What Do Hummingbirds Eat? Complete Guide to Their Diet in Every Season
Hummingbirds are among the most energetic birds on Earth, and their diet is the key to sustaining their extreme metabolism. If you’re wondering what do hummingbirds eat, the short answer is: primarily flower nectar for sugar and small insects and spiders for protein. Throughout the year, their hummingbird diet shifts with the seasons, from abundant spring blooms to migration-heavy fall feeding.
This guide explains what hummingbirds eat, how their diet changes with season, species, and life stage, and how you can attract them to your garden with the right plants and feeders.
The Basics of a Hummingbird’s Diet
Hummingbirds have a two-part diet designed to meet both energy and protein needs. Their feeding habits are shaped by their high metabolism, tiny body size, and constant need for calories.
Nectar: The Primary Energy Source
Nectar is the main food source for all hummingbird species. It provides high concentrations of sucrose and other sugars required to fuel their rapid wingbeats and constant movement. While the exact sugar concentration varies by plant, many hummingbird-favorite flowers produce nectar in the 15–25% sugar range.
Common nectar sources include bee balm (Monarda), salvia (especially red and orange varieties), cardinal flower (Lobelia), and trumpet honeysuckle. These plants typically have long, tubular, brightly colored (especially red) flowers, which match the hummingbird’s long bill and tongue.
Insects and Spiders: The Protein Source
To build muscle, raise chicks, and maintain overall health, hummingbirds also eat small insects and spiders, such as:
- Gnats
- Fruit flies
- Aphids
- Small spiders
These prey items supply essential amino acids, vitamins, and minerals that nectar alone cannot provide. Insects become especially important during the breeding season, when adults need extra protein for egg production and chick growth.
Tree Sap: A Backup Energy Source
When flowering plants are scarce, some hummingbirds will drink tree sap from holes made by sapsuckers or woodpeckers. Though less sweet than floral nectar, sap still offers a usable source of sucrose for short-term energy needs.
This behavior is especially common in North American species like the Ruby-throated Hummingbird during late fall and early spring.
What Do Hummingbirds Eat in Each Season?
Hummingbirds adjust their diet based on the seasonal availability of flowers and insects. Understanding these seasonal hummingbird diet patterns helps you plan your garden and feeders more effectively.
Spring: Rebuilding After Migration
- Main food: Fresh nectar from early-blooming flowers
- Additional: Insects and spiders for protein (especially important for breeding)
In spring, early-blooming plants such as trumpet honeysuckle, bee balm, and salvia become critical food sources. Adult hummingbirds also increase insect consumption to support egg production and recovery from migration.
Summer: Peak Energy and Breeding
- Main food: Peak nectar production from summer flowers
- Additional: High insect abundance supports chick-rearing adults
During summer, hummingbirds exploit the maximum bloom period of many garden and wild plants. This is also the time when they hunt the most insects, especially when feeding nestlings that require high protein.
Fall: Preparing for Migration
- Main food: Increased insect and spider consumption
- Purpose: Build fat reserves for long migratory journeys
As flowers begin to fade, hummingbirds shift toward more insects and spiders to store energy. This is the best time to ensure your garden has late-blooming, nectar-rich plants and reliable feeders to support migrating birds.
Winter: Survival in Warmer Climates
- Main food: Remaining flowers and insects in warmer regions
- Note: Many species migrate to warmer climates where food is more reliable
In colder areas, most hummingbirds have migrated south. In warmer regions (e.g., parts of the U.S. Southwest, Mexico, Central America), some species remain year-round, feeding on whatever flowers and insects are still available.
Diet Differences by Life Stage and Gender
While all hummingbirds rely on nectar and insects, their feeding habits vary slightly depending on gender and life stage.
Female Hummingbirds During Egg-Laying
Females consume more protein-rich insects during the breeding season to support egg production, nest building, and chick-rearing energy needs. This higher protein intake is essential for producing strong, healthy eggs and sustaining the energy demands of feeding nestlings.
Male vs. Female Hummingbird Diet
| Aspect | Male | Female |
|---|---|---|
| Main foods | Nectar, insects, spiders | Nectar, insects, spiders |
| Protein emphasis | Moderate | Higher during the breeding season |
| Nesting role | Often territorial, less nesting | Builds nest, incubates, feeds chicks |
Both sexes rely on the same basic food types, but females need more protein during nesting.
Baby and Fledgling Hummingbirds
- Baby hummingbirds: Do not eat directly; they are fed by their mother.
- Mother’s diet for chicks: A mix of partially digested insects and nectar.
- Fledgling hummingbirds: Just left the nest but still learning to forage; they gradually transition to an adult-like diet of nectar and insects.
The mother’s mixed diet provides baby hummingbirds with both energy (sugar) and protein (insects) needed for rapid growth.
Migration Diet
During migration, hummingbirds need extra energy to cover long distances, so they increase their consumption of nectar and insects. They often rely heavily on feeders and blooming plants along their route. Providing reliable food sources, especially in the fall, can significantly support migrating populations.
Different Hummingbird Species and Their Food Preferences
Different species show preferences based on habitat and available flowers.
| Species | Preferred Flowers / Plants | Notes |
|---|---|---|
| Ruby-throated | Trumpet creeper, bee balm | Prefers red/orange tubular flowers |
| Anna’s | Salvia, fuchsia, garden plants | Often visits residential gardens |
| Rufous | Many red tubular flowers | Aggressive feeder, wide food range |
| Black-chinned | Desert willow, various flowers | Frequently uses feeders |
| Calliope | Larkspur, paintbrush | Feeds on alpine and mountain flowers |
| Broad-tailed | Columbine, sage | Alpine habitat specialist |
| Costa’s | Agave, chuparosa | Deserts and dry slopes |
Understanding species-specific preferences helps you choose the best plants for your region.
Do Hummingbirds Eat Fruit or Seeds?
Do Hummingbirds Eat Fruit?
Hummingbirds do not eat fruit as a primary food source, but they may sip juice from overripe or damaged fruit such as apples, grapes, berries, and oranges when nectar is scarce. Fruit is not a reliable source of protein or structured nutrition, but it can act as a backup sugar source.
Do Hummingbirds Eat Seeds?
Hummingbirds do not feed on seeds at all. Seeds do not provide the high sugar or protein they need, and although they may accidentally ingest tiny particles while catching insects, seeds are not part of their normal diet. If you’re trying to attract hummingbirds, focus on nectar-rich flowers and feeders rather than seed mixes.
What Time of Day Do Hummingbirds Eat?
Hummingbirds are most active during the early morning and late afternoon. These times often coincide with higher nectar production in some flowers and greater insect activity. They eat frequently throughout the day to maintain energy levels due to their extremely high metabolism.
How to Attract Hummingbirds With Food and Plants
If you want to support hummingbirds in your garden, focus on three main strategies: plants, feeders, and safe conditions.
Plant Nectar-Rich, Hummingbird-Friendly Flowers
Choose plants that are brightly colored (especially red, orange, pink), tubular in shape, and scentless or lightly scented, since hummingbirds rely more on sight than smell.
Excellent options include bee balm (Monarda), salvia (red, blue, purple varieties), cardinal flower (Lobelia), trumpet honeysuckle, hummingbird sage, and petunias. These plants provide both nectar and insects, giving hummingbirds a dual food source.
Set Up Hummingbird Feeders Safely
Feeders can be especially valuable during:
- Late spring departure
- Fall migration
- Winter in warmer regions
How to make hummingbird nectar (sugar water):
-
Boil water to kill bacteria and mold.
-
Remove from heat and add white granulated sugar (4 parts water to 1 part sugar).
-
Stir until the sugar fully dissolves.
-
Let the mixture cool completely before filling the feeder.
-
Store unused nectar in the refrigerator for up to one week.
Important tips include avoiding honey, brown sugar, artificial sweeteners, or food coloring, cleaning feeders regularly to prevent mold and bacterial growth, and placing feeders in safe locations away from predators like cats.

FAQs About Hummingbird Food
Do hummingbirds change color based on what they eat?
No. Hummingbirds do not change their feather color based on diet. Their colorful plumage comes from microscopic structures in the feathers that reflect light. A healthy diet can improve overall vitality and appearance, but it does not alter color.
What insects do hummingbirds eat?
Common insects in a hummingbird’s diet include gnats, fruit flies, aphids, small spiders, and occasionally ants, which provide essential protein and amino acids.
Do male and female hummingbirds eat different foods?
Both eat nectar, insects, and spiders, but females consume more protein-rich insects during the breeding season to support egg production and chick-rearing.
What do baby hummingbirds eat?
Baby hummingbirds are fed by their mother with a mix of partially digested insects and nectar, which supplies both energy and protein for growth.
What do fledgling hummingbirds eat?
Fledgling hummingbirds (just out of the nest) gradually learn to catch small insects and feed on nectar from flowers and feeders, while still relying partly on their parents as they transition to full independence.
Do hummingbirds eat in the rainforest or desert?
In rainforests, they feed on exotic flowers such as heliconias and passionflowers as well as tropical insects. In deserts, they adapt by using desert plants like agave and ocotillo, which produce sugar-rich nectar even in harsh conditions, as well as desert insects for protein.
Final Words
By understanding what hummingbirds eat and how their diet changes by season, species, and life stage, you can create a garden and feeding setup that truly supports these remarkable birds. Planting nectar-rich flowers, providing safe feeders, and offering clean water will help you enjoy hummingbirds year after year.
