The Truth about Hummingbirds and the Color Red

Hummingbirds are some of the most fascinating creatures in nature. With their iridescent feathers and rapid wing beats, they capture the imagination of anyone lucky enough to see them up close. One common belief that has persisted over time is that hummingbirds are attracted to the color red. But is it really true? Let’s take a closer look at the relationship between hummingbirds and the color red, and uncover the science behind this popular belief.

Do Hummingbirds Actually Like Red?

While it’s widely believed that hummingbirds are drawn to red, the truth is a bit more nuanced. Hummingbirds are attracted to bright, vibrant colors, but it’s not just red that catches their attention. They are especially drawn to colors like orange, pink, and purple, which are common in many flowering plants they feed from.

However, red flowers often stand out to humans because of their high visibility, and many species of flowers that attract hummingbirds are naturally red. So, while red flowers are more likely to catch a hummingbird’s eye, it’s not solely the color red that draws them in, but rather the shape of the flower and the presence of nectar-rich blooms.

Why Are Hummingbirds Attracted to Colorful Flowers?

Hummingbirds have exceptional color vision, which is far superior to humans. They can see a wide spectrum of colors, including ultraviolet, which is invisible to us. Their keen eyesight helps them spot flowers that are rich in nectar. Colors like red, orange, and pink signal that a flower is likely to contain nectar, which is a primary food source for hummingbirds.

In nature, many red and orange flowers tend to be tube-shaped, which are ideal for hummingbirds because their long, specialized beaks can easily access the nectar. The bright color serves as a visual signal that these flowers are the perfect feeding stations.

The Role of Red in Hummingbird Feeders

If you’ve ever set up a hummingbird feeder in your yard, you may have noticed that many of them come with red accents or are entirely red. While the red color may not be essential, it can help attract hummingbirds. The bright red hue of feeders may simply mimic the flowers hummingbirds naturally seek out.

However, some research suggests that hummingbirds are more drawn to the shape and placement of feeders than the color itself. In fact, a study by Cornell Lab of Ornithology found that hummingbirds will visit a feeder just as readily if it’s clear, as long as it contains the right amount of nectar and is positioned correctly.

Is Red Food Dye Safe for Hummingbirds?

A common practice is to add red food coloring to homemade hummingbird nectar. However, experts strongly recommend against this. Red dye can be harmful to hummingbirds and may cause health issues, including digestive problems and even long-term harm.

The natural red color of flowers and feeders is enough to attract them. If you’re making your own nectar at home, stick to a simple mix of sugar water—4 parts water to 1 part sugar, boiled to dissolve the sugar, and cooled before use. There’s no need for artificial colors or additives.

How to Attract Hummingbirds to Your Garden

If you want to attract more hummingbirds to your garden, here are some tips:

1. Plant Nectar-Rich Flowers: Choose flowers that are bright, tubular, and rich in nectar. Favorites include beebalm, trumpet vine, fuchsia, salvia, and columbine.
2. Add a Hummingbird Feeder: Position a feeder in a sunny spot with no obstacles. Opt for feeders with bright red accents, or even natural-colored ones—just make sure they are cleaned regularly to prevent mold growth.
3. Provide a Water Source: Hummingbirds also like to bathe. Install a misting fountain or a shallow birdbath to keep them refreshed.
4. Create a Safe Space: Make sure your garden has plenty of hiding spots and perching areas for hummingbirds to rest between feedings.

Final Thoughts

While the color red may be appealing to hummingbirds, it is not the sole factor in attracting them. Their attraction to flowers is largely due to a combination of color, shape, and nectar availability. So, while red flowers and feeders may help, don’t forget to plant a variety of nectar-rich, brightly colored flowers and create an inviting environment to keep your garden buzzing with these tiny, magical birds.
