Every spring, the United States and Canada are graced by the arrival of hummingbirds migrating northward to establish nests for their soon-to-be-born offspring. These incredible little travelers make their long journey from Mexico and South America, seeking a cooler and more suitable climate where they can raise their families. The decision of where to build their nests is crucial, as the survival of their young depends on it. They need a safe, sheltered spot that provides access to nectar and protection from predators. But finding the perfect location is only part of the challenge. Once they’ve chosen their ideal spot, the real task begins: constructing a nest. For a pregnant hummingbird, this delicate and demanding task becomes even more difficult, requiring extraordinary skill, precision, and energy to create a secure and comfortable home for her future family.

Protection from weather and heat in nest location.
When a female hummingbird is selecting the ideal site for her nest, two priorities take precedence: maintaining a suitable temperature and ensuring protection from the elements. Above all, the mother must ensure that the temperature remains below 96 degrees Fahrenheit, as any higher could result in the embryos being overheated and ultimately destroyed. This need for temperature control is why higher altitudes are particularly attractive to nesting hummingbirds, as the cooler environment helps keep the conditions within the safe range. Additionally, areas near bodies of water are often favored, as the natural surroundings can provide a cooling effect.
How they beat the heat
However, some hummingbird species, like the Ruby-throats, have adapted to “beat the heat” even at lower elevations. These birds seek refuge in the canopies of broad-leafed trees, where temperatures are typically about 6 degrees Fahrenheit cooler than in the open air. This cooler shelter not only prevents overheating but also allows the hummingbirds to thrive in warmer areas that would otherwise be inhospitable. These trees also serve as a shield from harsh weather elements, particularly wind, which can be particularly dangerous for young birds and delicate nests.
Shelter from the wind
Protection from high winds is a critical factor in a hummingbird’s choice of nesting site. Strong gusts can easily damage the nest or cause the eggs to roll out, which may lead to the loss of the eggs or make them vulnerable to predators. The mother must therefore be diligent in choosing a location where her nest will remain sheltered from such hazards. All of these considerations—temperature, protection from wind, and shelter from other adverse weather—play a vital role in the selection process. Once the mother hummingbird has found the ideal spot, the next step is to begin building her nest, where she will carefully create a safe haven for her future offspring.

Hummingbird Nest Construction: A Tiny Marvel of Nature
Hummingbirds are fascinating creatures. Their nests, though small, are wonders of craftsmanship. These tiny birds use a variety of natural materials to build their homes, creating intricate structures that are both delicate and strong. Let’s explore the process of hummingbird nest construction, step by step.
The Start of Nest Building
Building a nest is an instinctive task for female hummingbirds. It begins with a search for the perfect location. The bird looks for a safe, sheltered place, often in a tree or shrub. The spot needs to be hidden from predators but also in a good spot for access to food.
Selecting the Right Spot
The chosen location is critical for the survival of the nest. The female hummingbird looks for a place with plenty of natural cover. This can be a branch with dense leaves or even the underside of a small tree. Sometimes, they build nests near human homes, in garden trees or hanging baskets.
The location also needs to provide easy access to flowers and feeders. Hummingbirds eat frequently, so proximity to nectar sources is important.
The Construction Begins
Once the location is selected, the real work starts. The hummingbird begins gathering materials. She does this carefully, collecting tiny pieces from the environment.
Gathering Materials
Hummingbirds are resourceful. They collect natural materials such as:
- Soft plant down
- Spider silk
- Lichen
- Feathers
- Small twigs
The soft plant down comes from plants like dandelions, thistles, and cottonwoods. Spider silk is used because it is strong, flexible, and sticky. The hummingbird uses it to weave the nest together, securing the materials tightly. Lichen gives the nest its camouflaged, greenish appearance, helping it blend into the surrounding environment.
Building the Nest Structure
The female hummingbird begins by forming a small, cup-shaped structure. The nest is typically about 2-3 inches across and only 1 inch deep. She uses her beak to push the materials into place, shaping the structure carefully. The spider silk is used to hold the nest together. This flexible material allows the nest to expand as the young birds grow.
The outside of the nest is often covered in lichen, which not only camouflages it but also helps to protect it from the elements.
Adding the Inner Lining
Once the basic structure is in place, the hummingbird adds a soft lining to the inside of the nest. She uses the softest plant down, feathers, and even tiny cotton fibers. This soft, insulating material helps keep the eggs warm and provides comfort for the hatchlings.
The lining is carefully arranged to ensure warmth and protection. The female often adds and adjusts the lining throughout the nesting period, ensuring it remains soft and cozy for her eggs.
The Nest’s Durability
Despite its small size and delicate appearance, a hummingbird nest is remarkably strong. The materials, particularly the spider silk, give it flexibility and durability. The nest can withstand rain, wind, and even the occasional visit from predators. However, the hummingbird does not leave the nest unattended for long. She stays close, protecting her future offspring.
Laying the Eggs
Once the nest is complete, the female hummingbird lays her eggs. Usually, she lays two eggs, each about the size of a jellybean. The eggs are typically white and can be about the size of a small marble.
The female carefully places them in the nest and begins the incubation process. During this time, she sits on the eggs to keep them warm. Hummingbirds have high metabolic rates, and they need to stay warm to ensure successful hatching.
Incubation and Hatching
The female hummingbird will incubate the eggs for about 10-14 days, depending on the temperature. During this time, she must leave the nest briefly to feed and drink. However, she always returns quickly to keep the eggs warm.
Once the eggs hatch, the tiny chicks are blind and helpless. They are also completely dependent on their mother for warmth and food. The female feeds them by regurgitating nectar and small insects, which provides them with the necessary nutrition to grow.
The Chicks’ Growth
As the chicks grow, the nest continues to expand. The flexible spider silk allows the nest to stretch to accommodate the growing birds. The chicks grow quickly, and after about 3-4 weeks, they are ready to leave the nest.
Leaving the Nest
When the young hummingbirds are ready to fledge, they will leave the nest. The female hummingbird encourages this process by gradually reducing the amount of food she provides. This encourages the chicks to become more independent.
The young hummingbirds leave the nest, but they don’t fly far at first. They will stay near the area, learning to forage for nectar and insects. The mother may continue to care for them for a short time, but soon, they are fully independent.
The End of the Nest’s Life Cycle
Once the young birds have fledged and are on their own, the nest is no longer needed. It will begin to break down over time. The materials, such as lichen, will decay, and the spider silk will lose its strength. Eventually, the nest is gone, and the cycle is complete.
Conclusion
Hummingbird nest construction is an intricate and amazing process. The female hummingbird gathers materials, weaves the nest, and creates a home for her eggs. Though the nest is small and delicate, it is a marvel of natural engineering. From the careful choice of location to the final stage of leaving the nest, every step shows the bird’s incredible instincts and ability to adapt.
Hummingbird nests are a testament to the ingenuity of nature. These tiny creatures prove that even the smallest beings can create wonders. The next time you see a hummingbird, take a moment to appreciate the craftsmanship behind the home they’ve built.

The Male’s Brief Role in Nesting
During the nesting process of hummingbirds, the male plays a vital but short-lived role. His primary function is to fertilize the female, and once this task is complete, he is promptly sent away. While his brilliant, colorful feathers are a symbol of vitality and attractiveness, they also pose a significant risk. The vivid plumage that helps him attract a mate makes him highly visible to predators. Once the female is fertilized, she instinctively knows it’s time for him to leave, as his presence could jeopardize the safety of the nest.
The Female Takes Charge
With the departure of the male, the female assumes full responsibility for the nest. This marks the beginning of her most critical duties, and she tackles them with exceptional intelligence and dedication. She now must protect and care for the eggs or young chicks, using all of her resourcefulness to keep them safe from any threats. Unlike many other species, hummingbirds do not rely on the male for assistance after fertilization. The female is entirely on her own during this final stage of nesting.
Protection and Resourcefulness
The female hummingbird demonstrates remarkable resourcefulness and intelligence in safeguarding her nest. Hummingbirds are known for their quick reflexes and sharp minds, and the female uses these traits to defend her territory. She may create distractions to lead predators away or use her speed and agility to fend off any threats. Her small size allows her to maneuver quickly, making it difficult for predators to catch her or get close to the nest.
Balancing Nurturing and Defense
One of the most impressive aspects of the female hummingbird’s nesting behavior is her ability to balance the nurturing of her young with the defense of the nest. She must remain vigilant to ensure her eggs or chicks are safe, while also maintaining her energy and focus to protect them from larger animals. Whether by intimidating intruders or using her aerial agility to escape danger, the female hummingbird’s defense tactics are as strategic as they are effective.
Masters of Survival
Though they are small and delicate in appearance, hummingbirds are incredibly resilient and resourceful when it comes to survival. The female’s role in protecting the nest showcases not only her fierce determination but also her intelligence. She demonstrates the hummingbird’s ability to thrive in the face of adversity, ensuring that the next generation of these stunning creatures has the best chance of survival. In this way, hummingbirds are not just marvels of nature’s beauty but also masters of their environment.
