Ruby-throated hummingbirds are highly selective when it comes to the flowers they visit. They prefer flowers with tubular shapes and vibrant, often red or orange, colors. Some favorite nectar sources include trumpet vine, bee balm, and red or orange salvias.
They return to these blooms repeatedly, establishing feeding territories and defending them vigorously against intruders.
The Need for More than Nectar
While nectar provides the sugars crucial for their high-energy activities, it lacks the essential proteins, vitamins, and minerals necessary for a balanced diet.
To meet these nutritional needs, ruby-throated hummingbirds also incorporate other food sources into their menu:
Insects
Insects are an excellent source of protein for hummingbirds. These tiny birds are known to catch small insects, such as flies, gnats, and mosquitoes, by darting out from their perches. These insects provide the necessary protein for growth, maintenance, and reproduction.
Hummingbirds also feed on spiders, which are rich in protein. They may pluck spiders from their webs or capture them in mid-air.
Tree Sap
Ruby-throated hummingbirds have been observed tapping into sap wells created by sapsuckers, a type of woodpecker. This sap provides essential minerals and nutrients missing from their nectar-based diet.
Feeding Strategies
To maintain their diet and energy levels, ruby-throated hummingbirds have developed various feeding strategies:
Territorial Behavior
These birds establish and fiercely defend feeding territories, ensuring a reliable supply of nectar. The defense of these territories involves rapid chases, aerial displays, and vocalizations.
Frequency of Feeding
Ruby-throated hummingbirds have fast metabolisms, which necessitate frequent feeding. They visit flowers, and feeders, or catch insects throughout the day, often every 10 to 15 minutes.
Migration and Foraging
During their impressive migrations, ruby-throated hummingbirds rely on nectar-rich flowers as a primary food source. They strategically time their migrations to coincide with the blooming of specific flowers along their routes.
Torpor
To conserve energy during the night or when food sources are scarce, ruby-throated hummingbirds enter a state called torpor. In torpor, their metabolic rate drops significantly, enabling them to survive until better foraging conditions arise.
Conservation and Gardening
Understanding the dietary habits of ruby-throated hummingbirds is essential for their conservation.
As human activities, habitat loss, and climate change impact their food sources, it is crucial to ensure the availability of nectar-rich plants and a reduction in pesticide use.
By planting hummingbird-friendly flowers, providing nectar feeders, and maintaining natural habitats, we can support these incredible birds.
