Witnessing the hummingbird’s courtship display is wonderful. Still, this might leave you wondering “when do hummingbirds lay eggs.” The answer depends on the species. Most hummingbirds will generally lay eggs from March to July, while some will nest from February to June.

Here, you’ll learn more about hummingbird nesting, incubation, and babies. Keep reading to find some fun facts as well.

When Do Hummingbirds Lay Eggs?

Once the mating ritual is finished, the female hummingbird will proceed to the nest. Most North American hummingbirds usually lay eggs from March to July, depending on how far up north they’re located. 

Besides the time of year, the nesting season depends on the species of hummingbirds. For example, a female Anna’s hummingbird may start building a nest as early as December.

Allen’s hummingbird may lay their eggs from November to February the following year while Costa’s Hummingbird lay their eggs from February to June. Ruby-throated hummingbirds will spend winters in Mexico and Central America and nest from March to July.

Additionally, most hummingbird species will raise 1 to 2 broods per nesting season. On rare occasions, hummingbirds lay eggs 3 times a year.

All You Should Know About Hummingbirds’ Nests

Even though males arrive at the breeding grounds before females, they won’t partake in nest building. As soon as the mating ritual is done, females will proceed to the nest, and males will move on to looking for another female.

Surprisingly, you won’t see hummingbirds making a nest in nest boxes, tree cavities, or other hidden spots. Instead, they’ll build new nests in sheltered trees, forked branches, or shrubs. Most hummingbird moms will use many different nesting materials, such as:

  • Spider webs
  • Lichens
  • Other plant materials

These ensure that the nest is secure and camouflaged. Additionally, spider webs make the nest stretchy, so it can fit the hatchlings as they grow.

How Do You Find a Hummingbird Nest?

The hummingbird nest is so well camouflaged that you might have difficulty spotting it. Mother hummingbirds will use lichens and moss during nest-building to hide the nests, so they might look like just another tree knot, perfectly matching the environment.

However, some birdwatchers will know when the mother is getting ready to nest and will follow the whole process, so they’ll manage to locate the nest. You can do this too, by carefully observing the hummingbird’s behavior.

Start by looking for courtship dives. During those, the male hummingbird will impress the female, which will help you discover which bird you should follow. The mating ritual happens after the female accepts the male.

The mating usually lasts for about 5 seconds. After that, you might spot the female working on her nest. However, know that approaching the nest will likely disturb her and prevent her from taking care of the baby birds.

If the nest looks undisturbed, it’s best to leave it alone. If you believe the nestlings are endangered, contact a wildlife sanctuary for advice.

Hummingbirds may also nest in your shed, garage, or even among potted plants. For example, the Rufous hummingbird is known for building nests on hanging ropes.

If you notice a nest in these parts of your yard, leave it be. Don’t move the potted plants or try to get the nest to the nearest tree. The female hummingbird will lose track of her babies.

Also, note that hummingbirds tend to return to the same area to nest each year. They may not reuse the nests, but will likely make a new one somewhere nearby, which is excellent if you want to observe them. Remember, it’s against the law to touch, move, or interfere with active nests in the US.

What Is the Size of Hummingbird Eggs?

Hummingbirds have such tiny eggs that they’re typically compared to jellybeans or coffee beans. To give you another perspective — the hummingbird nest looks like a walnut shell with two small tic tac breath mints.

The egg size barely differs among various hummingbirds. For example, Ruby-throated, Rufous, and Anna’s hummingbird’s eggs are about 0.55 inches (1.3 cm) long and 0.3 inches (0.8 cm) wide.

How Do Hummingbirds Protect Their Eggs?

Female hummingbirds will be meticulous in protecting their egg-laying site. Camouflaging is the first layer of protection, but if that fails, mommy hummingbird will get enringed.

If any predators come nearby, she’ll do her best to defend her eggs and nest. Cats, jays, other hummingbirds, and crows are common enemies, which female hummingbirds will try to chase off by aggressive flying.

How Do Baby Hummingbirds Grow and Develop?

The life cycle of hummingbird chicks is quite interesting. Once the mother hummingbird builds a nest, she will proceed to incubate her eggs for around 15 to 18 days when they’ll hatch. Baby hummingbirds will get born naked with their eyes closed.

Their beaks are short, and they’re tiny and fragile. Still, they’ll grow fast, and it’s now the mom’s responsibility to feed them all day long. Babies will eat nectar from flowering plants and regurgitated insects.

At around the 20th to 23rd day, hummingbird chicks will fledge from the nest and fly away. Still, some hummingbird mom will feed their babies outside the nest for a few more days.

How Long Does It Take for Hummingbird Eggs to Hatch?

Once the nest is built, the female hummingbird will lay the first egg. Then, she’ll take a break—sometimes for the whole day—before she lays the second egg. Now, the incubation period can start.

Different species of hummingbirds have different incubation periods, but generally, it can last from 14 to 21 days until the eggs hatch. Climate also affects how fast the eggs hatch—hummingbirds in the colder regions will reduce their nesting activity.

Why Do You Never See Baby Hummingbirds?

One of the primary reasons you won’t see young hummingbirds is the appearance of the nest. If you haven’t followed up with the female hummingbird from the moment she picked a spot for nesting, you’ll have a hard time locating the babies.

Plus, the birds might think your yard is unsafe or lacks good nesting conditions. They may still come to your hummingbird feeders; they just won’t nest in their proximity.

How Long Does a Baby Hummingbird Stay in the Nest?

When baby hummingbirds hatch, they usually stay in the nest for 18 to 28 days. After one week from hatching, they’ll grow fuzzy feathers. By week two, they’ll start growing real feathers.

Then, they’ll test their wings for flight. In three weeks, they’ll proceed to test out their wings more and more and start looking like real hummingbirds. In the next few days, they’ll fly away, never to return.

What Is the Best Time to See Baby Hummingbirds?

Hummingbird chicks are usually born in late spring or early summer. Surprisingly, even though the female hummingbird lays eggs separately, she’ll still control when they hatch by incubating both eggs equally.

If everything goes well, you’ll likely see the babies once they learn to fly. However, they might sometimes fall out of the nest, so you’ll want to be on the lookout and react if that happens.
