A significant source of protein and other nutrients.
- Aphids: Often found on plants, providing a convenient meal.
- Beetles and ants: Smaller beetles and ants can also be part of their insect diet.

Beyond Nectar and Insects: Other Food Sources
While nectar and insects constitute the majority of a hummingbird’s diet, they may occasionally supplement their meals with other food sources:
- Tree sap: As mentioned earlier, hummingbirds are attracted to tree sap, both for the sap itself (which contains some sugars and minerals) and the insects it attracts.
- Pollen: While not a primary food source, hummingbirds inadvertently consume pollen while feeding on nectar. Some studies suggest they may derive a small amount of protein and other nutrients from pollen.
- Hummingbird feeders: For many people, hummingbird feeders are a way to attract these beautiful birds to their yards and gardens. Feeders filled with a simple sugar-water solution (1 part white sugar to 4 parts water, boiled and cooled) can provide a supplemental energy source, especially during times when natural nectar sources are scarce, such as during migration or breeding season. It’s crucial to avoid using honey, brown sugar, or artificial sweeteners, as these can be harmful to hummingbirds. Regular cleaning of feeders is also essential to prevent mold and bacteria growth, which can be detrimental to hummingbird health.
Creating a Hummingbird-Friendly Habitat
Understanding what hummingbirds eat is the first step in creating a welcoming habitat for them. By planting nectar-rich native flowers and avoiding pesticide use (which eliminates their insect food source), you can make your garden a hummingbird haven. Supplementing with a properly maintained hummingbird feeder can further support these amazing birds, especially during migration and breeding seasons.
By providing both nectar and insect sources, you can help ensure these tiny, energetic creatures thrive in your area and continue to bring joy and wonder to our world. Remember, a healthy hummingbird is a well-fed hummingbird, and their diet is a delicate balance of sugary nectar and protein-packed insects.
