Anna’s hummingbirds (Calypte anna) typically build their nests in trees or shrubs, often in areas with dense foliage, at heights ranging from 6 to 20 feet above the ground.
Anna’s hummingbirds are native to the western coastal regions of North America, from Alaska to Baja California.
These birds are known for their strong territorial instincts and will defend their nesting sites vigorously.
They choose nesting locations that provide adequate cover from predators and weather, as well as a reliable food source nearby.
Anna’s hummingbirds are known for their intricate nest-building skills, often using spider silk to create a flexible and secure structure.
The nests are small and cup-shaped, built with a combination of plant material, lichen, and feathers.
The female bird is responsible for constructing the nest, which usually takes about one to two weeks to complete.
Once the nest is ready, the female will lay one to three eggs, which she will incubate for approximately 16 days before the chicks hatch.

Nesting Materials And Design
Types Of Materials Used To Construct Anna’S Hummingbird Nests
Anna’s hummingbirds are small birds, so it’s no surprise that their nests are tiny too.
Here’s a rundown of the materials they use to construct their nests:
- Lichens, mosses, and small leaves create the base of the nest. These materials are woven together using spider silk, which acts as a strong adhesive.
- The top layer of the nest is made of soft plant fibers, feathers, and hair.
As these hummingbirds build their nests in a wide range of areas, suitable nesting materials can vary. They’re known to use soft, insulating materials that can hold additional warmth and moisture, insulating the eggs from the cold.
Unique Design Features Of Anna’S Hummingbird Nests
Anna’s hummingbirds build intricate nests, varying slightly depending on where they’ve constructed them.
Here are some standout design features:
- Hinged lid design: These birds create an entrance at the top of their nests to keep their young safe from predators. A hinged lid of sorts allows the mother bird to quickly and easily access the nest beneath her.
- Stretchy walls: Hummingbirds need to be able to stretch their nest to accommodate their growing young. The spider silk used in the construction of the nest enables it to easily expand.
- Cup shape: A cup-shaped nest is necessary to keep the eggs in place, safe from harm. The lichen, moss, and spider silk utilized in the nest’s construction provide a snug, secure fit for the newly laid eggs.
Nesting Season And Timing
Where Do Anna’S Hummingbirds Nest: Nesting Season And Timing
Spring is the perfect season for birdwatchers, as birds are actively looking for a place to nest. Anna’s hummingbirds are one of the many bird species that start their nesting season during this time, with timing playing a crucial role in how they behave.
Here’s a closer look at the nesting season of anna’s hummingbirds and how timing affects their nesting behavior.
Overview Of The Nesting Season For Anna’S Hummingbirds:
- Anna’s hummingbirds usually start nesting in late winter or early spring, with the peak nesting season ending by mid-summer.
- These birds are known for building their nests using a variety of materials, including plant down, feathers, and spider webs, and they often choose high perches, such as tree branches or man-made structures, to nest.
- During the nesting season, female anna’s hummingbirds will lay up to four eggs, and both male and female will take turns incubating the eggs and feeding the chicks once they hatch.
Discussion Of How Timing Affects Nesting Behavior:
- Anna’s hummingbirds typically follow a set timing for nesting, which is influenced by daylight hours and weather conditions. Longer daylight hours trigger breeding behavior, and milder temperatures provide better nesting conditions.
- The timing of a hummingbird’s nesting season can also impact its breeding success. Early-season nesting pairs may face fewer predators and more abundant resources, while later nesting pairs may have a harder time finding enough food for their young and protecting them from predators.
- Climate change can also influence the timing of the nesting season for anna’s hummingbirds, as warmer spring temperatures can cause earlier onset of breeding behavior. However, changes in timing can have negative consequences for both nesting success and survival.
Overall, the nesting behavior of anna’s hummingbirds is a complex process that is heavily influenced by timing.
By understanding the nesting season and how it affects hummingbirds, birdwatchers can gain a deeper appreciation for these fascinating creatures’ reproductive habits.
