What Hummingbirds Need: Diet, Habits, and Garden Habitat
Explore the fascinating world of hummingbirds: their diet, unique behavior, and how to create the perfect backyard haven for these vibrant pollinators.
Hummingbirds are among nature’s most mesmerizing creatures, celebrated for their iridescent plumage, acrobatic flight, and tireless appetite. But what exactly do hummingbirds need to thrive, and how can you transform your outdoor spaces into a sanctuary for these tiny avian wonders? This article explores the essential requirements of hummingbirds, from their dietary preferences and foraging habits to the social structure of their lives and practical tips on crafting a garden these birds will flock to.
Hummingbirds: Tiny Birds with Big Needs
Hummingbirds, belonging to the family Trochilidae, are the only birds capable of sustained hovering and even flying backwards. Their wings beat between 50–80 times per second, and some can reach speeds of up to 60 miles per hour during courtship dives. Their minute size belies an immense metabolic demand: hummingbirds have among the highest weight-relative energy requirements of any animal.
- Heart rate: Up to 1,200 beats per minute at flight peak
- Respiratory rate: About 250 breaths per minute
- Daily food intake: Equivalent to their body weight in nectar, supplemented by insects
This voracious energy use dictates much of their behavior, movements, and even their evolutionary relationships with plants.
What Do Hummingbirds Eat?
Nectar is the predominant source of energy in a hummingbird’s diet, but it’s not their only need. For protein, fats, minerals, and other nutrients, these birds also pursue small arthropods.
- Sugar-rich nectar: Hummingbirds feed on the nectar of flowers, preferring blooms with high sucrose concentrations, typically averaging around 26%, which is much sweeter than most soft drinks.
- Insects and spiders: Especially vital during breeding season, hummingbirds catch tiny insects such as gnats, fruit flies, and spiders to provide essential proteins and nutrients for themselves and their chicks.
- Tree sap: In northern areas, when flowers are scarce, hummingbirds sometimes feed on sap-wells made by sapsucker woodpeckers, sneaking sips of flowing tree sap.
These foraging strategies are tailored to both seasonal and regional resource variation, and help explain why hummingbirds are often seen darting from bloom to bloom, garden feeder to garden feeder, or even flitting at wounds in tree bark.
Flower Preferences: What Plants Attract Hummingbirds?
Not all flowers are created equal in the eyes of a hummingbird. Over millions of years, many plant species have co-evolved with hummingbirds, leading to a suite of traits that make some blooms irresistible. Understanding floral selection is key to gardening for hummingbirds.
Traits of Hummingbird-Attracting Flowers
- Color: Red and orange blooms stand out to hummingbirds, who are attracted to these colors over many others, making color selection vital for your garden.
- Shape: Long, tubular flowers suit a hummingbird’s slender bill and tongue, excluding less-effective pollinators and maximizing nectar uptake for these birds.
- Nectar quality: High concentrations of nectar with ample sucrose content provide the crucial quick energy hummingbirds need.
- Flower position: Blooms that are pendant (hanging down) or positioned horizontally are easiest for hovering access.
- Timing: Gardens that offer overlapping bloom times ensure a continuous supply of food throughout migration and the breeding season.
What others are reading
Some tropically-adapted species have even developed a lock-and-key evolutionary partnership, where unique flower shapes perfectly match the bills of single hummingbird species, but most North American species are more generalist and will sample a variety of native (and sometimes ornamental) plants.
Recommended Plants for Hummingbird Gardens
- Bee Balm (Monarda)
- Trumpet Creeper (Campsis radicans)
- Penstemon (Penstemon spp.)
- Salvia (Salvia spp.)
- Columbine (Aquilegia canadensis)
- Crocosmia
- Native honeysuckle (Lonicera sempervirens)
- Coral bells (Heuchera)
- Cardinal flower (Lobelia cardinalis)
These selections offer a range of colors, heights, and blooming seasons, ensuring hummingbirds can always find nourishment nearby.
Pugnacious Pollinators: Hummingbird Social Behavior
Despite their diminutive stature, hummingbirds are famously territorial and feisty. Males, in particular, will defend nectar-laden patches or feeders with relentless vigor, engaging in aerial battles with rivals. This aggression is driven by the need to secure access to food resources, rather than for cooperation or socialization.
- Hummingbirds prefer to feed alone; groups are rare and usually result in chases or skirmishes.
- Male and female hummingbirds do not form pair bonds; after mating, females raise the young alone.
- Some species, primarily in the tropics, form leks: communal display grounds where males gather to attract females, but this is uncommon in North American species.
This characteristic independence extends to feeding and migration as well; hummingbirds navigate vast distances solo and do not rely on flocking to find resources.
Migration and Movement: Following the Bloom
Hummingbirds are renowned for their migratory feats. In North America, species like the Ruby-throated Hummingbird (Archilochus colubris) and Broad-tailed Hummingbird (Selasphorus platycercus) undertake journeys of thousands of miles between Central America and breeding grounds as far north as Canada.
- Migration is closely tied to flowering cycles, with birds timing their movements to coincide with peak nectar availability along their routes.
- Some species move upslope through mountain meadows as spring and summer progress, always staying with optimal blooming conditions.
- During migration, stopovers at rich food sites are critical refueling points.
For successful migration, a network of nectar-rich habitats is essential. Both wild landscapes and human-maintained gardens play crucial roles in sustaining birds through these taxing journeys.
Beyond Nectar: Other Requirements for Hummingbird Habitat
While nectar-rich plants are the cornerstone of any hummingbird-friendly space, a truly inviting habitat addresses the full life cycle needs of these birds.
- Insect diversity: A mix of native plants supports a healthy insect population, providing protein for adults and chicks.
- Safe perches: Small saplings, thin branches, and wires give hummingbirds rest spots and territorial lookout points.
- Nest sites: Deciduous trees and shrubs, particularly species with lichen and spiderweb availability, are prime nesting locations.
- Fresh water: Fountains, misters, and shallow birdbaths add important hydration and bathing opportunities.
- Minimized pesticide use: Reducing chemicals helps preserve the insects hummingbirds need and limits harmful exposure to the birds themselves.
Feeders: Benefits, Pitfalls, and Best Practices
Hummingbird feeders are one of the most popular ways people connect with these birds, but responsible use is key to promoting their health.
Pros of Feeders
- Provide a calorie-rich supplement during migration, breeding, or nectar scarcity
- Offer unique opportunities for close observation and photography
- Support birds in regions with hostile weather or poor native flower options
Potential Drawbacks
- Poorly maintained feeders can foster harmful mold and bacteria
- Overconcentration of birds may increase territorial fights and disease risks
- Improper nectar mixtures (such as use of honey, artificial dyes, or excess sugar) can harm hummingbirds
Best Practices for Feeders
- Use a simple solution of 1 part white sugar to 4 parts water
- Change nectar every 2–4 days, more often in hot weather
- Wash with hot water and rinse thoroughly each time you refill
- Avoid red dyes—feeders themselves attract with color, and dyes have no benefit
- Space feeders to minimize aggression and allow skittish birds feeding opportunities
Feeders are best seen as a supplement rather than a replacement for natural blooms—try to combine both for maximum benefit.
Common Mistakes to Avoid in Hummingbird Gardens
| Mistake | Why It’s a Problem | What To Do Instead |
|---|---|---|
| Overuse of chemicals | Reduces insect prey and risks toxin exposure to birds | Use natural pest control methods; avoid pesticides |
| Lack of plant variety | Short bloom period limits food supply | Plant a seasonal mix for extended nectar availability |
| Crowded feeders | Heightened aggression, disease risk | Space feeders and clean often |
| Ignoring protein sources | Chicks need insects for growth | Add native shrubs and perennials to attract insects |
Frequently Asked Questions: Attracting and Helping Hummingbirds
Q: How can I attract more hummingbirds to my yard?
A: Grow a variety of nectar-rich, tubular flowers, ensure a steady water source, avoid pesticides, and consider using several well-maintained sugar-water feeders.
Q: Are red flowers really the best choice?
A: Hummingbirds are particularly responsive to red and orange flowers, but they’ll also use other colors if nectar volume and accessibility are ideal. A mix of flower colors adds diversity and ensures blooms throughout the season.
Q: Should I feed hummingbirds year-round?
A: Feeders can help in migration or seasons of nectar scarcity but are not needed where natural food is abundant year-round. Remember to take down and clean feeders if local hummingbirds have left for migration to avoid attracting pests.
Q: Is it true hummingbirds won’t visit the same flower twice?
A: Not true—they visit flowers repeatedly, but will typically wait for nectar to refill before returning. This repeated visitation actually promotes pollination.
Q: Do male hummingbirds help care for the nest or young?
A: No. Female hummingbirds handle all nest-building, incubation, and chick-feeding responsibilities, while males focus on territory and mating opportunities.
Why Protecting Hummingbird Habitat Matters
With habitat loss and climate change reshaping natural flower availability, human gardens and feeders have become vital lifelines for hummingbirds. By selecting native, nectar-rich plants and maintaining safe, clean feeding stations, every gardener can support the needs of these dazzling birds. Even small urban gardens, when planted wisely and managed naturally, can become an indispensable oasis on a hummingbird’s migration route.
As you plan your landscape or simply hang a feeder by your window, remember: providing diverse blooms, clean water, and a safe, chemical-free environment will let you enjoy one of the most vivid and dynamic wildlife spectacles nature offers.
