Bluebirds
The Happiness and Devotion of Bluebirds
Every spring, Mountain and Western Bluebirds return to the Front Range for courtship and nesting after spending the fall and winter in the southwestern US.
Bluebirds are often seen as the harbingers of spring and good fortune, or as symbols of happiness and devotion. There is always something so thrilling about seeing that first flash of brilliant blue in the spring and to know that the Bluebirds are returning. Every spring, Mountain and Western Bluebirds return to the Front Range for courtship and nesting after spending the fall and winter in the southwestern United States and northern Mexico.
Males often begin courtship by selecting potential nest cavities and showing them off to females, fluttering at the entrance and carrying nesting material inside as an invitation. If the female approves, she takes the lead in building the nest—crafting a neat cup of grasses—while the male stands guard, defends the territory, and occasionally brings materials or food.
Once eggs are laid, Bluebirds truly shine as partners. Females do most of the incubation, but males remain closely involved, bringing food to the female and later helping feed and protect the chicks. Together, the pair raises their young, sometimes producing multiple broods in a single season. It’s a beautiful example of cooperation, commitment, and shared responsibility.
You can help support these feathered couples by providing safe nesting opportunities in your community. If you have suitable open habitat—such as grassland, meadow edges, or lightly wooded areas—you may be able to install a Bluebird nest box in your yard. When installed correctly and in appropriate habitat, nest boxes provide safe, secure nesting sites for cavity-nesting birds. They can help offset the loss of natural cavities, support local Bird populations, and offer people a front-row seat to one of nature’s most rewarding love stories.
Here at the Denver Audubon, we offer well-designed nest boxes built specifically for Bluebirds and other cavity nesters, along with guidance on proper placement and care. You can also get involved with Bluebirds by joining our small Nest Box Monitoring Program. Volunteers help check boxes throughout the breeding season, collect valuable data, and ensure birds have a safe place to raise their families.
This Valentine’s Day, consider sharing the love with Colorado’s bluebirds. Whether by putting up a nest box, lending your time as a monitor, or supporting a nest box through a donation, you can play a part in one of nature’s most heartwarming love stories.
