The ruby-throated hummingbird, a tiny jewel of the avian world, is a captivating creature that graces gardens across eastern North America. Known for its iridescent plumage and incredible agility, this hummingbird’s survival hinges on a readily available source of nectar. So, what flower truly captures the heart (or rather, the taste buds) of this miniature marvel? The answer, while seemingly simple, is nuanced and fascinating. It’s not just one single flower, but a collection of characteristics that make certain blossoms irresistible to these hovering dynamos.
Understanding Hummingbird Preferences: More Than Just Nectar
The ruby-throated hummingbird’s preference for specific flowers is driven by a complex interplay of factors, extending beyond mere sugar content. While nectar is undoubtedly the primary draw, other elements such as flower shape, color, scent, and accessibility play crucial roles in attracting these tiny birds.
The Sweetest Reward: Nectar Composition and Availability
Nectar, the sugary liquid produced by flowers, is the hummingbird’s primary energy source. Ruby-throated hummingbirds have a high metabolic rate, requiring them to consume large amounts of nectar throughout the day. The ideal nectar for a hummingbird isn’t just about sweetness; it’s about the sugar composition. Hummingbirds prefer nectar with a higher sucrose content, similar to the homemade nectar solutions many bird enthusiasts provide (typically a 4:1 water-to-sugar ratio).
The availability of nectar is equally important. Flowers that produce copious amounts of nectar are more likely to attract hummingbirds. The depth and shape of the flower’s corolla (the collective term for petals) influence accessibility. Hummingbirds have long, slender bills and tongues perfectly adapted for reaching nectar deep within tubular flowers.
A Visual Feast: The Allure of Color
Color plays a significant role in attracting hummingbirds. They are particularly drawn to the color red. This is because many insects, especially bees, cannot see red, so red flowers are often less visited by insects that might compete with the hummingbirds for nectar. While red is a powerful attractant, ruby-throated hummingbirds are also attracted to orange, pink, and purple flowers. The key is vibrancy and visibility against the surrounding foliage.
The Importance of Flower Shape and Size
The shape and size of a flower are crucial factors influencing a hummingbird’s ability to access the nectar. Tubular flowers, such as trumpet honeysuckle and salvia, are particularly well-suited for hummingbirds. The elongated shape allows the hummingbird to insert its bill and tongue deep into the flower to reach the nectar. Flowers with wide, open faces, while accessible to other pollinators, are less attractive to hummingbirds, as they may not offer a sufficient nectar reward for the effort expended.
The Role of Scent (or Lack Thereof)
Unlike many other pollinators, such as bees and butterflies, hummingbirds have a relatively poor sense of smell. Therefore, scent plays a less significant role in attracting them to flowers. While some hummingbird-attracting flowers may have a subtle fragrance, it is primarily the visual cues, particularly color, that draw them in.
Top Contenders: Flowers That Ruby-Throated Hummingbirds Love
Identifying a single “favorite” flower is challenging, as hummingbird preferences can vary depending on location, availability, and individual bird preferences. However, several flowers consistently rank high on the ruby-throated hummingbird’s list of preferred nectar sources.

Creating a Hummingbird Haven: Tips for Attracting Ruby-Throats
Attracting ruby-throated hummingbirds to your garden involves more than just planting a few flowers. Creating a hummingbird-friendly habitat requires careful planning and consideration of the birds’ needs.
Planting a Diversity of Flowers
To provide a continuous source of nectar throughout the growing season, plant a diversity of flowers that bloom at different times. This will ensure that hummingbirds have access to food from early spring to late fall. Consider planting early-blooming flowers, such as columbine and bleeding heart, to attract hummingbirds as soon as they arrive in the spring. Include mid-season bloomers, such as bee balm and salvia, to provide a consistent nectar source during the summer months. And don’t forget late-blooming flowers, such as cardinal flower and trumpet creeper, to sustain hummingbirds as they prepare for their fall migration.
Choosing Native Plants
Native plants are generally the best choice for attracting hummingbirds and other wildlife. Native plants are adapted to the local climate and soil conditions, making them easier to grow and maintain. They also provide a valuable food source for native insects, which in turn support a healthy ecosystem. When choosing plants for your hummingbird garden, prioritize native species whenever possible.
Providing Water and Shelter
In addition to nectar, hummingbirds also need access to fresh water for drinking and bathing. A shallow birdbath or a gentle misting system can provide a refreshing source of water. Hummingbirds also need shelter from predators and harsh weather. Trees and shrubs can provide cover and nesting sites.
Avoiding Pesticides
Pesticides can be harmful to hummingbirds and other beneficial insects. Avoid using pesticides in your garden, or choose organic alternatives. Encourage natural pest control by attracting beneficial insects, such as ladybugs and lacewings.
Maintaining Hummingbird Feeders (Responsibly)
While natural nectar sources are ideal, hummingbird feeders can supplement their diet, especially during times when flowers are scarce. It is crucial to maintain feeders properly by cleaning them regularly (at least twice a week, or more frequently in hot weather) to prevent the growth of harmful bacteria and mold. Use a simple solution of 4 parts water to 1 part granulated white sugar (no dyes or additives). Avoid honey, as it can promote fungal growth.
Beyond the Garden: Factors Affecting Hummingbird Foraging
The flowers that a ruby-throated hummingbird favors aren’t just dependent on the blossoms in your backyard. Larger environmental factors and the hummingbird’s own learning contribute to its foraging behavior.
Competition for Nectar
Hummingbirds compete with other nectar-feeding animals, such as bees, butterflies, and even other hummingbirds, for access to floral resources. This competition can influence which flowers a hummingbird chooses to visit. In areas with high competition, hummingbirds may be more likely to forage on flowers that are less attractive to other pollinators.
Habitat Fragmentation and Loss
Habitat fragmentation and loss can reduce the availability of suitable foraging habitat for hummingbirds. As natural areas are converted to urban or agricultural land, the number of flowers available to hummingbirds declines. This can lead to increased competition and reduced hummingbird populations.
Climate Change
Climate change can also affect hummingbird foraging behavior. Changes in temperature and precipitation patterns can alter the timing of flowering, making it difficult for hummingbirds to find nectar at the right time. Climate change can also lead to shifts in the distribution of plants, potentially reducing the availability of suitable foraging habitat in some areas.
Learned Behavior and Individual Preferences
Individual hummingbirds can develop preferences for certain flowers based on their past experiences. A hummingbird that has had a positive experience feeding on a particular flower may be more likely to visit that flower again in the future. This learned behavior can influence which flowers a hummingbird chooses to forage on.
Conclusion: A Symphony of Nectar and Beauty
The ruby-throated hummingbird’s favorite flower is not a single entity, but rather a collection of qualities that make a flower an irresistible nectar source. While red, tubular flowers with abundant nectar are consistently favored, factors like native status, blooming period, and overall habitat quality contribute to the bird’s foraging choices. By understanding these preferences and creating hummingbird-friendly gardens, we can play a vital role in supporting these amazing creatures and ensuring their continued presence in our landscapes. The vibrant flash of a ruby-throated hummingbird visiting a flower is a testament to the intricate relationship between plants and animals, a relationship worth celebrating and protecting.
What characteristics make a flower particularly attractive to Ruby-Throated Hummingbirds?
Ruby-Throated Hummingbirds are drawn to flowers with specific qualities tailored to their feeding habits. They prefer flowers that are tubular in shape, allowing them to easily insert their long beaks and tongues to reach the nectar. The color red is a major attractant, although they also visit orange, yellow, and pink blooms. These colors are visually prominent in the hummingbird’s visual spectrum.
Additionally, these hummingbirds favor flowers that produce copious amounts of nectar, offering a worthwhile energy reward for their efforts. Flowers with little or no scent are also favored, as hummingbirds rely more on sight than smell to locate their food sources. A strong flower structure that can support the bird’s weight while feeding is also beneficial, allowing for easier access to the nectar.
Why is the color red so attractive to Ruby-Throated Hummingbirds?
The strong attraction to the color red is primarily due to evolutionary factors and the hummingbird’s visual system. Unlike insects like bees, hummingbirds possess excellent color vision, particularly within the red spectrum. This heightened sensitivity allows them to easily locate red flowers from a distance, making them a valuable food source.
Furthermore, many red flowers are less appealing to insects, reducing competition for nectar. This means that red flowers often provide a more reliable and abundant source of food for hummingbirds. Over time, this has resulted in a strong association between red flowers and nectar-rich meals, solidifying the color red as a primary attractant.
Are there any native North American flowers that Ruby-Throated Hummingbirds particularly favor?
Yes, several native North American flowers are highly favored by Ruby-Throated Hummingbirds, offering both nectar and habitat benefits. Trumpet Honeysuckle (Lonicera sempervirens) is a particularly attractive vine, providing a reliable nectar source with its bright red, tubular flowers. Similarly, Bee Balm (Monarda didyma), also known as Oswego Tea, is another native favorite, boasting vibrant red blossoms and attracting pollinators in addition to hummingbirds.
Cardinal Flower (Lobelia cardinalis) is another excellent choice, featuring intensely red, upright spikes of tubular flowers that are perfectly suited for hummingbird beaks. These native options are not only beneficial for hummingbirds but also contribute to local biodiversity and require less maintenance than non-native alternatives.
Do Ruby-Throated Hummingbirds exclusively feed on flowers?
While nectar from flowers is a significant component of their diet, Ruby-Throated Hummingbirds do not exclusively feed on it. They also require protein and other nutrients, which they obtain by consuming small insects and spiders. These insects are crucial, especially during breeding season when the hummingbirds need to feed their rapidly growing chicks.
Hummingbirds often catch insects on the wing or glean them from flowers, leaves, and tree bark. They may even pick insects out of spiderwebs. This insect consumption provides essential amino acids and other building blocks that nectar alone cannot supply, making it a vital part of their overall nutritional intake.
How can I create a garden that attracts Ruby-Throated Hummingbirds?
Creating a hummingbird-friendly garden involves selecting plants with specific characteristics that appeal to these birds. Focus on planting a variety of tubular-shaped flowers, especially those in shades of red, orange, and pink. Choose native species whenever possible, as these are often best adapted to the local climate and provide the most benefit to local wildlife.
Arrange your garden with a succession of blooming plants throughout the growing season to ensure a continuous food supply. Avoid using pesticides, as these can harm hummingbirds and eliminate their insect prey. Providing a source of fresh water, such as a shallow birdbath or a gentle mister, can also attract hummingbirds to your garden.
Is there a specific time of day when Ruby-Throated Hummingbirds are most active at flowers?
Ruby-Throated Hummingbirds exhibit a fairly consistent level of activity throughout the daylight hours, but their peak feeding times often correlate with periods of increased energy demand. Early morning and late afternoon are generally the times when hummingbirds are most actively feeding. This is when they need to replenish energy reserves depleted overnight or to build up energy for the evening.
The specific timing can also depend on weather conditions and flower availability. On cooler or overcast days, hummingbirds may feed more consistently throughout the day to maintain their body temperature. Conversely, during hot midday hours, they might seek shade and conserve energy, resuming active feeding in the cooler late afternoon.
What should I do if I find a Ruby-Throated Hummingbird in distress near flowers in my garden?
If you encounter a Ruby-Throated Hummingbird that appears injured or distressed near your flowers, approach the situation with caution and observation. First, carefully assess the bird’s condition.
