The sight of a hummingbird inspires a natural desire to offer them a safe haven. Many bird enthusiasts consider installing a small house specifically for them, often stemming from observing other backyard species that readily adopt man-made structures for nesting. The question of whether hummingbirds use birdhouses, however, has a distinct answer based on their unique biology and nesting habits.
The Direct Answer About Birdhouses
Hummingbirds do not use traditional birdhouses, nest boxes, or any enclosed cavities for nesting or nightly roosting. They are fundamentally not cavity nesters, a biological classification that dictates their housing choice. Commercial products marketed as “hummingbird houses” are generally ineffective because they do not align with the bird’s instinctual need for an open-cup nest design. Providing a wooden box or similar structure will likely result in it being ignored.
What Hummingbirds Actually Use for Nests
The female hummingbird, who builds the nest alone, creates a marvel of miniature engineering that is far from a simple enclosed box. The structure is a tiny, compact, cup-shaped nest, often compared to the size of a golf ball or walnut. These nests are built on thin, often downward-sloping branches or in the fork of a branch, usually high off the ground, ranging from 10 to 90 feet in height.
Construction materials include soft plant fibers, bits of moss, and fine plant down. A defining feature is the use of spider silk, which functions as both glue and a flexible binder, allowing the nest to stretch and expand as the nestlings grow. The outside is then camouflaged with bits of lichen or moss, making the nest blend seamlessly with the branch. This intricate design provides a secure and highly concealed location for raising their young.
Why Hummingbirds Avoid Cavity Nests
The avoidance of enclosed spaces like birdhouses is a matter of survival tied to the hummingbird’s specific behaviors and physical limitations. Unlike birds that rely on a cavity’s protection, hummingbirds depend on camouflage, speed, and unobstructed visibility to evade potential threats. A traditional birdhouse limits the bird’s view of its surroundings, making it harder to spot predators like snakes, squirrels, or larger birds.
Their unique flight style, which involves rapid, precise movements, also necessitates a 360-degree clear flight path for instantaneous entry and exit. An entrance hole restricts this immediate escape route, which is a significant disadvantage for a creature that relies on its agility for safety. Furthermore, the small size of a hummingbird makes a typical birdhouse too large, which can complicate the regulation of temperature for their tiny eggs and hatchlings.
Attracting Hummingbirds Without Nest Boxes
To support local hummingbirds, focus on creating a rich habitat that provides the necessary food and natural nesting resources. Planting native flowering species with a preference for red or orange tubular blossoms, such as bee balm or honeysuckle, provides the high-calorie nectar they require. A continuous food supply from various blooms ensures they have fuel for their high metabolism throughout the nesting season.
Providing an appropriate water source is also helpful, as hummingbirds prefer to bathe by flying through a fine mist or spray rather than using a still birdbath. Leave natural nesting materials available by not removing all spiderwebs from your garden, as this silk is a primary component of their nest structure. You can also offer soft plant fibers from fuzzy-leafed plants like lamb’s ear or catkin-bearing trees.
If using a feeder, maintain a simple solution of one part white sugar to four parts water, and avoid using artificial dyes or sweeteners. Feeders must be cleaned every few days, especially in warmer temperatures, to prevent the growth of mold or fermentation. By cultivating a garden rich in natural resources, you provide the conditions that encourage a female hummingbird to nest nearby.
