What You'll Learn
Nectar from flowers
Nectar is the primary food source for hummingbirds. The nectar of various flowers, such as bee balm, salvia, cardinal flowers, petunias, coral honeysuckle, and fuchsia, provides the sugar that fuels their high-energy lifestyle. The long, tubular shapes of these flowers are well-suited to the long bills of hummingbirds, allowing them to probe for nectar at the bottom of the corollas.
Hummingbirds are attracted to red, tubular flowers, which they visit repeatedly due to their long-term memory. This symbiotic relationship benefits the plants as well, as the birds' tongues and beaks pick up pollen while feeding, facilitating pollination.
To meet their high energy requirements, a hummingbird may need to visit hundreds of flowers per day, consuming nectar equivalent to three times their body weight. In addition to natural sources, hummingbirds have come to rely on human-made feeders, which simulate natural nectar by mixing one part white sugar with four parts water.
While nectar provides the sugar that hummingbirds need, it does not fulfil their requirements for protein, amino acids, vitamins, and minerals. Therefore, they must supplement their diet with other food sources to maintain a balanced and healthy diet.

Sugar and water solutions
Hummingbirds feed on nectar from various types of flowers, such as bee balm, salvia, cardinal flowers, petunias, honeysuckle, and coral bells. These flowers have long, tubular shapes that are perfect for hummingbirds to reach with their long bills. However, the sugar and water solution provided by humans in feeders is also an important food source for hummingbirds.
The sugar water solution should be placed in a red feeder, as this colour attracts hummingbirds. It is important to avoid adding any dyes, honey, molasses, fruit juice, or artificial sweeteners to the solution, as these could be dangerous to the birds. Instead, a simple mixture of sugar and water is best.
Hummingbirds require a constant supply of energy due to their high-metabolism and active lifestyles. As a result, they may eat up to three times their body weight in a day. This means that a hummingbird may visit hundreds of flowers per day to find enough nectar. Therefore, the sugar and water solution provided by humans is an important supplement to their diet.
In addition to sugar and water solutions, hummingbirds also consume insects and spiders to obtain protein, amino acids, vitamins, and minerals. While nectar is their primary food source, it does not meet all their nutritional needs. Insects provide the fat, protein, and salts that are crucial for the birds' health, especially for rapidly growing hatchlings.

Insects
Hummingbirds eat a variety of insects, including spiders, mosquitoes, aphids, fruit flies, gnats, midges, leafhoppers, ants, and insect eggs. They catch insects in several ways, including picking them from bark, flowers, or leaves, plucking them from spider webs or sticky tree sap, or hawking them in mid-air. They may also forage for insects in the sap wells drilled in trees by sapsuckers.
Hummingbirds must eat several dozen insects each day to meet their protein requirements. They will eat many more if they need to feed hatchlings or if they are migrating. During the breeding season, females consume more protein-rich insects to develop healthy eggs and obtain enough energy to raise their young.
The type of insects hummingbirds eat depends on the season. In spring and summer, they eat more insects, including spiders, fruit flies, and gnats, as these are the seasons when flowers are in bloom and nectar is more abundant.

Spiders
Hummingbirds use various methods to capture spiders, including hover-gleaning, where the bird hovers near a spider web or leaf and uses its bill and tongue to capture the spider or the insects trapped in the web. They may also pluck spiders from their webs, a method known as hover-hawking, where the bird zigzags through swarms of insects, picking them off one by one.
The presence of spiders in a garden is beneficial for attracting hummingbirds. Native plants that attract insects, such as broadleaf ironweed, purple ironweeds, and yellow or white goldenrods, will also lure predatory spiders to their pollen and nectar. Creating a habitat that supports a diverse range of insects and spiders will make your garden particularly appealing to hummingbirds.
While the exact percentage may vary, it is clear that spiders and insects make up a significant portion of a hummingbird's diet. Dr. Doug Tallamy estimates that 80% of a hummingbird's diet consists of insects and spiders, with nectar being a supplementary source of energy. This high-protein diet may help hummingbirds tolerate colder conditions and sustain their high metabolic rate.

Fruits
While nectar is the primary food source for hummingbirds, they also eat a variety of fruits. Certain ripe or juicy fruits can attract hummingbirds. They have been known to sip the juices of berries, apples, oranges, and pears if they are peeled, cut open, or if the flesh is otherwise exposed.
Hummingbirds are attracted to the vibrant colours of flowers and the nectar they provide. They have long, thin, and flexible tongues that allow them to reach the nectar at the bottom of tubular flowers. However, they also require other nutrients such as protein, amino acids, vitamins, and minerals, which they obtain from insects and other food sources.
Hummingbirds have a high metabolism and are constantly on the move, burning energy quickly. To meet their energy needs, they may consume up to three times their body weight in sugar and water solutions, also known as nectar, each day. This means that a single bird might need to visit hundreds of flowers to find enough nectar.
In addition to nectar, hummingbirds eat a variety of insects, larvae, insect eggs, and spiders. These provide the protein, fat, and salts that are crucial for their health and the development of their hatchlings. They may also eat tree sap, especially when nectar is scarce, and have been observed consuming ashes and sand, possibly as a source of minerals and salts or to obtain insects.
Hummingbirds are resourceful foragers, adapting their diet based on the availability of food sources and the season. While they primarily feed on nectar during spring and summer, they include more insects in their diet during these seasons as well.

Frequently asked questions
A hummingbird's diet consists of nectar, insects, and spiders. They also eat tree sap, pollen, and the juices of certain fruits.
Nectar is a sugar and water solution that provides hummingbirds with their primary energy source. It is usually sourced from flowers, but can also be provided by humans in feeders.
Hummingbirds eat small insects like gnats, fruit flies, mosquitoes, aphids, and ants. They also eat larvae, insect eggs, and spiders to get their required amount of protein and other nutrients.
Hummingbirds have a high metabolism and burn a lot of energy while on the move, so they need to eat up to three times their body weight in a day.
Hummingbirds can catch insects in several ways, including gleaning or picking them from bark, flowers, or leaves, hawking them in mid-air, or plucking them from spider webs or sticky tree sap.
