How Big Are Hummingbird Eggs?

How Big Are Hummingbird Egg

During my ornithological research, I was once gifted with the sight of a hummingbird egg, no larger than a jelly bean nestled within a thimble-sized nest. My experience, observing these wonders, deepened my reverence for nature’s intricacies.

As an expert in avian biology, I believe that these eggs, though tiny, tell a story of survival and delicate balance. The mother’s meticulous nest construction, barely wider than a coin, highlighted the precision of life’s grand design.

This encounter with such a minuscule marvel not only broadened my understanding but also connected me to the fragile beauty of life’s tapestry.

Key Takeaways

  • Hummingbird eggs are incredibly small, ranging from 0.5 to 0.8 inches in length.
  • The Bee Hummingbird’s egg is even smaller, barely the size of a coffee bean.
  • Hummingbirds typically lay one to three eggs per year, with some species breeding multiple times annually.
  • Hummingbird nests are the smallest in the bird world and are constructed using materials like spider silk and plant fibers.

Hummingbird Egg Dimensions

When considering the diminutive size of hummingbird eggs, it’s notable that they typically range from 0.5 to 0.8 inches in length, akin to small jelly beans, with the Bee Hummingbird’s egg barely reaching the size of a coffee bean.

Female hummingbirds lay their eggs with meticulous care, producing tiny capsules that encapsulate the next generation. These Tiny Eggs, especially those of the Bee Hummingbird—the smallest bird known—are remarkably minuscule.

A Ruby-throated Hummingbird’s egg, for example, tips the scales at an almost negligible half a gram. In contrast, some hummingbird species’ eggs can weigh as little as 0.05 grams.

This illustrates just how big hummingbird eggs are: they’re not big at all, but rather exquisitely small marvels of avian reproduction.

Nesting Habits and Timing

Having explored the remarkable size of hummingbird eggs, let’s now examine their nesting habits and the timing of their breeding cycles, which are as intricate and varied as the diminutive eggs themselves.

Most hummingbirds lay eggs one to three times per year. Non-migratory species may breed several times annually, while Ruby-throated Hummingbirds typically have one brood but can lay more if a nest is destroyed.

Each year, hummingbirds build new nests, often opting for different trees or bushes than the previous season.

The breeding and egg-laying dates aren’t uniform among species. Hummingbirds nest with small clutches, usually laying two eggs, but ranging from one to three.

You can expect to find hummingbird eggs between March and June, depending on the species’ specific breeding timetable.

Egg Development and Hatching

Within the delicate confines of their intricately constructed nests, hummingbird eggs undergo a rapid and efficient development process, typically hatching within 15 to 18 days after being laid. You may wonder, how many eggs do hummingbirds lay? Most often, two eggs are deposited, although clutches can range from one to three. Here’s what happens after hummingbird eggs are laid:

Incubation15-18 days
Fledging18-28 days after hatching

Upon hatching, the chicks, with their eyes closed, are entirely dependent on their mother. Long does it take before these tiny creatures leave the nest, but within three to four weeks, they are ready to take their first flight. The Ruby-throated Hummingbird, among others, showcases this remarkable egg development and hatching process.

Protecting and Spotting Eggs

To ensure the survival of their delicate offspring, hummingbirds meticulously construct their nests, which are the smallest in the bird world, using materials such as spider silk to provide strength and flexibility. These tiny hummingbird nests are often festooned with lichen and plant fibers, enhancing their camouflage. When you see a hummingbird, it’s a glimpse into a world of intricate survival strategies.

  • Build their nests: Ruby-throated Hummingbirds, for instance, weave together materials that allow their tiny abodes to expand as the hummingbird eggs grow.
  • Protecting and spotting eggs: Their minuscule size means that spotting eggs can be a challenge, but it also necessitates proactive measures to safeguard them from threats.
  • Conservation efforts: Supporting groups like the American Bird Conservancy helps protect hummingbird eggs and the environments they depend on.

Frequently Asked Questions

What Size Are Hummingbirds Eggs?

You’re asking about the dimensions of hummingbird eggs—they’re tiny, akin to jelly beans, typically under half an inch long, and weigh a mere half gram, which is quite large for their body size.

What Does a Hummingbird Egg Look Like?

You’d notice hummingbird eggs are dull white, ovoid, and patternless, aiding in camouflage. They’re proportionally large for the bird but laid in small clutches, usually one to three without noticeable coloration or markings.

What Time of the Year Do Hummingbirds Lay Their Eggs?

You’ll find hummingbirds lay their eggs primarily in the spring and summer when conditions are ripe for raising their young, though tropical species may breed multiple times throughout the year.

How Big Is a Newly Hatched Hummingbird?

A newly hatched hummingbird is minuscule, about the size of a navy bean, weighing less than a dime and barely larger than its own eggshell from which it’s just emerged.


In conclusion, you’ll find hummingbird eggs to be astonishingly tiny, akin to jelly beans, with sizes ranging from coffee bean to penny length. Weighing less than half a gram, these ovoid gems are a dull white, blending seamlessly into their environment.

Typically, a hummingbird lays a pair, timing and nurturing them with precision. Spotting these miniature wonders demands keen eyes, as they’re masterfully concealed within their nests, a testament to the delicate intricacies of nature’s design.
