Have you ever wondered what fuels the energetic flits and flights of those captivating hummingbirds in your backyard? It’s not just the sugary sweetness of nectar!
Hummingbirds can fly long distances in search of food. Some species fly thousands of miles during migration, with some rufous hummingbirds flying up to 2,000 miles throughout their migration ¹.
From tiny insects to the surprising bite of fruit, hummingbirds have a diverse palette that supports their high-speed lifestyle. Here’s eight of their favorite foods.
1. Nectar: The Sweet Starter
Hummingbirds are synonymous with nectar, nature’s energy drink. With tongues equipped with fringed, hair-like projections known as papillae, these birds are adept at sipping nectar from a spectrum of flowers. They favor long, tube-shaped blossoms but won’t shy away from short, shallow ones. This liquid diet is supplemented by almost any flower imaginable, from daisies to trumpets.
Considering their high metabolism, nectar provides the quick sugar fix hummingbirds need to keep zooming. Studies have shown that these birds can visit hundreds of flowers in a single day, ensuring they get enough calories to sustain their energy levels (ref).
2. Insects: Protein Packs
While nectar offers energy, protein is crucial for growth and health. Hummingbirds snack on an assortment of insects, including small flies, spiders, and caterpillars. They can catch these mid-flight or pluck them from vegetation, showcasing their versatile feeding tactics.
Their pursuit of insects provides essential nutrients not found in nectar. Research indicates the crucial role that this protein source plays in their diet, especially for the growth of young hummingbirds (ref).
3. Pollen: An Accidental Snack
Direct consumption of pollen is not a hummingbird’s goal, but they inevitably ingest it while feasting on nectar. Though it’s a minor part of their diet, the pollen offers a supplementary protein boost.
Given their role in pollination, hummingbirds moving from flower to flower inadvertently pick up and consume pollen grains. This serendipitous intake contributes to their nutritional intake, albeit modestly.
4. Tree Sap: The Backup Plan
Tree sap becomes a sought-after resource when nectar is limited. Hummingbirds use the holes created by sapsuckers (woodpeckers) to access this sticky treat. This sap provides a similar sugar concentration to nectar, making it an excellent alternative.
This adaptation highlights the hummingbird’s resourcefulness, ensuring they have access to energy sources throughout varying conditions and seasons.
5. Fruits: Juicy Extras
Occasionally, hummingbirds might indulge in the juices of ripe fruits. Berries, apples, and even oranges can attract these birds, especially if the fruit is cut open to expose the sweet interior.
While not a staple in their diet, fruit offers a refreshing change and additional nutrients. This behavior emphasizes their opportunistic and adaptive feeding habits.
6. Ashes & Sand: The Mineral Mix
In an unexpected twist, hummingbirds have been spotted consuming ashes and sand in small quantities (ref). This behavior is believed to provide essential minerals and salts, though the exact benefits remain under study.
This unique aspect of their diet puzzles many and signifies there’s still much to learn about these fascinating birds.
7. Opportunistic Dining
Apart from their usual diet, hummingbirds have been known to eat spiders, spider eggs, and pollen grains adhering to their bodies. This flexibility ensures they maximize their nutritional intake from available resources.
Their willingness to consume a broad range of foods underlines the adaptability and survival skills of hummingbirds in various environments.
8. Feeding Frequency: The Need for Speed
To support their fast-paced lifestyle, hummingbirds consume up to half their body weight in food daily. They may visit food sources every 10-15 minutes, a testament to their incredibly high metabolism (ref).
This rapid rate of feeding is necessary to maintain their energy levels, allowing them to perform their signature acrobatic flights.
Hummingbirds’ diets are as vibrant and varied as the birds themselves. Their eating habits reflect the perfect balance between taking from and giving back to nature, reminding us of the beautifully interconnected web of life.
