Calliope Hummingbird Life History

The Calliope Hummingbird (Selasphorus calliope) enchants bird enthusiasts with its diminutive size and vibrant plumage. 

Understanding the life history of this captivating species provides valuable insights into its behavior, reproduction, and conservation needs. 

From feeding habits to nesting preferences, the Calliope Hummingbird’s life history unfolds as a fascinating journey through its unique adaptations and challenges.



The primary source of sustenance for Calliope Hummingbirds is nectar from a variety of wildflowers. 

Their specialized bills and long, extendable, tube-like tongues allow them to efficiently extract nectar from blossoms. 

In addition to nectar, they also consume small insects and spiders, providing essential protein to supplement their diet. 

Remarkably, Calliopes are known for their aerial acrobatics, capturing insects mid-flight during their foraging expeditions.


Calliope Hummingbirds exhibit a preference for high-altitude habitats, often inhabiting mountainous regions and open woodlands. 

They are commonly found in meadows adorned with an abundance of wildflowers, providing both nesting materials and a steady supply of nectar. 

These agile birds have adapted to a diverse range of elevations, from subalpine zones to lower mountainous areas.

Range Map

The Calliope Hummingbird’s range spans the western part of North America, with breeding grounds extending from southern Alaska through the Rocky Mountains and into northern Mexico. 

Utilizing a range map aids birdwatchers and conservationists in tracking their migratory patterns and understanding the geographical areas crucial for their survival.



Calliope Hummingbirds are meticulous nest builders. Females construct small, cup-shaped nests using plant fibers, spider silk, and downy materials. 

Nests are often situated on horizontal branches, providing stability and camouflage. 

Their choice of nesting sites is strategic, usually near reliable food sources and within their preferred elevational range.

Here’s a table summarizing the nesting details of the Calliope Hummingbird:

Nesting Details Facts
Clutch Size Usually consists of 2 pea-sized eggs
Number of Broods Typically raises 1 brood per breeding season
Egg Length Approximately 0.5 inches (1.27 cm)
Egg Width Around 0.3 inches (0.76 cm)
Incubation Period Approximately 15-18 days
Nestling Period Approximately 20-22 days
Egg Description Small and white, resembling miniature jelly beans
Nest Construction Cup-shaped, built with plant fibers, spider silk, and downy materials
Nesting Site Positioned on horizontal branches, often in proximity to reliable food sources

The breeding season sees an elaborate courtship display by males to attract potential mates. The vibrant magenta-red gorget and the intricate aerial displays play pivotal roles in securing a mate. 

After successful courtship, females lay two pea-sized eggs, which they incubate for about two weeks. The offspring fledge within three weeks, rapidly becoming independent and embarking on their foraging journeys.

Diseases and Treatment

While hummingbirds, including Calliopes, are generally hardy, they are susceptible to diseases such as avian pox and parasitic infections. 

Monitoring bird feeders for signs of sick birds, practicing regular cleaning, and providing fresh nectar are essential steps in preventing disease transmission. 

In cases of illness, consulting with wildlife rehabilitators or veterinarians specializing in avian care can aid in effective treatment and rehabilitation.



Despite their resilience, Calliope Hummingbirds face threats from habitat loss due to human activities, climate change, and pesticide use. 

Conservation efforts focus on preserving their natural habitats, raising awareness about the importance of maintaining biodiversity, and implementing sustainable practices to mitigate human-induced impacts on their ecosystems.
